AVPlayer video not resuming after app become Active - ios

Question

AVPlayer video not resuming from where it left, instead video starts from beginning. Here is my code.Can anyone help me??
-(void)appEnteredForeground:(NSNotification*)notification {
if(playerViewController.player.status == AVPlayerStatusReadyToPlay &&
playerViewController.player.currentItem.status == AVPlayerItemStatusReadyToPlay) {
total_duration = self.playerViewController.player.currentItem.duration;
[self.playerViewController.player seekToTime:currentTime];
[_playerViewController.player play];
}
}
-(void)appEnteredBackground:(NSNotification*)notification {
[playerViewController.player pause];
currentTime = [playerViewController.player currentTime];
[playerViewController.player seekToTime:currentTime];
}

Answer 1

1.It's seek to time problem, when u ask it to seek to time, it can't be done as it's already in background. Why did u seek to time when u enter background? pause should do just fine. remove the following line.
[playerViewController.player seekToTime:currentTime];
2.you had better pause in resign active notification instead of background notification. because the last one shall be triggered in a few seconds later after pressing the home button
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(becomeActive) name:UIApplicationDidBecomeActiveNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(resignActive) name:UIApplicationWillResignActiveNotification object:nil];
}
- (void)becomeActive {
NSLog(#"active");
if(playerViewController.player.status == AVPlayerStatusReadyToPlay &&
playerViewController.player.currentItem.status == AVPlayerItemStatusReadyToPlay) {
total_duration = self.playerViewController.player.currentItem.duration;
[self.playerViewController.player seekToTime:currentTime];
[_playerViewController.player play];
}
}
- (void)resignActive {
NSLog(#"resign active");
[playerViewController.player pause];
currentTime = [playerViewController.player currentTime];
}
