I have a dilemma, I have two UIPickerViews which \"show\" when two distinct views load. I started with one UIPickerView and was able to get that up and running

Yeah you are, you have to use the UIPickerView argument to determine WHICH picker view is actually asking for data - since you have set both pickers to the same data source.

-(void)numberOfComponentInPickerView:(UIPickerView*)thePickerView {
    if(thePickerView == firstPickerView) {
       // return number of components in first picker    
    } else if(thePickerView == secondPickerView) {    
       // return number of components in second picker    
    } else {
       assert(NO);
    }
}

// repeat for all other delegate / datasource methods
