Question

在iOS 8.2上播放音频的最佳方法是什么？

Answer 1

最简单的方法是像#import <AudioToolbox/AudioToolbox.h>那样导入AudioToolbox框架，然后你需要做的就是：

NSString *soundPath = [[NSBundle mainBundle] pathForResource:@"Beep" ofType:@"mp3"];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((__bridge CFURLRef)[NSURL fileURLWithPath:soundPath], &soundID);
AudioServicesPlaySystemSound(soundID);

这对于像beeps e.t.c这样的非常短的声音来说是最好的，因为你不会像对AVAudioPlayer一样控制声音。

Answer 2

使用AVAudio - 使用AudioToolbox进行更多编码，但也更灵活（如果将来需要它）

#import <AVFoundation/AVFoundation.h>

1

//conform to delegate and make a property
@interface ViewController () <AVAudioPlayerDelegate>
@property (nonatomic, strong) AVAudioPlayer *audioplayer; //the player
@end

2

//have a lazy property for the player! where you also tell it to load the sound
#define YourSound @"sound.caf"
- (AVAudioPlayer *)audioplayer {
    if(!_audioplayer) {
        NSURL *audioURL = [[NSBundle mainBundle] URLForResource:YourSound.stringByDeletingPathExtension withExtension:YourSound.pathExtension];
        NSData *audioData = [NSData dataWithContentsOfURL:audioURL];
        NSError *error = nil;
        // assing the audioplayer to a property so ARC won't release it immediately
        _audioplayer = [[AVAudioPlayer alloc] initWithData:audioData error:&error];
        _audioplayer.delegate = self;
    }
    return _audioplayer;
}

//play
- (void)action {
    [self.audioplayer play];
}
