在PresentedViewController离开UIPopoverController时解雇UIPopoverController

Question

弹出的PresentedViewController，这是我正在使用的代码

SearchPropertyVC *SearchPropertyVC *centerViewController = (SearchPropertyVC *)[board instantiateViewControllerWithIdentifier:@"vcSearchPropertyID"];
UINavigationController *ConDetVC = [[UINavigationController alloc] initWithRootViewController:centerViewController];
ConDetVC.modalPresentationStyle = UIModalPresentationPageSheet;
ConDetVC.modalPresentationStyle = UIModalPresentationFormSheet;
ConDetVC.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;

[self presentViewController:ConDetVC animated:YES completion:nil];
ConDetVC.view.superview.bounds = CGRectMake(0, 0, 700, 670);

控制器打开的很好，当我试图关闭控制器时，我会收到这个警告

“警告:试图在演示文稿或解职过程中从视图控制器中解职！”！

之后，如果我点击任何按钮，应用程序就会崩溃。

这是我用来拒绝视图的代码

[self dismissViewControllerAnimated:YES completion:nil];

[self dismissViewControllerAnimated:YES completion:^{
             [(UINavigationController *)self.presentingViewController popToRootViewControllerAnimated:YES];
         }];

if (![self.presentedViewController isBeingDismissed])
            [self dismissViewControllerAnimated:YES completion:nil];

当我试图取消popover视图本身时，会得到相同的警告

Answer 1

在第一次修正以下线。

 SearchPropertyVC *SearchPropertyVC *centerViewController = (SearchPropertyVC *)[board instantiateViewControllerWithIdentifier:@"vcSearchPropertyID"];

 SearchPropertyVC *searchPropertyVC = (SearchPropertyVC *)[board instantiateViewControllerWithIdentifier:@"vcSearchPropertyID"];

选择任何一种表达方式，

 ConDetVC.modalPresentationStyle = UIModalPresentationPageSheet;
 ConDetVC.modalPresentationStyle = UIModalPresentationFormSheet;

页表或表单页。

当您尝试呈现时，请使用想要呈现的视图对象控制器。

 [self presentViewController:ConDetVC animated:YES completion:nil]; 

当它被驳回的时候，只需写信，

 [self dismissViewControllerAnimated:YES completion:^{
         // write you code here
     }];

这将帮助你：

 [self.presentedViewController dismissViewControllerAnimated: YES completion:^(void) {
             [self presentViewController:myController animated:YES completion:nil];
    }];
