Question

我想要使尺寸为UIPopoverController等于IPad屏幕的两个方向。怎么做？

Answer 1

CGRect popoverRect = [self.view convertRect:[btn frame] 
            fromView:[btn superview]]; 

popoverRect.size.width = self.view.frame.size.width; 
popoverRect.origin.x = popoverRect.origin.x+150; 
popoverRect.size.height = self.view.frame.size.width; 
[self.popoverController 
presentPopoverFromRect:popoverRect 
inView:self.view 
permittedArrowDirections:UIPopoverArrowDirectionLeft 
animated:YES]; 

Answer 2

- (void)viewDidAppear:(BOOL)animated { 
[super viewDidAppear:animated]; 
self.contentSizeForViewInPopover = CGSizeMake(width,height);}
