ios - 在iPad上的Popover中推送导航 View Controller 时，更改Popover Controller 的大小

我是ios开发的新手，我有一个主viewController包含导航项，而我点击导航项popover viewcontroller看起来很好并且gettig准确的contentSize对于Popover中的View(320,845)，问题是当我点击popover viewcontroller popover中的按钮Contentsize有被改变。

UIBarButtonItem *btn = (UIBarButtonItem *)sender;
Agamam *agamamView = [[Agamam alloc] initWithNibName:@"Agamam" bundle:nil];
agamamView.delegate=self;
agamamView.contentSizeForViewInPopover  =CGSizeMake(agamamView.view.frame.size.width, agamamView.view.frame.size.height);

UINavigationController *navController =  [[UINavigationController alloc] initWithRootViewController:agamamView];
popAgamamView = [[UIPopoverController alloc] initWithContentViewController:navController];
[popAgamamView presentPopoverFromBarButtonItem:btn permittedArrowDirections:YES animated:YES];

最佳答案

试试这个....

- (void)viewWillAppear:(BOOL)animated
{
   CGSize size = CGSizeMake(320, 845); // size of view in popover
   self.contentSizeForViewInPopover = size;
   [super viewWillAppear:animated];
}
