How to distuingish between UIImagePickerController in didFinishPickingMediaWithInfo

Question

I have two UIImageViews in which I want to load two different images. I have two buttons which triggers a UIImagePickerController and calls my

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

method.

Is there a way to distinguish from which picker the method above is called?

Answer 1

You can make an instance of UIButton

@interface YourClass ()
{
   UIButton *_selectedButton;
}

and before triggering UIImagePickerController, you can save the button in the instance variable

-(void)button1Clicked:(UIButton *)button1{
      _selectedButton = button1;
     // call UIImagePickerController
} 

-(void)button2Clicked:(UIButton *)button2{
      _selectedButton = button2;
      // call UIImagePickerController
} 


- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{   
      if (_selectedButton == button1){
         // perform your logic 
      } else if (_selectedButton == button2){
        // perform your logic 
      }
}
