Ios 如何增加声音文件（如uiimagefile）的值

我有以下代码：

h

不起作用

pathForResource方法采用简单的NSString，而不是格式。这样做：

    NSString *name = [NSString stringWithFormat:@"sfx%ld.wav", (long) (value+1)];
    NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:nil];
    NSURL *url = [[NSURL alloc] initFileURLWithPath:path];
    self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url  error:nil];

试着跟随

NSString * strName = [NSString stringWithFormat:@"sfx%ld", (long) (value+1)];
NSString * strPath = [[NSBundle mainBundle] pathForResource:strName ofType:@"wav"];
NSURL * urlPath = [NSURL fileURLWithPath:strPath];
self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:urlPath error:NULL];

我想我得说点什么，比如按按钮之类的？或者音频播放器是否从initwithframe继承了它？

self.audioplayer=[[AVAudioPlayer alloc]InitWithContentsURL:[[NSURL alloc]initFileURLWithPath:[[NSBundle mainBundle]pathForResource:[NSString stringWithFormat:@sfx%ld.wav，long value+1]]错误：NULL]；谢谢！但是现在我得到一个错误：'AVAudioPlayer'没有可见的@interface声明选择器'initWithContentsOfURL:'我已经导入了导入和一个带有@property nonatomic AVAudioPlayer*audioplayer的属性；@vladimir:我们必须使用[[AVAudioPlayer alloc]initWithContentsOfURL:urlPath错误：NULL]；而不是[[AVAudioPlayer alloc]initWithContentsOfURL:urlPath]；谢谢。但在这里它崩溃了：**由于未捕获的异常“NSInvalidArgumentException”而终止应用程序，原因：'***-[NSURL initFileURLWithPath:]：nil字符串参数'***检查strName的值。是否为nil？我的错误，它不再崩溃，在错误的示例项目中，呵呵…但它通过单击相关图像不会播放声音。我不是说他应该通过触摸播放示例吗？您是否调用[self.audioplayer play]；是的，直接在initWithFrame方法中播放

    NSString *name = [NSString stringWithFormat:@"sfx%ld.wav", (long) (value+1)];
    NSString *path = [[NSBundle mainBundle] pathForResource:name ofType:nil];
    NSURL *url = [[NSURL alloc] initFileURLWithPath:path];
    self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url  error:nil];

NSString * strName = [NSString stringWithFormat:@"sfx%ld", (long) (value+1)];
NSString * strPath = [[NSBundle mainBundle] pathForResource:strName ofType:@"wav"];
NSURL * urlPath = [NSURL fileURLWithPath:strPath];
self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:urlPath error:NULL];

-(id) initWithFrame: (CGRect)frame andPosition: (NSInteger)pos andValue: (NSInteger)value {
self = [super initWithFrame: frame];
if (self) {
    self.frontImage = [UIImage imageNamed:[NSString stringWithFormat: @"card-%ld.png", (long) (value+1)]];


    NSString * strName = [NSString stringWithFormat:@"sfx%ld", (long) (value+1)];
    NSString * strPath = [[NSBundle mainBundle] pathForResource:strName ofType:@"wav"];
    NSURL * urlPath = [NSURL fileURLWithPath:strPath];
    self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:urlPath error:NULL];
    [self.audioplayer play];

}
return self;
}
