问题 How do you persist a MPMediaItemCollection object using NSUserDefaults? The MPMediaItemCollection object is a single song selected from the iPod. I have been struggling with this for hours! Anyone have any ideas or alternatives to NSUserDefaults or a conversion from MPMediaItemCollection, or anything?! Thanks... 回答1: First convert/encode the MPMediaItemCollection to an NSData Object and store it using NSUserDefaults using: NSData *data = [NSKeyedArchiver archivedDataWithRootObject

问题 Im playing about with apples addMusic sample app in xcode, as im looking to be able to add similar functionality (playing a queue of music selected by the user in the background of the app). It does this annoying thing where the music player briefly stops before playing again when the user hits the 'Done' button after picking their song selections in the built in MediaPicker. - I'm assuming this is because of the method apple used, which applies a new array as the queue, and resets the now

问题 I'm working on code that looks at the user's videos and passes them along to AVPlayer by way of an AVPlayerItem which takes a URL. To get all the videos on an iOS device, you can do: let videoNumber = MPMediaType.anyVideo.rawValue let predicate = MPMediaPropertyPredicate.init(value: videoNumber, forProperty: MPMediaItemPropertyMediaType) let query = MPMediaQuery.init() query.addFilterPredicate(predicate) if let items = query.items { mediaCollection = MPMediaItemCollection(items: items) // -1

I want it so that this item can be stored if the user is to shut the app and reopen it another time.

How Do You Obtain the “Purchase Date” or “Date Added” from MPMediaItems in iPod Library

由 戏子无情 提交于 2019-11-29 15:18:36
As users download new songs into their iPod Music library from the iTunes Store, I would like to programmatically list those songs in a table view. Is it possible to obtain the "Date Added" or "Purchase Date" from the MPMediaItemCollection? I see there are property keys such as play count and last played date. I know the data exists because it can be viewed in iTunes, but I am not finding it. Any suggestions on where to find this or how to derive it? As you can see in Apple Documentation for MPMediaItem http://developer.apple.com/library/ios/#documentation/mediaplayer/reference/MPMediaItem
