大佬教程收集整理的这篇文章主要介绍了UIViewControllerHierarchyInconsistency仅在iOS 8和Xcode 6中崩溃应用程序，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我已经阅读了这个,但它的Xib.
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

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.从Xib
[self.DatePickerView removeFromSuperview]; [Textfield seTinputView:self.DatePickerView]; [Textfield seTinputView:self.DatePickerView];
