UIpicker array with changing values

I'm making an app that uses the picker to let the user pick age and few other inputs. for eg: i have a button age, when the user clicks it, the picker shows the age. i managed to add individual picker for all the inputs, how ever i'm having problems setting different arrays for each picker. 

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { 
    if (pickerview == picker) {
        return [pickerViewArray objectAtIndex:row];
    }
    else if (pickerview == stagepicker)
        return [stagepickerarray objectAtInde:row];
    }
}

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {
    if (thePickerView == picker){ return [pickerViewArray count]; }
    else if (thePickerView == stagepicker){ [stagepickerarray count]; }
}

the above method isn't working for me !. Am I doing this right ?

Solution 
  • - (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component { 
    if (pickerview == picker) {

    Doesn't it sound like pickerview should be written thePickerView instead?

    return [stagepickerarray objectAtInde:row];

    Doesn't it sound like objectAtInde should be objectAtIndex?

    else if (thePickerView == stagepicker){ [stagepickerarray count]; }

    Doesn't it sound like a return is missing somewhere?
