如何增加像 uiimagefile 这样的声音文件的值

Question

我有如下一段代码：

.h

 #import <UIKit/UIKit.h>


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


  }
  return self;
 }


@end

好的，看起来很简单。只是一个带有图像的框架。图像获得值 +1。但我无法弄清楚如何使用声音文件来做到这一点。我想要 "link up" 图像和相关的声音文件。文件有编号，例如front1,front2... soundless 有 sound1, sound2...

感谢帮助！

编辑：类似于

self.audioplayer = [[AVAudioPlayer alloc] initWithContentsOfURL:[[NSURL   alloc] initFileURLWithPath: [[NSBundle mainBundle]     pathForResource:@"sfx%ld.wav", (long) (value+1)] error:NULL];

不起作用

Answer 1

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];

Answer 2

尝试关注

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];

Answer 3

-(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;
}

我想我必须说点什么，比如触摸按钮之类的？还是音频播放器从 initwithframe 继承了它？
