iphone - 如何调整 UIModalPresentationFormSheet 的大小？

Question

我正在尝试将模态视图 Controller 显示为 UIPresentationFormSheet。 View 出现了，但我似乎无法调整它的大小。我的 XIB 具有适当的高度和宽度，但是当我这样调用它时，它似乎被覆盖了:

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

有什么想法吗？我正在使用 iPhone SDK 3.2 beta 4

您可以在展示模态视图后调整它的框架:

在 iOS 5.1 - 7.1 中测试

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];
}
