AVAudioPlayer on Lock Screen

由 跟風遠走 提交于 2019-11-29 03:28:14
问题 I've implemented an audio player using AVAudioPlayer (not AVPlayer ). I'm able to handle the remote control events with the following method. It works quite alright so far, however I see two more subtypes for these events: UIEventSubtypeRemoteControlEndSeekingForward and UIEventSubtypeRemoteControlEndSeekingBackward . - (void)remoteControlReceivedWithEvent:(UIEvent *)event { //if it is a remote control event handle it correctly if (event.type == UIEventTypeRemoteControl) { if (event.subtype =

Change lock screen background audio controls text?

问题 I have an iOS app that streams background audio using AVAudioSession. It is working correctly, but I am curious, is there any way to change the text on the lock screen audio controls? Right now it simply displays the name of my app, but I would like to change it to the name of the track. Additionally, the multi-tasking bar has no text under the controls- is there a way to add the track name there, as the iPod app does? 回答1: iOS 5 now supports setting the track title as well as an album art

How do you do that? Read the documentation: MPNowPlayingInfoCenter And here is an example code that will work on iOS 5 and it will not crash on older versions of iOS. Class playingInfoCenter = NSClassFromString(@"MPNowPlayingInfoCenter"); if (playingInfoCenter) { MPNowPlayingInfoCenter *center = [MPNowPlayingInfoCenter defaultCenter]; NSDictionary *songInfo = [NSDictionary dictionaryWithObjectsAndKeys: @"Some

I have mp3 files stored on the iPhone and I my application should to be able to read the ID3 information, i.e length in seconds, artist, etc. Does anyone know how to do this or what library to use in Objective-C?

Is there a public way to force MPNowPlayingInfoCenter to show podcast controls?

由 半世苍凉 提交于 2019-11-27 05:58:21
I would like Control Center (via MPNowPlayingInfoCenter) to show the forward 15 seconds / back 15 seconds controls that Apple shows with podcasts, like so: The utter lack of documentation tells me that there's no obvious way to do this, but has anyone out there found any non-obvious way to force this without resorting to a private method? I've already got my handling for the forward/back button set up to advance appropriately, I'd just like to use the more appropriate UI. Any help would be greatly appreciated. OK so I had a bit of time on my hands and so I followed the breadcrumb.… This is
