iphone avaudiofoundation循环中的声音完成

Question

在继续执行代码之前是否可以强制音频文件完成播放？在下面的例子中，我想要一个音频文件播放多次，因为我有数组中的项目。目前它完成循环只播放一次。我在AVFoundation框架内使用AVAudioPlayer。

for (int i = 0; i<[Array count]; i++) { 
    if ([Array objectAtIndex:i] == @"Red") { 
     NSLog(@"red"); 
     [self.player play]; 
    } 
    if ([Array objectAtIndex:i] == @"Blue") { 
     NSLog(@"blue"); 
     [self.player play]; 
    } 
    if ([Array objectAtIndex:i] == @"Green") { 
     NSLog(@"green"); 
     [self.player play]; 
    } 
    if ([Array objectAtIndex:i] == @"Yellow") { 
     NSLog(@"yellow"); 
     [self.player play]; 
    } 
} 

我还使用方法audioPlayerDidFinishPlaying来测试它是否完成五次，但只有一次达到此方法。

-(void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL) completed{ 
    if ((completed) == YES){ 
     NSLog(@"audio finish"); 
     return; 
    } 
} 

是否有可能在音频播放时保持for循环？

理论上控制台应改为：color->音频finish-> color->音频finish-> REPE

也许你能告诉AudioPlayer当您收到finishedPlaying通知喜欢玩：

int arrayIndex = 0 
NSArray* array; //initialized somewhere.. 


-(void)myFunction 
{ 
    if(arrayIndex < [array length]) 
    { 
    NSArray* colors = [NSArray arrayWithObjects:@"Red",@"Blue",@"Green",@"Yellow",nil]; 
    if([colors indexOf:[array objectAtIndex:arrayIndex]] != NSNotFound) 
    { 
     NSLog([array objectAtIndex:arrayIndex]); 
     [self.player play]; 
    } 
    arrayIndex++; 
    }else{ 
    NSLog(@"audio finish"); 
    } 
} 

-(void) audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)  completed{ 
    if ((completed) == YES){ 
     [self myFunction]; 
    } 
} 

-(void)start_it_up 
{ 
    arrayIndex = 0; 
    [self myFunction]; 
}
