1. Create avaudiosession when creating player [OBJC]View PlainCopy

1. Avaudiosession *session = [Avaudiosessionsharedinstance];
2. [Session Setcategory:avaudiosessioncategoryplaybackerror: nil];
3. [Session setActive:YES error: nil];

2. Add a field to the Plist file

Required Background modes

To add a background play here:

APP plays audio or streams audio/video using AirPlay

3. Add the following code when the device will suspend the app

[OBJC]View PlainCopy

2. -(void) applicationwillresignactive: (uiapplication *) application {
6. if ([Mediaplayerplayer]. playstatus = = mediaplayerplaystatusplaying) {
8. uidevice* device = [Uidevicecurrentdevice];
10. if ([Devicerespondstoselector:@selector (ismultitaskingsupported)]) {
12. if (device. multitaskingsupported) {
14. if (device. multitaskingsupported) {
16. if ([Mediaplayerplayer]. Bgtaskid ==uibackgroundtaskinvalid) {
18. [Mediaplayerplayer]  . bgtaskid = [[Uiapplicationsharedapplication]beginbackgroundtaskwithexpirationhandler:NULL];
20. }
22. }
24. }
26. }
28. }
30. }

Add the following code when the device enters the foreground

[OBJC]View PlainCopy

1. if ([Mediaplayerplayer]. Bgtaskid!=uibackgroundtaskinvalid) {
2. [[Uiapplicationsharedapplication]endbackgroundtask:[mediaplayerplayer]. Bgtaskid];
3. [Mediaplayerplayer]  . Bgtaskid =uibackgroundtaskinvalid;
4. }

Using these three steps will basically guarantee long-time playback problems in the background, and will not cause the playback to stop because the app hangs in the background.
