所以我有大约 7 个文本字段，其中 6 个使用键盘，另一个使用选择器。我遇到的问题是，如果在触摸链接到选择器的文本字段时打开键盘，则键盘不会关闭并且选择器会出现在其下方。这是我的代码
- (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;
