使用 Objective C 在设备上播放声音

Question

我已经在此处查看了很多关于此问题的答案，但无法解决任何问题。

这是我的问题，我试图在按下按钮时播放声音，这里是文件所在的位置

这是我的代码

- (void)playSoundWithOfThisFile:(NSString*)fileName {

NSString *soundFilePath = [NSString stringWithFormat:fileName,
                           [[NSBundle mainBundle] resourcePath]];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];

AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL
                                                               error:nil];
player.numberOfLoops = 1;

[player play];

}

当我运行通过代码得到的值如下

fileName = Mummy.mp3

`soundFilePath = Mummy.mp3`  (I've had it Sounds/Mummy.mp3 and this doesn't work either)

soundFileURL = Mummy.mp3 -- 文件:///

player = nil

如有任何帮助，我们将不胜感激。如果我发现它的错误只是一个没有信息的一般错误

Answer 1

试试这个。

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Mummy" ofType:@"mp3"];  

NSURL *soundFileURL = [NSURL fileURLWithPath:filePath];
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL
                                                               error:nil];
player.numberOfLoops = 1;
[player play];

pathForResource: ofType:

Answer 2

尝试使用下面的代码

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

别忘了导入

#import <AudioToolbox/AudioToolbox.h>

Answer 3

 NSString *path = [[NSBundle mainBundle] pathForResource: @"how_to_play" ofType: @"mp3"];
            if(!self.theAudio)
            {
                self.theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
                self.theAudio.delegate = self;
                [self.theAudio play];
            }

输入viewcontroller.h

 < AVAudioPlayerDelegate>

@property(nonatomic,strong) AVAudioPlayer *theAudio;
