在一個視圖中的兩個ImagePickerControllers

我在我的應用程序中有兩個圖像選擇器。我做了第一個正確的。用戶可以從庫中選擇或捕獲照片並在視圖中查看。但是當我嘗試複製代碼並粘貼它並更改動作和對象名稱時，我在兩行中出現錯誤。在一個視圖中的兩個ImagePickerControllers

-(IBAction)TakePhoto { 

    picker = [[UIImagePickerController alloc] init]; 
    picker.delegate = self; 
    [picker setSourceType:UIImagePickerControllerSourceTypeCamera]; 
    [self presentViewController:picker animated:YES completion:NULL]; 

} 

-(IBAction)ChooseExisting 

{ 
    picker2 = [[UIImagePickerController alloc] init]; 
    picker2.delegate = self; 
    [picker2 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
    [self presentViewController:picker2 animated:YES completion:NULL]; 

} 

-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 

{ 
    image = [info objectForKey:UIImagePickerControllerOriginalImage]; 
    [imageView setImage:image]; 
    [self dismissViewControllerAnimated:YES completion:NULL]; 
} 
-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker { 

    [self dismissViewControllerAnimated:YES completion:NULL]; 
} 

//the following part is the renamed part 


-(IBAction)TakePhoto2 { 

picker3 = [[UIImagePickerController alloc] init]; 
picker3.delegate = self; 
[picker3 setSourceType:UIImagePickerControllerSourceTypeCamera]; 
[self presentViewController:picker3 animated:YES completion:NULL]; 

} 

-(IBAction)ChooseExisting2 

{ 
picker4 = [[UIImagePickerController alloc] init]; 
picker4.delegate = self; 
[picker4 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[self presentViewController:picker4 animated:YES completion:NULL]; 
    } 
ERROR HERE !!-(void) imagePickerController:(UIImagePickerController *)picker3 didFinishPickingMediaWithInfo:(NSDictionary *)info 

{ 
    image2 = [info objectForKey:UIImagePickerControllerOriginalImage]; 
    [imageView2 setImage:image2]; 
    [self dismissViewControllerAnimated:YES completion:NULL]; 
} 
ERROR HERE !!!-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker3 { 

    [self dismissViewControllerAnimated:YES completion:NULL]; 
}

兩個「（無效）」 S我得到這個錯誤：重複的方法ImagePickerControllerDidcancel和ImagePickerControllerdidFinishPickingMediaWithINfo

的聲明這將是巨大的，如果你能爲我解決的代碼。由於

感謝您的幫助，我很抱歉，如果我的英語不夠好

-(void) imagePickerController:(UIImagePickerController *)picker3 didFinishPickingMediaWithInfo:(NSDictionary *)info; 

-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker3;

以上無一不是UIImagePickerController代表。

他們必須在控制器類中只出現一次。

注：更改參數名稱（S）不改變方法聲明。

您必須使用，如果這些方法裏面的語句來找出哪些選擇器被稱爲（'如果（拾取== self.picker1）'）或類似的東西。 – mrosales

你能更具體我沒有足夠的發展知識。 –
