UIImagePicker总是在iOS 5中发布imagePickerControllerDidCancel

Question

因此，我重新测试了一个我知道在iOS 4.2以及新iOS 5中使用的应用程序，并且出于某种原因，他们不想玩得很好。我的UIImagePicker代理将在用户从照片库中选择一张照片时，总是发出一个imagePickerControllerDidCancel，并且决不允许图片被选中（只是说当我尝试加载时图像是零）。这是我知道的以前iOS版本的代码，所以我不知道为什么现在不行，除非Apple改变了UIImagePicker的工作方式。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage : (UIImage *)image editingInfo:(NSDictionary *)editingInfo 
{ 
mainPhoto.image = image; 
[self saveImage:image]; 
[picker dismissModalViewControllerAnimated:YES]; 
} 

-(void)imagePickerControllerDidCancel:(UIImagePickerController *) picker 
{ 
[picker dismissModalViewControllerAnimated:YES]; 
} 

这里是调用UIImagePicker代码：

UIImagePickerController * picker = [[UIImagePickerController alloc] init]; 
picker.delegate = self; 
picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum; 
[self presentModalViewController:picker animated:YES]; 
[picker release]; 

任何想法？还是有其他人有这个问题？为
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage : (UIImage *)image editingInfo:(NSDictionary *)editingInfo

文件说，

“弃用iOS中使用3.0 imagePickerController：didFinishPickingMediaWithInfo：代替”。尝试遵循的建议，让我们知道，如果你仍然面临的问题？
