请帮助谢谢
我的代码:
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
//set picker color start
[self.myDatePicker setBackgroundColor:[UIColor greenColor]];
//set picker color finish
//calculate bounds start
CGRect textFieldRect = [self.view.window convertRect:textField.bounds fromView:textField];
CGRect viewRect = [self.view.window convertRect:self.view.bounds fromView:self.view];
//calculate bounds finish
//calculate the fraction between the top and bottom of the middle section for the text field's midline start
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;
//calculate the fraction between the top and bottom of the middle section for the text field's midline finish
//Clamp this fraction so that the top section is all "0.0" and the bottom section is all "1.0 start
if (heightFraction < 0.0)
{
heightFraction = 0.0;
}
else if (heightFraction > 1.0)
{
heightFraction = 1.0;
}
//Clamp this fraction so that the top section is all "0.0" and the bottom section is all "1.0 finish
/*start
Now take this fraction and convert it into an amount to scroll by multiplying by the keyboard height for the current screen orientation. Notice the calls to floor so that we only scroll by whole pixel amounts */
UIInterfaceOrientation orientation =
[[UIApplication sharedApplication] statusBarOrientation];
if (orientation == UIInterfaceOrientationPortrait ||
orientation == UIInterfaceOrientationPortraitUpsideDown)
{
animatedDistance = floor(PORTRAIT_KEYBOARD_HEIGHT * heightFraction);
}
else
{
animatedDistance = floor(LANDSCAPE_KEYBOARD_HEIGHT * heightFraction);
}
//finish
//Finally, apply the animation start
CGRect viewFrame = self.view.frame;
viewFrame.origin.y -= animatedDistance;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationDuration:KEYBOARD_ANIMATION_DURATION];
[self.view addSubview:self.myDatePicker];
[self.view setFrame:viewFrame];
[UIView commitAnimations];
}
//Finally, apply the animation finish
//Animate back again start

-(void)viewDidLoad

self.myDatePicker = [[UIDatePicker alloc]init];
[self.myDatePicker setDatePickerMode:UIDatePickerModeCountDownTimer];
//to get text off picker
