Xcode:如何创建出现在另一个视图控制器中的PopUp视图控制器

Question

基本上我想要弄清楚的是,我说有一个名为V1的视图控制器,里面有一个常规视图和一个按钮.现在,当您点击该按钮时,我希望该按钮创建一个动作,在同一视图控制器V1中弹出另一个名为V2的视图控制器.

V2的大小会减小一些,以至于它不会填满整个屏幕,但你仍然可以看到V2后面的第一层是V1.所以基本上,你永远不会离开V1.我希望这对我正在尝试做的事情有意义.我知道MTV应用程序具有这种功能.我正在谈论的图片如下:https://docs.google.com/leaf？id = 0BzlCAVXRsIPcNWUxODM2MDAtNDE3OS00ZTc4LTk5N2MtZDA3NjFlM2IzNmZk&hl = en_US

示例代码或示例也是我正在寻找的.

谢谢

Answer 1

您可以通过设置适当的属性类型来创建此类视图modalPresentationStyle.请参阅下面的示例:

UIViewController *V2 = [[UIViewController alloc] init];
V2.modalPresentationStyle = UIModalPresentationFormSheet;
V2.modalTransitionStyle = UIModalTransitionStyleCoverVertical;     
[V1 presentViewController:V2 animated:YES completion:nil];
V2.view.superview.frame = CGRectMake(0, 0, 540, 620); //it's important to do this after presentModalViewController
V2.view.superview.center = V1.view.center;
[V1 release];

Answer 2

试试这个:

V2 *d = [[V2 alloc]initWithNibName:@"V2" bundle:nil];//assuming V2 is name of your nib as well
d.delegate = self; //Optional:you only need this if you want to delegate

 //create popover and put V2 in the popover view
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:d]; 
popoverController.delegate = self;  //optional
CGSize size = CGSizeMake(325, 75); // size of view in popover…V2
popoverController.popoverContentSize = size;
[d release];
[popoverController presentPopoverFromRect:yourButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
