当我启动该应用程序时,我看到一个白屏并告诉我该错误,我该如何解决?该行中显示错误:
![myLabel.alpha = 0]
错误是线程1:EXC_BAD_INSTRUCTION(代码= EXC_I386_INVOP,子代码0x0)
import UIKit
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
myLabel.alpha = 0
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
最佳答案
您的@IBOutlet必须已经无效。也许您在连接后或其他原因重命名了它。您应该删除现有的,然后重新创建。请检查my answer in other thread on how to do this。
