Compose bar from iOS 7 Messages.app

PHFComposeBarView

More screenshots: without text and with text.

---

This is a precise reconstruction of the compose bar from the iOS Messages.app, mimicking the behaviors and graphics while also allowing you to customize many aspects of it.

It basically consists of a text view, a placeholder label, a utility button located to the left of the text view, and a main button located to the right of the text view.

If you're looking for something that works with iOS 5 and 6 featuring the old look and feel, have a look at version 1.1.1.

Features

• title of main button (the one on the right) can be changed
• tint color of main button can be changed
• title of the placeholder can be changed
• placeholder is exposed as a property for further customization
• text view is exposed as a property for further customization
• utility button (the one on the left) can be shown by setting the utility button image (best results for gray images (~56% white) on transparent background with up to 50pt side length)
• optional character counter when specifying a max character count (similar to typing an SMS in Messages.app; the max char count limit is not imposed)
• uses delegation to notify of button presses
• forwards delegation methods from the text view
• automatically grows when text wraps
• posts notifications and sends delegate messages about frame changes before and after the change so you can adjust your view setup
• by default grows upwards, alternatively downwards
• max height for growth can be specified in terms of points or line numbers
• has a translucent blurred background

Installation

The prefered way is to use CococaPods.

pod 'PHFComposeBarView', '~> 2.0.1'

If you can't use CocoaPods for some reason (you really should though, it's the cool kid on the block), then grab the files in Classes/ and put it in your project. The code uses ARC, so make sure to turn that on for the files if you're not already using ARC. There's a dependency on PHFDelegateChain, so make sure to add that to your project, too.

Usage

The compose bar visible in the demo above was created as follows:

CGRect viewBounds = [[self view] bounds];
CGRect frame = CGRectMake(0.0f,
                          viewBounds.size.height - PHFComposeBarViewInitialHeight,
                          viewBounds.size.width,
                          PHFComposeBarViewInitialHeight);
PHFComposeBarView *composeBarView = [[PHFComposeBarView alloc] initWithFrame:frame];
[composeBarView setMaxCharCount:160];
[composeBarView setMaxLinesCount:5];
[composeBarView setPlaceholder:@"Type something..."];
[composeBarView setUtilityButtonImage:[UIImage imageNamed:@"Camera"]];
[composeBarView setDelegate:self];

To get notified of button presses, implement the optional methods from the PHFComposeBarViewDelegate protocol:

- (void)composeBarViewDidPressButton:(PHFComposeBarView *)composeBarView;
- (void)composeBarViewDidPressUtilityButton:(PHFComposeBarView *)composeBarView;

To get notified of frame changes, either listen to the notifications (PHFComposeBarViewDidChangeFrameNotification and PHFComposeBarViewWillChangeFrameNotification) or implement the optional delegate methods:

- (void)composeBarView:(PHFComposeBarView *)composeBarView
   willChangeFromFrame:(CGRect)startFrame
               toFrame:(CGRect)endFrame
              duration:(NSTimeInterval)duration
        animationCurve:(UIViewAnimationCurve)animationCurve;
- (void)composeBarView:(PHFComposeBarView *)composeBarView
    didChangeFromFrame:(CGRect)startFrame
               toFrame:(CGRect)endFrame;

Note that all methods from the UITextViewDelegate protocol are forwarded, so you can add your own behavior to the text view such as limiting the text length etc.

Refer to PHFComposeBarView.h for the available properties and their descriptions.

phfcomposebarview's Issues

UIBarStyleBlackTranslucent?

Is it possible you implemented a dark version of this? Because It would help a lot as you can see in my screenshot.

Unable to scroll textview after keyboard is dismissed on specific text.

Max Lines: 5
Enter text:
"ff
fef

fef
.
.
.
ff"

Point the cursor at the end of the text and dismiss the keyboard.
You can't scroll the textview at all in this situation (cant see the text either).

autoscroll does not work

why not auto scroll when I type and finish line? How do I fix this error?

Implement via Swift?

Any information how to use this with Swift?

