问题很奇怪。 当我给我的UIPopoverController增加一架UIImagePickerController时,通常在航标上显示的取消纽芬兰就不复存在。
我曾试图将UIImagePickerController降级,在航道上添加一条通.,但并未显示。
如果我选择我的照相机,后纽子就自动增加,但取消的纽特仍然下落不明。
任何人都知道这有什么原因?
这里是使用守则。 注:_popOver是我的UIPopoverController。
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
[_popOver setContentViewController:picker animated:YES];
我已尝试过这一法典,现在我认为它是一种违约行为。 UIImagePickerController通常作为模式观点控制员提出,Cancel hton的目的在于将其开除。 当你把UIImagePickerController带入UIPopover 主计长随后Cancel hton变得毫无意义。 否则,你就可以在任何地方挖掘(UIPopoverController除外)。 如果UIPopoverController将/did开除UIPopoverController 代表方法:
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController{
UIImagePickerController *imagePicker = (UIImagePickerController*)popoverController.contentViewController;
return YES;
}
