问题 I'm attempting to put a collection view within the navigation bar, as seen in iMessage group chats where all members have their initials in circles in the nav bar. I found an answer here on SO and I did my best to convert it to iOS10/Swift 3, but the collection view cells are not showing up in the nav bar correctly. Here's my code: import UIKit weak var collectionView: UICollectionView? class ChatController: UIViewController, UICollectionViewDelegate, UICollectionViewDataSource { override

问题 I have an app that been happily shipping for a couple of years. It retrieves RSS Feeds in a UICollectionView. The cellForItemAtIndexPath method sets text and calls a datasource method to load an image from a link specified in the feed. If none exists it loads the web page data and searches for <img> tags to get an image. Once the image is found/loaded the delegate method is called to add the image to the cell. (below) When running in iOS 8 and 9 everything is happy, but when running in iOS 10

问题 I have written a chromakey filter for making the backgrounds of MPEG movies transparent so that you can use a movie file for longer animations without the need for lengthy sequences of PNGs (as is commonly done for some types of iOS animations). I am using AVPlayer , AVVideoComposition , and a custom CIFilter to render the video over a background image. The background image can be changed dynamically by the user interacting with the app. This used to work just fine until iOS 10 came out and