Only show compose bar on keyboard

Is there a way to disable displaying the compose bar at the bottom, and only show it on the keyboard? I'd like a button to trigger the keyboard instead of having the bar there permanently. Thanks!

stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet] check needed

Check stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet] needed to prevent only space message sent.

UIToolbar example

I've been testing PHFComposeBarView inside of a UIToolbar, but it doesn't seem to work on iOS7. Has anybody managed to resize the height of the UIToolBar when embedded inside of a UINavigationController?

Resign First Responder not working with Swift

Hey

For some reason I can never get the view/keyboard to disappear with resignFirstResponder or endEditing. I manage to make it go when the view closes but only by doing UIApplication.sharedApplication().sendAction(Selector("resignFirstResponder"), to: nil, from: nil, forEvent: nil) which is pretty aggressive.

Any thoughts on what my be causing it to stick? I am using Swift 2.1.1 and iOS 9.2

Globally selected text & Image paste

Hello,

I working PHFComposeBarView for chat application. I want to use paste option in text view if i already selected image or text from application or out of application.

When the keyboard comes up, the composebarview gets offset from the bottom by a few pixels.

Here is a video that illustrates the bug:

https://vid.me/W7rx

In iOS 7+, caret is not tracked correctly when return is pressed

Caret tracking works fine if the text is allowed to overflow naturally, but if the user creates new lines with the return key, the caret goes offscreen once the max number of lines is reached. The user can scroll down manually, but as soon as they type, the text view scrolls back to where it was.

We tracked the problem down to the textHeight function. Unfortunately, iOS 7+ introduces side effects to the sizeThatFits: method, so a call to textHeight was interfering with the caret tracking code.

One workaround is to create a copy of the text field and call sizeThatFits: on the copy instead of the real text field.

Textview not accessible to UI tests

Hey @fphilipe, we have an app that makes much use of PHFComposeBarView and as we're aiming to translate it into a couple of dozen languages, we're very keen to make use of UI Tests to automate UI testing, screenshots and video walkthroughs for our translators. Unfortunately we're having problems entering text into the ComposeBar programatically.

It looks like the core of the issue is that the text view is not visible to the underlying accessibility framework that UI Tests depend on.

I've created a minimal test case using your Example app that exhibits the issue. While it's possible to tap the ComposeBar and give the textview focus, the test framework then can't find any textview to type text into.

I've added some acessibilityIdentifiers to help make addressing specific elements easier, but if you look at the application's element subtree that's dumped to the test log, you should be able to see that there's no sign of any textview:

I suspect that this may be related to the fact that the textView is a child of a button, as brought up in #36. I'm sure you had good reason to nest the textview in the button, I'd much appreciate it if you could give us some background so that we can fix or workaround this issue.

Many thanks.

Expending textView for iOS7

It doesn't expand at all in iOS7 for me. Has anyone been able to get it to work?

Insert images

Is it possible to inline images in text field?
Maybe you have an idea to do so?
I am ready to contribute...

crash on iOS7 when pressing return on an empty line.

How to reproduce:

Focus the textfield, press return, it crashes.

The cause

[[self textView] caretRectForPosition:position].origin.y returns inf instead of a regular float.

Hack to prevent from crashing

Ask the method to do nothing if the value is inf

        // Caret is above visible part of text view:
        if (relativeCaretY < 0.0f) {
            offsetYDelta = relativeCaretY;
        }
        // Caret is in or below visible part of text view:
        else if (relativeCaretY > 0.0f) {
            CGFloat maxY = [self bounds].size.height - PHFComposeBarViewInitialHeight;
            // Caret is below visible part of text view:
            if (relativeCaretY > maxY)
                offsetYDelta = relativeCaretY - maxY;
        }

to:

        // Caret is above visible part of text view:
        if (relativeCaretY < 0.0f && relativeCaretY < DBL_MAX) {
            offsetYDelta = relativeCaretY;
        }
        // Caret is in or below visible part of text view:
        else if (relativeCaretY > 0.0f && relativeCaretY < DBL_MAX) {
            CGFloat maxY = [self bounds].size.height - PHFComposeBarViewInitialHeight;
            // Caret is below visible part of text view:
            if (relativeCaretY > maxY)
                offsetYDelta = relativeCaretY - maxY;
        }

It's a hack so I cannot make a pull request. If anybody has a nicer solution...
Thank you!

