Question

I have a view that has 5 UITextFields that brings up one instance of a UIPickerView. The problem is that the selector indicator wants to always start at the array position that the previous text field left off. For example I have 2 arrays 1 cat, dog, horse and 2house, barn, school. If i select the first text field and select dog, when I click the second text field the indicator view starts at barn. Currently I just have it set to animate to position 0 of each array, but is there a way that I can have them each start at the 0 position in the array and then save the position of each array using the one instance of the UIPicker? Thanks!

edit: sorry, my syntax prevent some of my question from showing

Answer 1

Use two int iVar for saving indexes of picker while selecting row from picker.

int a,b;
BOOL isArray1IsUsedInPicker;

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    if(isArray1IsUsedInPicker)
       a=row;
    else
       b=row;
}

and when you reload the picker according to your array, adjust BOOL variable accordingly

- (void)textFieldDidBeginEditing:(UITextField *)textField
    {
       // your code ---
        // set  isArray1IsUsedInPicker = YES; if going to use array1 else set NO 

        [picker reloadComponent];

       if(isArray1IsUsedInPicker)
          [picker selectRow:a inComponent:0 animated:NO];
       else
          [picker selectRow:b inComponent:0 animated:NO];

     }
