ios – 由于未捕获的异常UIViewControllerHierarchyInconsistency终止应用程序,

概述我在两个按钮上创建了一个工具栏,并在ios7上运行,当我在ios8崩溃时运行： Terminating app two to uncaught exception ‘UIViewControllerHierarchyInconsistency’, reason: ‘child view controller: Should Have parent view controller: but requ 我在两个按钮上创建了一个工具栏,并在ios7上运行,当我在ios8崩溃时运行：

Terminating app two to uncaught exception
‘UIVIEwControllerHIErarchyInconsistency’,reason: ‘child vIEw
controller: Should
Have parent vIEw controller: but requested parent is: ‘

这是在ios7中静默工作的代码片段：

expiredPromoTextFIEld.inputVIEw = DatePicker; expiredPromoTextFIEld.delegate = self; quantityPromoTextFIEld.inputVIEw = quantityPicker; quantityPromoTextFIEld.delegate = self; // Create button to close the UIPickerVIEw UIToolbar * mypickerToolbar = [[UIToolbar alloc] initWithFrame: CGRectMake (0,320,56)]; mypickerToolbar.barStyle = UIbarStyleBlackTranslucent; [mypickerToolbar sizetoFit]; NSMutableArray * barItems = [[NSMutableArray alloc] init]; UIbarbuttonItem * CancelBtn = [[UIbarbuttonItem alloc] initWithbarbuttonSystemItem: UIbarbuttonSystemItemCancel target: self action:selector (cancelDoneClicked)]; [barItems addobject: CancelBtn]; UIbarbuttonItem * FLEXspace = [[UIbarbuttonItem alloc] initWithbarbuttonSystemItem: UIbarbuttonSystemItemFlexibleSpace target: self action: nil]; [barItems addobject: FLEXspace]; UIbarbuttonItem * doneBtn = [[UIbarbuttonItem alloc] initWithbarbuttonSystemItem: UIbarbuttonSystemItemDone target: self action:selector (pickerDoneClicked :)]; [barItems addobject: doneBtn]; [mypickerToolbar setItems: barItems animated: YES]; [quantityPicker setShowsSelectionIndicator: YES]; expiredPromoTextFIEld.inputAccessoryVIEw = mypickerToolbar; quantityPromoTextFIEld.inputAccessoryVIEw = mypickerToolbar;

你知道我的意思是inputAccessoryVIEw会崩溃的应用程序,我也问苹果的工程师,他们告诉我,这是测试版的一个问题,但现在与GM继续给同样的问题.

我该怎么办？

解决方法 我在iOS 8上也有同样的例外,现在修正为以下代码.

关键是,您不应该添加输入视图作为视图控制器视图的子视图.
(我不知道为什么iOS 7中的代码运行良好,在iOS 8中不再奏效)

之前(发生错误)

UITextFIEld* someTF;VIEw* customVIEw;UIVIEwController *mainVC;[mainVC.vIEw addSubvIEw:customVIEw];someTF.inputVIEw = customVIEw;

之后(工作良好)

UITextFIEld* someTF;VIEw* customVIEw;UIVIEwController *mainVC;//  [mainVC.vIEw addSubvIEw:customVIEw];  <-- delete this linesomeTF.inputVIEw = customVIEw;
