Fist you need to set up AVAudioSessionCategoryPlayback. you need to do the Xcode Capabilities view for your project, select Audio and AirPlay in the Background Modes section.
1、在AppDelegate.m下
#import "AppDelegate.h"
#import "AVFoundation/AVFoundation.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive: YES error: nil];
return YES;
}
2、生成完player之后将playerLayer给pipcontroller，
@property (nonatomic, retain) AVPictureInPictureController *pipController;
-(void)setupSuport
{
if([AVPictureInPictureController isPictureInPictureSupported])
{
printf("lee setupSuport\n");
self.pipController = [[AVPictureInPictureController alloc] initWithPlayerLayer:self.playerLayer];
self.pipController.delegate = self;
}
else
{
// not supported PIP start button desable here
}
}
//监听pip
- (void)pictureInPictureController:(AVPictureInPictureController *)pictureInPictureController restoreUserInterfaceForPictureInPictureStopWithCompletionHandler:(void (^)(BOOL restored))completionHandler{
printf("lee restoreUser\n");
}
- (void)pictureInPictureControllerDidStopPictureInPicture:(AVPictureInPictureController *)pictureInPictureController{
printf("lee DidStop\n");
}
- (void)pictureInPictureControllerDidStartPictureInPicture:(AVPictureInPictureController *)pictureInPictureController{
printf("lee DidStart\n");
}
- (void)pictureInPictureControllerWillStopPictureInPicture:(AVPictureInPictureController *)pictureInPictureController{
printf("lee WillStop\n");
}
- (void)pictureInPictureController:(AVPictureInPictureController *)pictureInPictureController failedToStartPictureInPictureWithError:(NSError *)error{
printf("lee failedToStart\n");
}
- (void)pictureInPictureControllerWillStartPictureInPicture:(AVPictureInPictureController *)pictureInPictureController{
printf("lee WillStart\n");
}
3、建立点击事件 pip响应
- (IBAction)pipBtnClick:(id)sender {
NSLog(@"lee pipBtnClick\n");
if (self.pipController.pictureInPictureActive) {
[self.pipController stopPictureInPicture];
}
else {
[self.pipController startPictureInPicture];
NSLog(@"lee pipBtnClick--start\n");
}
}
ps.按home键没有成功pip
