iPad顯示popover中選定的圖片

Question

在研究了關於UIImagePickerController後，我得到了這段代碼從popover中選擇一個圖像，然後將其顯示在myParticularImageView中。

這個ViewController.m：

@interface ViewController() { 
UIImagePickerController *imagePickerController; 
UIPopoverController *popover; 
} 
@end 

- (IBAction)chooseImageButtonPressed:(id)sender { 

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; 
popover = [[UIPopoverController alloc] initWithContentViewController:imagePicker]; 
[popover setDelegate:self]; 
[popover presentPopoverFromRect:((UIButton *)sender).frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 
} 

//then to dismiss the popover and display pic 
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 

UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage]; 
[[self myParticularImageView] setImage:image]; 
[popover dismissPopoverAnimated:YES]; 
} 
@end 

我的問題是，當我在PIC挖掘從酥料餅沒有任何反應。

在.H我：

:UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIPopoverControllerDelegate> 

什麼可能導致我的問題，我該如何解決呢？

你不是圖像挑選者委託，這就是爲什麼你沒有觸及委託方法。

在創建時需要添加：[imagePicker setDelegate:self];。
