奇异位置下的UIAlertController呈现

Question

每当我试图提出这个警告，它总是出现在某个奇怪的地方。有什么办法解决这个问题吗？

屏幕截图

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"Logout"
                                                                       message:@"Are you sure you want to logout?"
                                                                preferredStyle:UIAlertControllerStyleAlert];


[alert addAction:[UIAlertAction actionWithTitle:@"Yes"
                                 style:UIAlertActionStyleDestructive
         handler:^(UIAlertAction * _Nonnull action) {

             [[NSUserDefaults standardUserDefaults] setBool:@"NO" forKey:@"auth"];
             [(AppDelegate *)[UIApplication sharedApplication].delegate changeRootViewController:[Login sharedLogin]];

         }]];

[alert addAction:[UIAlertAction actionWithTitle:@"No"
                                                  style:UIAlertActionStyleCancel
                                                handler:^(UIAlertAction * _Nonnull action) {
                                                    [alert dismissViewControllerAnimated:YES completion:nil];
                                                }]];
[self presentViewController:alert animated:YES completion:nil];

我想你把窗框改成了两倍宽和高，所以它显示在那里。你可以把这个记录下来看看。
