Question

我正在制作搜索系统。如果在文本字段中输入文本并且其值在数据库中，则它将转换到下一个屏幕并显示所获取的数据。在调试屏幕上，由于显示获取的值，我认为API正在运行。但是，我收到EXC_BAD_INSTRUCTION错误（代码= EXC_I386_INVOP，子代码= 0x0）这个错误导致我被困5个小时。请告诉我。谢谢。

}




override func viewDidLoad() {
    super.viewDidLoad()



}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

}

我有一个错误EXC_BAD_INSTRUCTION（代码= EXC_I386_INVOP，子代码= 0x0）
