1、创建播放器时创建AVAudioSession
- AVAudioSession *session = [AVAudioSessionsharedInstance];
- [session setCategory:AVAudioSessionCategoryPlaybackerror:nil];
- [session setActive:YES error:nil];
2、在plist文件中添加字段
Required background modes
在这里添加后台播放：
App plays audio or streams audio/video using AirPlay
3、在设备将要挂起app时添加下面代码
- - (void)applicationWillResignActive:(UIApplication *)application {
-
- if ([MediaPlayerplayer].playStatus == MediaPlayerPlayStatusPlaying) {
- UIDevice* device = [UIDevicecurrentDevice];
- if ([devicerespondsToSelector:@selector(isMultitaskingSupported)]) {
- if(device.multitaskingSupported) {
- if(device.multitaskingSupported) {
- if ([MediaPlayerplayer].bgTaskId ==UIBackgroundTaskInvalid) {
- [MediaPlayerplayer].bgTaskId = [[UIApplicationsharedApplication]beginBackgroundTaskWithExpirationHandler:NULL];
- }
- }
- }
- }
- }
- }
在设备进入前台时添加下面代码
- if ([MediaPlayerplayer].bgTaskId !=UIBackgroundTaskInvalid) {
- [[UIApplicationsharedApplication]endBackgroundTask:[MediaPlayerplayer].bgTaskId];
- [MediaPlayerplayer].bgTaskId =UIBackgroundTaskInvalid;
- }
使用这三步基本可以保证在后台的长时间播放问题，且不会因为后台挂起APP导致的播放停止问题。
