问题
I've a modal view controller that I show with UIModalPresentationPageSheet. The problem is that his default size is too large for my content: so I want to resize is frame to adjust in according with my content.
Does anyone know a way/trick to do this ?
Thanks
回答1:
You can't resize a UIModalPresentationPageSheet because its size is not modifable.

Actually you can resize the view controller that gets presented with UIModalPresentationPageSheet. To do it you need to create a custom view controller class and add the following to the class:
<!--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;
}
And then you display this view controller with a UIModalPresentationPageSheet. And that's it. This does work for iOS 5.1.1 and iOS 6 as of the date of this post.

This works for resizing a view controller that's presented as UIModalPresentationFormSheet
. I would give this a try, I'm not sure if it'll work or not:
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;
