UIAlertController在关闭WiFi时出错

let networkIssueController = UIAlertController(title: "Error",
                                               message: "Unable to load data. Connectivity error!", 
                                               preferredStyle: .Alert)
let okButton = UIAlertAction(title: "Ok", style: .Default, handler: nil)
networkIssueController.addAction(okButton)
let cancelButton = UIAlertAction(title: "Cancel", style: .Cancel, handler: nil)
networkIssueController.addAction(cancelButton)
self.presentViewController(networkIssueController, animated: true, completion: nil)

错误显示为EXC_BAD_ACCESS(code=1,address=0x10)

导致此错误的原因是什么？

Answer 1

尝试添加单独的alertView实例。

Answer 2

这是一个简单的警报视图，这非常有效。试试这个。

let alertController = UIAlertController(title: "Warning", message: "Test", preferredStyle: UIAlertControllerStyle.Alert)
        let cancel = UIAlertAction(title: "OK", style: UIAlertActionStyle.Cancel, handler: nil)

        alertController.addAction(cancel)

        self.presentViewController(alertController, animated: true, completion: nil)
