在PopOverController中添加UIButton - Xcode

Question

我有一个应用程序，其底部有一个工具栏，其中一个选项为Upload。点击它后，会出现一个PopOverController，显示可供选择的照片列表。

选择照片后，我想显示一个视图（在PopOverController本身内），其中包含照片以及名为Upload的按钮。在选择我的照片时，目前我的PopOverController没有被解雇。我已经使用了以下几行代码：

-(IBAction)photolibrarypressed:(id)sender{ 
    NSLog(@"hi"); 

    UIImagePickerController *picker= [[UIImagePickerController alloc] init]; 
    picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; 
    picker.delegate = self; 

    UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:picker]; 
    self.popoverController = popover;   
    popoverController.delegate = self; 
    [popoverController presentPopoverFromBarButtonItem:sender permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; 

    imageView = [[UIImageView alloc] initWithFrame:[window bounds]]; 


    [window addSubview:imageView]; 
    imageView.hidden = YES; 
    [window makeKeyAndVisible];  
} 

- (void)imagePickerController:(UIImagePickerController *)picker 
    didFinishPickingImage:(UIImage *)image 
       editingInfo:(NSDictionary *)editingInfo 
{ 
    imageView.image = image;  
    NSLog(@"hellow"); 
    [self dismissModalViewControllerAnimated:YES]; 

    // need to show the upload image button now 
    upload.hidden = NO; 
} 

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker 
{ 
    [picker dismissModalViewControllerAnimated:YES]; 
    exit(0); 
} 

有人可以帮我解决这个问题吗？

与其说

[self dismissModalViewControllerAnimated:YES]; 

调用相同的取消方法，INT EH取消方法来处理驳回它的模式的看法

[picker dismissModalViewControllerAnimated:YES]; // Dismisses modalView
