的UIImagePickerController didFinishPickingMediaWithInfo不会被调用

我在与使用的UIImagePickerController麻烦。基本上，虽然正在显示拾取精细，的UIImagePickerController didFinishPickingMediaWithInfo方法是拒绝被称为（我试过NSLogging一路走过，它只是不会被调用）。这里是我的代码（我已经在头文件中定义imgPicker为的UIImagePickerController）：的UIImagePickerController didFinishPickingMediaWithInfo不会被调用

-(IBAction)grabImage { 
    self.imgPicker = [[UIImagePickerController alloc] init]; 
    self.imgPicker.allowsImageEditing = YES; 
    self.imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    [self presentModalViewController:self.imgPicker animated:YES]; 
} 

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 
    imgview.image = [info objectForKey:UIImagePickerControllerEditedImage]; 
    [[picker parentViewController] dismissModalViewControllerAnimated:YES]; 
}

任何人有任何想法，为什么它没有被叫什么名字？

是否已经设置的UIImagePickerController委托财产，如果不这样做如下

myImagePickerController.delegate = self;

还与UIImagePickerControllerDelegate协议确认，

谢谢，成功了！虽然我得到这个错误（这似乎没有影响任何东西）：class'myClass'没有实现'UINavigationControllerDelegate'协议。我假设有没有实现UIImagePickerControllerDelegate协议有关，但我不知道如何做到这一点。 PS：请原谅我的newbieness。：p – 2011-03-31 08:44:54
