我想让“Next”按钮执行 segue 以移动到“PersonalInformation”(一个 UIViewController)
但是我得到一个带有代码的“SIGABRT 信号”.. 我该如何解决？
let alert = UIAlertController(title:"Confirmation", message: confirmationMessage, preferredStyle: UIAlertControllerStyle.Alert)
let confirmBtn : UIAlertAction = UIAlertAction(title: "Next", style: UIAlertActionStyle.Default, handler: {(action:UIAlertAction!)-> Void in
self.performSegueWithIdentifier("PersonalInformation", sender: self)
})
let cancelBtn : UIAlertAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.Cancel, handler: nil)
alert.addAction(cancelBtn)
alert.addAction(confirmBtn)
self.presentViewController(alert, animated: true, completion: nil)
