iPhone 배경 음악 플레이어

Question

누구나 나를 튜토리얼로 안내하거나 배경 음악을 재생할 실제 코드를 보여줄 수 있습니까? 나는 시작하고 멈출 수 있어야한다. 당신이 알고있는 임무가 아닙니다. 내 임무는 이미 끝났어. 그냥 음악을 추가하고 싶은데 어떻게하는지 모르겠다. 감사! http://developer.apple.com/library/ios/#DOCUMENTATION/AVFoundation/Reference/AVAudioPlayerClassReference/Reference/Reference.html

Answer 1

당신은 AVAudioPlayer

//You have to import AvFoundation to use AVAudioPlayer 
#import <AVFoundation/AVFoundation.h> 

-(void) playMusicFile:(NSString *) songName 
{ 
    NSString *musicFile = [[NSBundle mainBundle] pathForResource:songName ofType:@"mp3"]; 

    NSError *soundError = nil; 
    self.audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:musicFile] error:&soundError]; 
    if(self.audioPlayer == nil) 
    { 
     NSLog(@"%@",soundError); 
    } 
    else 
    { 
     //Delegation is optional but it helps you do stuff after song finished playing etc 
     [self.audioPlayer setDelegate:self]; 
     //Set number of repeats, 0 is default plays once, negative values makes it play infinitely 
     [self.audioPlayer setNumberOfLoops:0]; 
     //Prepare to play is not always necessary, but otherwise it can take time to play 
     [self.audioPlayer prepareToPlay]; 
     [self.audioPlayer play]; 
    } 
} 

//This is the delegate called after the song finished playing, you can use it to play other songs, or do other stuff 
-(void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag 
{ 
    ... 
} 

이 중지 및 일시 중지 사용할 수 있습니다.

Answer 2

AVPlayer 및 AVAudioPlayer 작동합니다 :

//You can easily stop and pause using: 
[self.audioPlayer stop]; //Stop doesn't work as you would expect. It doesn't set the current time to 0 but only undoes the setup you had with the audioplayer. 
[self.audioPlayer pause]; 

//It is possible to call [self.audioPlayer play] after each method and playback will continue from where it left off.
