Question

I am opening UIPickerView on UIButton click and i am calling commit animation on UIPickerView by this UIPikerView opens like a keyboard from bottom to mid of screen i want to scroll up the view when picker view shows because of buttons by which i calling the UIPickerView is hide by UIPikerView when it is open. So how can i auto scroll the view when picker view is open?

Answer 1

You can use this to scroll the main view up and scroll down main view

- (void)scrollUpView {
    CGFloat kMoveRatio = 50.0f // Change to view the buttons
    [UIView beginAnimations:@"UP" context:nil];
    CGRect aVFrame = self.view.frame;
    [self.view setFrame:CGRectMake(aVFrame.origin.x, aVFrame.origin.y - kMoveRatio, aVFrame.size.width, aVFrame.size.height)];
    [UIView commitAnimations];

}

-(void)scrollDownView
{
    [UIView beginAnimations:@"DOWN" context:nil];
    CGRect aVFrame = self.view.frame;
    [self.view setFrame:CGRectMake(aVFrame.origin.x, 0, aVFrame.size.width, aVFrame.size.height)];
    [UIView commitAnimations];
}
