问题 The App Programming Guide for tvOS briefly states that There is no persistent local storage for apps on Apple TV. This means that every app developed for the new Apple TV must be able to store data in iCloud and retrieve it in a way that provides a great customer experience. Does this mean NSUserDefaults is unavailable? What mechanisms are available for data storage? 回答1: According to an Apple Staff member on the devforums, you can use NSUserDefaults on tvOS for up to 500 kb of data: https:/

问题 I have a UICollectionView which contains 12-13 UICollectionViewCells. I can easily focus on the UICollectionViewCells and everything works. There is a UIButton outside the UICollectionView.

Any ideas what is going on? 回答1: You should use a UIFocusGuide that encompasses the UIButton you want to focus. Make the

问题 Trying to build a tvOS app and one of the use cases I have is to be able to link off and open another app in the Apple TV App Store directly on a button click. Can someone please share a code snippet to enable this? 回答1: I have figured this out by examining the device console output. The trick is to use the com.apple.TVAppStore scheme instead of itms-apps .

问题 I am putting n avplayer inside of a view controller to customize some other elements of the view controller but I still want the playback and scrubbing controls used in AVPlayerViewController. Is there a way to enable these controls for the Avplayer when I am not using AvPlayerViewcontroller? 回答1: No. The usual solution (explicitly advised by Apple) is to use the AVPlayerViewController as an embedded view controller - i.e., make your view controller a custom parent view controller and the

问题 How would one play a YouTube video on Apple tvOS? YouTube's embed feature works in iOS 9 as the OS has a UIWebView we can embed it into. The new tvOS does not include a UIWebView so I cannot see a way to embed the YouTube video. 回答1: UIWebView and MPMoviePlayerController are not available for tvOS. Our next option is to use AVPlayer to play YouTube videos. AVPlayer cannot play a YouTube video from a standard YouTube URL, ie. https://www.youtube.com/watch?v=8To-6VIJZRE . It needs a direct URL

问题 Apple has released it's SDK for apple tv yesterday. Most apps for TVs are web based (html, javascript and css) and I would like to port an existing tv web app to the tvOS.
