Scroll the scrollview up when pickerview comes up

Question

I have a form that I put inside a scrollview. On this form I have a couple of buttons that puts up a dateTime picker or a pickerView when I press on them. But I was wondering if I can but my form up to show the text that at the moment is behind the pickerView.

I know you can do that with a UITextfield. You can find the explanation over here .

Hope that anyone can help me!

Kind regards!

Answer 1

-(IBAction)btnDate_Clicked:(id)sender
{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    yourScrollView.frame = CGRectMake(0, -100, 320, yourScrollView.frame.size.height);  // set frame which you want   
    [UIView commitAnimations];


}

and when you want to set original position of scroll then again set the scrollview frame with my animation code for ex.

-(IBAction)btnDone_Clicked:(id)sender
{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    yourScrollView.frame = CGRectMake(0, 0, 320, yourScrollView.frame.size.height);  // set frame which you want   
    [UIView commitAnimations];


}

使用UIScrollView的scrollRectToVisible:animated:方法
