is there a uipickerview delegate method like scrollviewDidScroll?

Question

I have a customized UIPickerview and I do not want to use a datepicker. I want to implement the feature where when a user scrolls down/up the hours, the AM/PM component swi

Answer 1

have to use this two UIPickerView delegate method for event:

DID END SCROLL:

- (void)pickerView:(UIPickerView *)pV didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
    NSLog(@"pickerView didSelectRow %zd",row);
    // DID END SCROLL: CALL YOUR HEANDLER METHOD!!
}

WILL START SCROLLING:

- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
    // WILL START SCROLLING: CALL YOUR HEANDLER METHOD!!
    UILabel* label = (UILabel*)view;
    if (!label){
        label = [UILabel new];
        [label setFrame:frame];
        [label setBackgroundColor:[UIColor clearColor]];
        [label setFont:[UIFont fontWithName:FONT_QUICKSAND_BOLD size:12]];
        [label setTextAlignment:NSTextAlignmentRight];
        [label setLineBreakMode:NSLineBreakByTruncatingMiddle];
        [label setTextColor:UIColorFromRGB(0X2692ff)];
        }
    //Update labeltext here
    [label setText:[NSString stringWithFormat:@"row %zd",row]];
    return label;
}

obviosly except for the building of UIPickerview (firstTIME!); so u have to implement a fake didendscroll event when you finish to build you piker or ignore first willstart scroll for the visible piker row
