objective-c - 如何在 iPad 上更改 UIImagePickerController 的大小宽度？

Question

如何在 iPad 上改变 UIImagePickerController 的大小宽度？我可以改变高度，所以它是 700，但不能改变宽度，它仍然是 320。我的代码。

 UIImagePickerController*  imagePicker=[[UIImagePickerController alloc]init];
 imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
 imagePicker.delegate=self;
 CGRect myRect = CGRectMake(imagePicker.view.frame.origin.x, imagePicker.view.frame.origin.y, 720, 700);
 imagePicker.view.frame = myRect;
 self.popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker];
 myRect = CGRectMake(100, 880, 900, 900);
 CGRect re2 = CGRectMake(0,0,800,800);
 [self.popover setPopoverContentSize:re2.size];
 [self.popover presentPopoverFromRect:[self.view bounds] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
 [self.popover presentPopoverFromRect:myRect inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];      
 [self.popover setPopoverContentSize:re2.size];

我遇到了同样的问题，我用 UINavigationControllerDelegate 解决了，因为 PhotoLibrary 的 UIImagePickerView 内容是一个 navigatorController。当您选择一行时，它会更改 ViewController 并且弹出窗口的大小也会更改。因此，在您的 willShowViewController 委托(delegate)中只需放置:

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
    viewController.contentSizeForViewInPopover = CGSizeMake(800, 800);
}

这将阻止调整弹出窗口的大小。
