Question

我有以下代码：

·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，看起来很容易。只是一个带图像的框架。图像获得+1值。但我无法弄明白如何使用声音文件。我想“链接”图像和相关的声音文件。文件有数字，例如front1，front2 ......和无声有sound1，sound2 ......

感谢您的帮助！

编辑：类似

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

尝试以下

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;
}

我想我必须说点按钮或其他东西？或音频播放器是否从initwithframe继承？

如何增加声音文件的值，如uiimagefile
