当我使用此代码进行弹出窗口创建时，它在初始化后给出 sigabrt 错误带有视图控制器的 UIPopoverController（测试2），

Test2 *pop=[[Test2 alloc]initWithNibName:@"Test2" bundle:nil];
popUpnew=[[UIPopoverController alloc] initWithContentViewController:pop];
popUpnew.delegate=self;
popUpnew.delegate=self;
popUpnew.popoverContentSize=CGSizeMake(150,75);
[popUpnew presentPopoverFromRect:mybutton.frame inView:self.view    permittedArrowDirections:
UIPopoverArrowDirectionAny animated:YES];

UIPopoverController with a view controller(Test2),

Test2 *pop=[[Test2 alloc]initWithNibName:@"Test2" bundle:nil];
popUpnew=[[UIPopoverController alloc] initWithContentViewController:pop];

你这里的看起来不错。您是否检查过 mybutton.frame 和 self.view 是否有效？调用presentPopoverFromRect后立即释放了吗？

您是否尝试过通过将委托设置为零来进行测试？

试试这个

Test2 *pop = [[Test2 alloc] initWithNibName:@"Test2" bundle:nil];
pop.modalPresentationStyle = UIModalPresentationFormSheet;
pop.modalInPopover=YES;
pop.delegate=self;
pop.contentSizeForViewInPopover=CGSizeMake(150,75);
popoverController = [[UIPopoverController alloc] initWithContentViewController:pop];
[popoverController presentPopoverFromRect:mybutton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop release];

Try this

Test2 *pop = [[Test2 alloc] initWithNibName:@"Test2" bundle:nil];
pop.modalPresentationStyle = UIModalPresentationFormSheet;
pop.modalInPopover=YES;
pop.delegate=self;
pop.contentSizeForViewInPopover=CGSizeMake(150,75);
popoverController = [[UIPopoverController alloc] initWithContentViewController:pop];
[popoverController presentPopoverFromRect:mybutton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
[pop release];
