NSBundle PathForResource 返回nil的问题

NSString *cafPath = [[NSBundle mainBundle]pathForResource:@"selected" ofType:@"caf"]; NSString *wavPath = [[NSBundle mainBundle]pathForResource:@"button" ofType:@"wav"]; NSString *imagePath = [[NSBundle mainBundle]pathForResource:@"bug" ofType:@"png"]; NSLog@"%@",cafPath; NSLog@"%@",wavPath; NSLog@"%@",imagePath; 

我在工程的同一个目录下添加了三个文件,格式分别为caf,wav,png。我在输出的结果却是

null

也就是说第一个caf格式的音频没能读出来,这是什么问题啊,重点是同一个文件夹下啊!!!

xcode 傻逼的编译问题,clean 掉就ok了
