} 

@IBAction func C4(_ sender: UIButton) {

    audioPlayerC4.play() 
} 

}

和我得到这个错误在该行

let pianoSoundC3 = Bundle.main.url(forResource: "DO1", withExtension: 
"mp3")! 

...........

<<<< exc_bad_instruction(code=exc_i386_invop subcode=0x0) 

此指令有吸收声音"DO1"带按钮pianoSoundC3

Answer 1

很可能您的捆绑包中没有资源名称DO1.mp3。

检查您是否在项目中添加了这样的资源并且路径是正确的。
