ios - Popover 在 iPhone 中崩溃

Question

我正在为 iPad 应用程序的弹出窗口使用以下代码。它适用于 iPad 应用程序，但当我对 iPhone 使用相同的代码时，它会崩溃

" UIPopoverController* removeDefaultPopover=[[UIPopoverController alloc]initWithContentViewController:NavController];"

任何人都可以帮助我摆脱困境..

 UIViewController  *removeDefaultController = [[UIViewController alloc] init];
        UIView *removeDefaultView = [[UIView alloc] init];
        removeDefaultController.view = removeDefaultView;

        removeDefaultController.contentSizeForViewInPopover = CGSizeMake(100, 100);
        UINavigationController *NavController=[[UINavigationController alloc]initWithRootViewController:removeDefaultController];
        UIPopoverController* removeDefaultPopover=[[UIPopoverController alloc]initWithContentViewController:NavController];
        UIBarButtonItem *edit = [[UIBarButtonItem alloc] initWithTitle:@"EDIT" style:UIBarButtonItemStyleBordered target:self action:@selector(editDefaultLanguage)];
        [removeDefaultController.navigationItem setRightBarButtonItem:edit animated:YES];removeDefaultPopover.delegate=self;
        [removeDefaultPopover presentPopoverFromRect:CGRectMake(0, 0, 100, 100) inView:self.view permittedArrowDirections:NO animated:YES];
        removeDefaultView.backgroundColor=[UIColor redColor];

来自documentation :

Popover controllers are for use exclusively on iPad devices. Attempting to create one on other devices results in an exception.

您必须自己实现类似的功能。
