ios_guides's Issues

Color matching via the color picker

Sometimes you have an image asset that has some background color. Let's say you want to set the background color of some view to match the color of the asset. If you use the dropper in the color picker, the color won't match.

Can you find the solution for this for Mavericks (I think it's different for earlier versions of OS X) and create a guide for it?

Bug in custom tab bar

https://github.com/codepath/ios_guides/wiki/Creating-a-Custom-Tab-Bar

After following the tutorial, I successfully run the custom tab bar app. However, there will be a blank gap between tab bar view and the first content view loaded in viewDidLoad(). Other content view works great.

Update: My content view is with scroll view, and it's the bug origin.

View Animation Guide

update for ios9

Search Bar remain on top of the table, while scrolling through cells

Hello.
I'm trying to make this example

https://github.com/codepath/ios_guides/wiki/Search-Bar-Guide#using-uisearchcontrollers-ios-8

but i also want to keep it on the top of the table view even if the user is scrolling !

With this line

tableView.tableHeaderView = searchController.searchBar you set it as a Header of the tableView.
Is there any way to make it work as i want it too?
Thanks!

Objective-C Guides

Hi! Thank you for the fantastic guides on iOS. Is the Objective-C-only guide still available? @(from before the course was in Swift)

Moving views with the keyboard

There's already a guide for keyboard events - http://guides.codepath.com/ios/Registering-for-Keyboard-Events. Add a use case guide for moving some textfields with keyboard appearance/disappearance.

Custom Tab Bar

You have great tutorial about custom tab bar. The problem is that there is no information about how to create navigation for this case.

Better Designer Guide Organization

From Tim -> in the designer guides, can you create another category for “Views”. There are things that are in "Animating and Responding to User Input” that should probably be moved to the “Views” category. Also, “UIKit Dynamics” doesn’t seem to belong in “Common Views and Controllers"

All links should name the page they are going to

Instead of 'Guide' the link should say 'Using UIPageControl', etc.

Debugging Guide

Guide for AppIcons

@timothy1ee
Would be useful to show how to satisfy the minimum number of icons for app submission.

Table View Guide UIRefreshControl

func refreshControlAction(refreshControl: UIRefreshControlAction) {
should be
func refreshControlAction(refreshControl: UIRefreshControl) {
As I was getting with UIRefreshControlAction so changed it to UIRefreshControl. It worked.

Document unretweeting

I'm not sure how to unretweet, but I know that many people struggle with it. I've been told the below is true. Can you test and write this up? This probably belongs in an internal page to the courses portal. Just add a .md file to the pages folder, and you can link to it from the assignments page.

1. You always want to be sending the include_my_retweet param - this should make sure that you're getting back the user/self tweet rather than just the original tweet (i.e. someone else's tweet). (You should be able to pass this param for a single status as well)
1. At Twitter, each status in our model had 2 IDs - one was just the status ID and the other was the representedStatusId - this way we would keep the info for both the original status and the RT status (if one existed, otherwise these values were the same).

[question] React Native

As CodePath is a Mobile training, community and mentorship done right.

I think you guys should create a react_native_guides like the android and ios ones

Thanks for the great effort to make great guides

Code Blocks as Images should be discouraged

As Swift evolves, this practice should be discouraged. It will be hard to modify/update code if code blocks are pasted as images.

Example: http://guides.codepath.com/ios/Table-View-Guide

Auto Layout in Code

There should be a guide to define Layouts using only code.

There is some libraries that simplify this task:

Cartography - https://github.com/robb/Cartography
SwiftBox - https://github.com/joshaber/SwiftBox
FLKAutoLayout - https://github.com/floriankugler/FLKAutoLayout

Optionally Add Formatting to Code Snippets

If you add Language (Swift) to tickmarks in Code Snippet Markup, color formatting with ensue: (see below)

Review Assignment #2

Clarify the second assignment.

Update filter screenshot. I just added a screenshot of the real app, but that's deceptive because those filter options aren't available in the Yelp API. You can use this student implementation to create a better screenshot: https://github.com/swaroopbutala/yelpiOS
Add a link to the Yelp categories.
Create a use case guide for embedding the search bar in the navigation bar. I'm not sure what the right way to do this is, you might have to investigate. In the past, I've set the search bar as the titleView of the navigation bar. That works for simple styling, but it has some weird visual glitches when popping/pushing. I've also embedded the search bar in a uiview and set that to the titleView. That fixed the visual glitches, but it was unclear how to dimension the UIView properly.
