Multiple PickerViews in one View?

Question

I want to create 2 separate pickers in the same view using the same viewController. But how do I set separate delegates and datasource for them?

Can\'t seem to get i

The most straight forward way to do this is to use the tag property of the pickerView. I usually define these in the header for readability. You can set the tag in Interface Builder or in code.

#define kPickerOne 0
#define kPickerTwo 1

Then in your implementation file...

-(NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView 
{
     if(pickerView.tag == kPickerOne)
     {
          // do something with picker one
     }
     else if(pickerView.tag == kPickerTwo)
     {
          // the other picker
     }
}
