A way to represent what you’re sharing.

About

This project provides a preview of items being shared via UIActivityViewController. Example:

// standard activity view controller
let vc = UIActivityViewController(activityItems: [shareText])

// custom activity view controller with a preview 
let vc = VisualActivityViewController(text: shareText)

Features

• Text, Image, and URL previewing
• Swipe gesture to dismiss the share sheet
• Easy customization (match your app’s style)

Requirements

• iOS 9.0+
• Xcode 9.0+

Installation

To install, simply add the VisualActivityViewController.swift file to your project.

Advanced Usage

There are quite a few different options to customize the appearance of the preview. Check out the example project to see how some of these options work.

/// The duration for the preview fading in
var fadeInDuration: TimeInterval = 0.3

/// The duration for the preview fading out
var fadeOutDuration: TimeInterval = 0.3

/// The corner radius of the preview
var previewCornerRadius: CGFloat = 12

/// The corner radius of the preview image
var previewImageCornerRadius: CGFloat = 3

/// The side length of the preview image
var previewImageSideLength: CGFloat = 80

/// The padding around the preview
var previewPadding: CGFloat = 12

/// The number of lines to preview
var previewNumberOfLines: Int = 5

/// The preview color for URL activity items
var previewLinkColor: UIColor = UIColor(red: 0, green: 0.47, blue: 1, alpha: 1)

/// The font for the preview label
var previewFont: UIFont = UIFont.systemFont(ofSize: 18)

/// The margin from the top of the viewController's window
var previewTopMargin: CGFloat = 8

/// The margin from the top of the viewController's view
var previewBottomMargin: CGFloat = 8

visualactivityviewcontroller's Issues

preview don't remove from window

preview don't remove from window, will create constraint bug, I think you should remove it by this code;

 override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        UIView.animate(withDuration: fadeOutDuration) {
            self.preview?.alpha = 0
            if let window = self.view.window,
                window.subviews.contains(self.preview) {
                self.preview.removeFromSuperview()
            }
        }
    }

UIActivityViewController Can't share with WeChat friends

Whatsapp share

Hello,
Its not sharing image in the whatsapp. How can I handle it?

applicationActivities

Please add applicationActivities to VisualActivityViewController
example : VisualActivityViewController(text: "", applicationActivities: Freedom.browsers())

Expose all variables in Objective C

It would be extremely useful to expose all the variables to Objective C, as they are in Swift.

Could be done using @objcMembers prefix to the VisualActivityViewController class.

Does not work on iOS 13

VisualActivityViewController doesn't show a UIView on iOS 13. This version is working fine till iOS 12.4. What is the possible fix.

Thank You

UIActivityViewController dont

Preview doesn't fit the screen width

it works well on simulator, on device the preview doesn't fit the screen width and it's anchored to the top, at least on my iPhone 7, iOS 11.0.2

preview doesn't get removed during viewWillDisappear on iPad

Autoresizing Mask Autolayout error hides the Preview on iPad (works as expected on iPhone)

Hello! I updated to the latest version, I'm getting a layout constraints error on iPad. The preview view doesn't display at all on iPad, and I'm guessing it's related to this error.

My share items are a String and an URL.

It works fine as expected on iPhone. Yes, I'm setting sourceRect and sourceView

Here is the error:

[LayoutConstraints] Unable to simultaneously satisfy constraints.
	Probably at least one of the constraints in the following list is one you don't want. 
	Try this: 
		(1) look at each constraint and try to figure out which you don't expect; 
		(2) find the code that added the unwanted constraint or constraints and fix it. 
	(Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSAutoresizingMaskLayoutConstraint:0x600001516620 h=--& v=--& UIView:0x7fbe60d56940.midY == 146   (active)>",
    "<NSAutoresizingMaskLayoutConstraint:0x60000150dae0 h=--& v=--& UIView:0x7fbe60d56940.height == 292   (active)>",
    "<NSLayoutConstraint:0x600001516080 UIVisualEffectView:0x7fbe60d56d40.top >= UILayoutGuide:0x600004f902a0'UIViewSafeAreaLayoutGuide'.top + 8   (active)>",
    "<NSLayoutConstraint:0x600001516cb0 UIVisualEffectView:0x7fbe60d56d40.bottom == UIView:0x7fbe60d56940.top - 8   (active)>",

)

and here is my call

let vc = VisualActivityViewController(activityItems: [shareText, url], applicationActivities: nil)
                            
if let popoverPresentationController = vc.popoverPresentationController {
   popoverPresentationController.sourceRect = cell.bounds
   popoverPresentationController.sourceView = cell
}
                            
self.present(vc, animated: true, completion: nil)

Thanks!
