I have UIView, I want to add it a view on that view but so it be half of the size of the original View.
I tried :
[appDelegate.viewController presentModalViewController:testViewController animated:NO];
but itws on all the screen.
tried:
self.window.frame= CGRectMake(50, 50, 30, 30);
self.frame= CGRectMake(50, 50, 30, 30)
I saw there is methods like presentPopupViewController but they work on UIViewcontroller.
any ideas to start it on half of the screen?
该消息presentModalViewController:animated:将以模态方式呈现视图，始终占据整个屏幕。它不会将视图添加到您当前的视图中。
为此，请使用UIView's message addSubview:。您可以根据需要调整子视图的大小。
使用 presentModalViewController:animated: 无法调整大小。
要产生像 presentModalViewController:animated: 这样的效果，请使用 CATransition：
CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setType:kCATransitionMoveIn];
[animation setSubtype:kCATransitionFromBottom];
[animation setDuration:0.50];
[animation setTimingFunction:
[CAMediaTimingFunction functionWithName:
kCAMediaTimingFunctionEaseInEaseOut]];
[self.view.layer addAnimation:animation forKey:kCATransition];
现在在 self.view 中添加视图，如下所示：
[self.view addSubView:testViewController.view];
[testViewController.view setFrame:CGRectMake((self.view.frame.size.width/4),(self.view.frame.size.height/4),(self.view.frame.size.width*3/4),(self.view.frame.size.height*3/4))];
假设您有两个视图，一个是mainview第二个是childview。
在主视图上添加子视图
[mainview addSubview:childview];
从主视图中删除子视图
[childview removeFromSuperview];
但是如果你想要一些动画而不是你必须为此添加一些额外的代码。
