UIViewControllerHierarchyInconsistency仅在iOS 8和Xcode 6中崩溃应用程序

概述我有一个在iOS 7和 Xcode 5中运行良好的应用程序.当我将其更新到iOS 8和Xcode 6时,当应用程序尝试在轻触textField时在视图中向上滑动UIDatePicker时,它会崩溃. 我正在使用故事板. 有谁知道为什么？ 我已经阅读了这个,但它的Xib.

解决方法 您可以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 dateNSDateFormatter *dateFormatter = [[NSDateFormatter alloc] init];// the specific format to usedateFormatter.dateFormat = @"dd-MMM-yyyy";// converting string to dateNSDate *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];
