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];
最佳答案
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。