Regarding Default size increase when load composebar

Hello,

I am using compose bar for my chat application. Application is responsive from as per default font style from setting(Font Zoom Increase Decrease) style. So If font size is larger 53 then change compose bar view in height as default UI for single line text message.

Thanks,

'charCountLabel' visible for one line textView, when custom font is used

Crash while setting the delegate: Acessibility?

Hi,

I've just gone live with an app using the excellent PHFComposeBarView. I've seen a few crashes over the last couple of days when setting the delegate. I'm suspecting something to do with Accessibility (due both to the word appearing in the crash report, and the fact that it seems to be consistently affecting 2 users, but no-one else). It's iOS8 only, and affecting both iPhone 5S and 6+.

The crash report is here: http://crashes.to/s/0321516c355 but I've screens hotted the salient piece here:

I'm not expecting you to fix my bugs :-) But I just wondered if anyone else had seen it and/or figured it out.

Thanks again for a really useful component.

Unable to scroll to caret after inserting NSTextAttachment in textView

I am adding images to compose bar’s textview using NSTextAttachment. But when I add more than 2-3 images, textview is not exactly scrolling to caret. Also when I have a combination of text and images (image at last) and when I tap on last line of compose bar, it does not scroll to last line, it scrolls on first or second line or image. Please check my code :

let attachment = ChatTextAttachment()
attachment.image = thumbImage

// Add NSTextAttachment into attributedString
let attributedString = NSMutableAttributedString(string: "", attributes: [NSFontAttributeName:UIFont.systemFontOfSize(14)])
let attrStringWithImage = NSAttributedString(attachment: attachment)
attributedString.appendAttributedString(attrStringWithImage)
attributedString.appendAttributedString(NSAttributedString(string: "\n", attributes: [NSFontAttributeName:UIFont.systemFontOfSize(14)]))

// Add this attributed string to the current position.
self.composeBar.textView.textStorage.insertAttributedString(attributedString, atIndex: self.composeBar.textView.selectedRange.location)
self.composeBar.textView.select(self)
self.composeBar.textView.selectedRange = NSMakeRange(self.composeBar.textView.attributedText.length, 0 );

self.textViewDidChange(self.composeBar.textView)
self.composeBar.textView.layoutIfNeeded()

ChatTextAttachment is a subclass of NSTextAttachment
Let me know if you need any more details.

[feature] Option to disable automatic button en- & disabling

I'd like to have the button always clickable.

Subview layout incorrect if not allocated using initWithFrame:

Creating a PHFComposeBarView in the following form will result in incorrect sizes for subviews:

PHFComposeBarView *view = [PHFComposeBarView new];
view.frame = CGRectMake(...);

However, this form does work as expected:

PHFComposeBarView *view = [[PHFComposeBarView alloc] initWithFrame:CGRectMake(...)];

[bug] missing isFirstResponder

Please also forward

- (BOOL)isFirstResponder;

Rotation messes up text

When entering text with newlines interspersed, rotating will cause text to disappear from the view, until the delete key is pressed, upon which it returns visible.

To re-create: Enter text, return twice, enter text, immediately rotate.

Why is the textView inside a button?

Hi, I was trying to customize the textView's border to be square and clear, but then I discovered that the border was generated by the button that encloses the textView.

I see that the only function of the button is to becomeFirstResponder. Why is this necessary? Isn't tapping on the textView enough to cause it to take first responder?

Having the button that encloses the textview causes some problems with Accessibility, since I cannot really set the label on the button in a non-hacky way.

Keyboard covers text field

When I add the PHFComposeBarView to my UIVIew, and tap the textfield, the keyboard covers the textfield. How can make the textfield move up with the keyboard.

Thanks.

Attachment cancel button on image of NSTextAttachment

I want to show cross button on top right image for cancel attachment in NSTextAttachment and remove image from text view using particular cross button of that object without use keyboard cursor. Please let me know a way so i can achieve customizations on NSTextAttachment.

--Thanks In Advance

Not scrolling when hitting return

It scrolls perfectly when a new line is created by typing off the end of a line, but if I hit return to add new lines, it doesn't scroll for me — the caret y position just increases off into the unseen ether.

