Answer 1

这是UIImagePickerControllerDelegate的类定义：

@protocol UIImagePickerControllerDelegate<NSObject>
@optional
// The picker does not dismiss itself; the client dismisses it in these callbacks.
// The delegate will receive one or the other, but not both, depending whether the user
// confirms or cancels.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_NA,__MAC_NA,__IPHONE_2_0,__IPHONE_3_0);
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info;
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker;

@end

我认为上面提到的一种方法是您需要的：

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker;

将UitabbarController的SelectedViewController属性设置为要切换到的视图控制器。将新视图控制器分配给此属性更改当前显示的视图，并在选项卡栏中选择适当的选项卡。
