我有一个模态视图控制器,我用UIModalPresentationPageSheet显示。问题是他的默认大小对我的内容来说太大了:所以我想调整大小是根据我的内容进行调整。
有没有人知道这样做的方法/技巧?

实际上,您可以调整使用UIModalPresentationPageSheet呈现的视图控制器的大小。要做到这一点,您需要创建一个自定义视图控制器类并将以下内容添加到类中:
<!--The header file-->
@interface MyViewController: ViewController{
//Used to store the bounds of the viewController
CGRect realBounds;
}
<!--In the .m file-->
//viewDidLoad gets called before viewWillAppear, so we make our changes here
-(void)viewDidLoad{
//Here you can modify the new frame as you like. Multiply the
//values or add/subtract to change the size of the viewController.
CGRect newFrame = CGRectMake(self.view.frame.origin.x,
self.view.frame.origin.y,
self.view.frame.size.width,
self.view.frame.size.height);
[self.view setFrame:newFrame];
//Now the bounds have changed so we save them to be used later on
_realBounds = self.view.bounds;
[super viewDidLoad];
}
//viewWillAppear gets called after viewDidLoad so we use the changes
//implemented above here
-(void)viewWillAppear:(BOOL)animated{
//UIModalpresentationPageSheet is the superview and we change
//its bounds here to match the UIViewController view's bounds.
[super viewWillAppear:animated];
self.view.superview.bounds = realBounds;
}
然后使用UIModalPresentationPageSheet显示此视图控制器。就是这样。截至本文发布之日,这适用于iOS 5.1.1和iOS 6。

您无法调整UIModalPresentationFormSheet的大小,因为其大小不可修改。

这适用于调整显示为UIModalPresentationFormSheet
的视图控制器的大小。我会尝试一下,我不确定它是否会起作用:
navController.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:navController animated:YES];
//these two lines are if you want to make your view smaller than the standard modal view controller size
navController.view.superview.frame = CGRectMake(0, 0, 200, 200);
navController.view.superview.center = self.view.center;