Does anyone else see this behavior? Or did I set something up incorrectly?

Thanks,

Russell.

PHFDelegateChain dependancy as submodule?

Not really an issue, but perhaps and idea to add PHFDelegateChain as a submodule to make it easier to implement?

How to support UIScrollViewKeyboardDismissModeInteractive?

Dragging down separates the box from the keyboard. Is there any way to live-update the frame of this?

Demo and this control does not work iOS7

Do you have a workable demo for iOS7? I tried it on an app using the Pod installer and textfield did not expand vertically when more text was added. Also composeBarViewWillChangeFrame does not fire even after adding notifications for it in my app

Is the purpose to mimic the iMessage app 100%?

I have altered the library code in my app a bit to function more as one would expect.

Namely, I altered button enabling:

- (void)updateButtonEnabled {
    BOOL enabled = [self isEnabled] && [[[[self textView] text] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] length] > 0;

    if (_maxCharCount > 0) {
        enabled = [[[[self textView] text] stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] length] <= _maxCharCount;
    }

    [[self button] setEnabled:enabled];
}

I think this functions a lot more as someone would expect. You do nearly all your checks on the trimmed string, so one would expect the button enabling to be the same. In the above, the button is enabled only when the length of the trimmed textView text is greater than 0 and when it is less than the maxCharCount if the maxCharCount was set.

If the purpose is to 100% mimic the iMessage app, then I won't submit a pull-request, just figure this is more intuitive with how one would expect.

White view over the UITextView not showing the entered text

That's my issue, any help is really apreciated.

Any help is really appreciated

On text reset, the view does't update correctly

You should KVO textView.text, so you can react when the text is resetted to nil or @"".

Compose bar doesn't respond to paste board

I am using "VGPlayer" a third party liberary in my chat app, but after integrating this in my app. my compose bar doesn't responding paste options. Only compose bar didn't works fine but in other screens in textview or textfield paste board working.
Please suggest me how would I fix this.

iOS 6 deprecations

There are some items deprecated in iOS 6 - with iOS 7 coming out it makes sense to make code that supports 6 and 7 so it would be nice if the following could be cleaned up (to avoid deprecation warnings in Xcode and move on to using Apple's latest):

setMinimumFontSize: is deprecated. Should use minimumScaleFactor instead.
UITextAlignmentCenter is deprecated. Should use NSTextAlignmentCenter instead.

Happy to submit a pull request if you'll take it.

iOS 7 theme

Adjust appearance to match the iOS 7 style.

Supporting iOS 6 and iOS 7 themes through conditional compilation would be even better.

The frame change notifications should be a delegate callback, not a notification

It's a bit inconvenient (and unnecessarily unsafe, I might add) to use notifications for the compose bar frame change stuff. It would be much nicer if it were a delegate method.

The only reason I can think of for using notifications here is to mirror the UIKeyboard API; but I suggest that the UIKeyboard API is done in the way it is because there's not any particular UIKeyboard object that the consumer can get his/her hands onto and guarantee an exclusive delegate-relation. But that's not the case here: there's a clear owner to the compose bar, and the delegate relation is the most convenient one, I think.

Thanks for the very nice component, by the way!

Swift/AutoLayout : Bar stays under keyboard when keyboard is presented

Hi there =)

Though I already user PHFComposeBarView successfully in the past, I needed to use it in a swift project, but the ComposeBarView stays under the keyboard all the time.

I didn't have the time to figure out if this was an auto layout issue, or a swift issue (though my first guess would be AutoLayout). Did anyone had the same issue?

Thanks.

iOS 7 and Prior support in one library.

PHFComposeBar via storyboards

Hi there. I really like PHFComposeBar, it's working great for me!

I was able to get this to work with storyboards with one small tweak. Adding an awakeFromNib method like this:

- (void)awakeFromNib
{
  [super awakeFromNib];

  [self calculateRuntimeConstants];
  [self setup];
}

This is essentially mirroring the init call. This helped greatly with not having to mix in-code autoLayout constraints with IB constraints. Thanks for the great drop-in class!
