我有一个在 iOS 7 和 Xcode 5 中运行良好的应用程序。当我将它更新到 iOS 8 和 Xcode 6 时，当应用程序试图在点击文本字段时在 View 中向上滑动 UIDatePicker 时，它崩溃了。 我正在使用 Storyboard。 有人知道为什么吗？
我已经阅读过这篇文章，但它是针对 Xib 的。
App crashes on IOS 6 - UIViewControllerHierarchyInconsistency
请帮忙 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

最佳答案
以编程方式创建日期选择器，或者如果您将其用作拖入组件，请执行以下给定步骤
1.以编程方式创建
datePicker = [[UIDatePicker alloc]init];
[datePicker setDate:[NSDate date]];
//NSString *maxDateString = @"01-Jan-2012";
NSString *theMinimumDate = @"01-Jan-1976";
// the date formatter used to convert string to date
NSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];
// the specific format to use
dateFormatter.dateFormat = @"dd-MMM-yyyy";
// converting string to date
NSDate *theMaximumDate = [NSDate date];//[dateFormatter dateFromString: maxDateString];
NSDate *theminimumDate = [dateFormatter dateFromString: theMinimumDate];
// repeat the same logic for theMinimumDate if needed
// here you can assign the max and min dates to your datePicker
[datePicker setMaximumDate:theMaximumDate];//the max age restriction (if needed, or else dont use this line)
[datePicker setMinimumDate:theminimumDate]; //the min age restriction
// set the mode
[datePicker setDatePickerMode:UIDatePickerModeDate];
// Do any additional setup after loading the view from its nib.
[datePicker addTarget:self action:@selector(updateTextField:) forControlEvents:UIControlEventValueChanged];
// and finally set the datePicker as the input mode of your textfield
[Textfield setInputView:datePicker];
2.来自Xib
[self.DatePickerView removeFromSuperview];
[Textfield setInputView:self.DatePickerView];
[Textfield setInputView:self.DatePickerView];
