Multiple UITextFields with UIPicker and UIKeyboard - iphone

Question

So I have about 7 textfields and 6 of them use a keyboard and the other uses a picker. The problem I'm having is that if the keyboard is open when the textfield that is linked to the picker is touched the keyboard won't dismiss and the picker appears under it. Here's my code
- (void) textFieldDidBeginEditing:(UITextField *)textField
{
pickerView.hidden = YES;
if ([textField isEqual:state])
{
[state resignFirstResponder];
[self textFieldFirstResponderOnDelay1];
}
else
{
pickerView.hidden = YES;
// This movie the view up so textfield isn't hidden by keyboard
CGRect textFieldRect =
[self.view.window convertRect:textField.bounds fromView:textField];
CGRect viewRect =
[self.view.window convertRect:self.view.bounds fromView:self.view];
CGFloat midline = textFieldRect.origin.y + 0.5 * textFieldRect.size.height;
CGFloat numerator =
midline - viewRect.origin.y
- MINIMUM_SCROLL_FRACTION * viewRect.size.height;
CGFloat denominator =
(MAXIMUM_SCROLL_FRACTION - MINIMUM_SCROLL_FRACTION)
* viewRect.size.height;
CGFloat heightFraction = numerator / denominator;
if (heightFraction < 0.0)
{
heightFraction = 0.0;
}
else if (heightFraction > 1.0)
{
heightFraction = 1.0;
}
UIInterfaceOrientation orientation =
[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait ||
orientation == UIInterfaceOrientationPortraitUpsideDown)
{
animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
}
else
{
animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
}
CGRect viewFrame = self.view.frame;
viewFrame.origin.y -= animatedDistance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
}
-(void) viewDidLoad
{
pickerView = [[UIPickerView alloc] init];
pickerView.frame = CGRectMake(0, 245, 320, 216);
pickerView.delegate = self;
pickerView.hidden = YES;
pickerView.showsSelectionIndicator = YES;
state.inputView = pickerView;
[self.view addSubview:pickerView];
}
-(void)textFieldFirstResponderOnDelay1
{
pickerView.hidden=NO;
[pickerView reloadAllComponents];
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
if([textField isEqual:state])
{
}
else
{
CGRect viewFrame = self.view.frame;
viewFrame.origin.y += animatedDistance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
}

Instead of adding the pickerview as a subview of your main window, just set it as the input view for the appropriate textviews, then it will show/hide as the keyboard would normally:
textField.inputView = pickerView;
