How to Play Audios ohne Verzögerung mit AVPlayer

Question

Ich benutze AVPlayer. Es spielt Audio nach einiger Verzögerung. Ich möchte einen Ton abspielen, während ich danach auf einen UIButton klicke (Audio), ich möchte ein Video abspielen. Wie kann ich das machen? Kann mir jemand helfen?

-(IBAction) someMethod3:(id) sender { 
[self Playaudio]; 
} 

-(voidPlayaudio { 

NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"tap" ofType: @"mp3"]; 
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath]; 
NSError *error; 
musicplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error]; 
musicplayer.delegate = self; 
[musicplayer prepareToPlay]; 
[musicplayer play]; 
} 

-(void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag 
{ 

[self playVideo:indexvalue]; 
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mainView:) name:AVPlayerItemDidPlayToEndTimeNotification object:nil]; 

} 

-(void) playVideo:(int)index { 

NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:[_videos objectAtIndex:index] ofType: nil]; 
url = [[NSURL alloc] initFileURLWithPath: soundFilePath]; 
AVPlayerItem *currentItem = [AVPlayerItem playerItemWithURL:url]; 
playerViewController = [[AVPlayerViewController alloc] init]; 
playerViewController.videoGravity = AVLayerVideoGravityResize; 
playerViewController.view.frame = self.view.bounds; 
playerViewController.showsPlaybackControls = NO; 
video = [AVPlayer playerWithPlayerItem:currentItem]; 
playerViewController.player = _video; 
playerViewController.view.userInteractionEnabled = false; 
[playerViewController.player play]; 
self.view.autoresizesSubviews = YES; 

[self.view addSubview:playerViewController.view]; 
} 

-(void)Mainview:(NSNotification*)notification { 
UIButton * Button = [[UIButton alloc] initWithFrame: CGRectMake(10, 50, 30,20)]; 

}

Erstellen Sie neue Klasse

import AVFoundation 

class Sound { 

var audioPlayer = AVAudioPlayer() 

init(name: String, type: String) { 
    let coinSound = NSURL(fileURLWithPath: NSBundle.mainBundle().pathForResource(name, ofType: type)!) 
    do { 
     audioPlayer = try AVAudioPlayer(contentsOfURL: coinSound) 
     audioPlayer.prepareToPlay() 
    } catch let error as NSError { 
     print(error.description) 
    } 
} 

func play() { 
    audioPlayer.play() 
} 

func stop() { 
    audioPlayer.stop() 
} 
} 

Relativ Viewcontroller laden der Ton

let testSound = Sound(name: "alarm", type: "caf") 

spielen, wo Sie

testSound.play()
