在应用中打开一个UIImagePickerController
对象。代码:
self.imgPicker = [[UIImagePickerController alloc] init];
self.imgPicker.delegate = self;
self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
self.imgPicker.modalPresentationStyle = UIModalPresentationFullScreen;
[self presentViewController:self.imgPicker animated:YES completion:nil];
然后应用就崩溃了:
Terminating app due to uncaught exception 'UIApplicationInvalidInterfaceOrientation', reason:
'preferredInterfaceOrientationForPresentation must return a supported interface orientation!'
我在ViewController 类中添加了下面的方法:
- (BOOL) shouldAutorotate
{
return NO;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)toInterfaceOrientation {
return UIInterfaceOrientationMaskPortrait;
}
谢谢
