如何调整UIModalPresentationFormSheet的大小？

问题描述

我试图显示一个模态视图控制器作为UIPresentationFormSheet。视图出现，但我似乎无法调整它的大小。我的XIB有适当的高度&宽度，但是当我这样调用它似乎被覆盖：

  composeTweetController = [[ComposeTweet alloc] initWithNibName：@ ComposeTweetbundle：nil]; 
 composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet; 
 [self presentModalViewController：composeTweetController animated：TRUE]; 
  

有任何想法吗？我使用的是iPhone SDK 3.2 beta 4

解决方案

显示模式视图后，你可以调整框架： / p>

在iOS 5.1 - 7.1版测试

  MyModalViewController * targetController = [[[MyModalViewController alloc] init] autorelease]; 
 targetController.modalPresentationStyle = UIModalPresentationFormSheet; 
 targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizo​​ntal; // transition should not matter 
 [self presentViewController：targetController animated：YES completion：nil]; 
 
 if（floor（NSFoundationVersionNumber）< = NSFoundationVersionNumber_iOS_6_1）{
 targetController.view.superview.frame = CGRectInset（targetController.view.superview.frame，100，50）; 
} else {
 targetController.view.frame = CGRectInset（targetController.view.frame，100，50）; 
 targetController.view.superview.backgroundColor = [UIColor clearColor]; 
} 
  

I am trying to display a modal view controller as a UIPresentationFormSheet. The view appears, but I can't seem to resize it. My XIB has the proper height & width, but it seems to get overridden when I call it like this:

composeTweetController = [[ComposeTweet alloc] initWithNibName:@"ComposeTweet" bundle:nil];
composeTweetController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:composeTweetController animated:TRUE];

Any thoughts? I am using the iPhone SDK 3.2 beta 4

解决方案

You are able to adjust the frame of a modal view after presenting it:

Tested in iOS 5.1 - 7.1

MyModalViewController *targetController = [[[MyModalViewController alloc] init] autorelease];
targetController.modalPresentationStyle = UIModalPresentationFormSheet;
targetController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;  //transition shouldn't matter
[self presentViewController:targetController animated:YES completion:nil];

if(floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1){
     targetController.view.superview.frame = CGRectInset(targetController.view.superview.frame, 100, 50);
}else{
     targetController.view.frame = CGRectInset(targetController.view.frame, 100, 50);
     targetController.view.superview.backgroundColor = [UIColor clearColor];
}
