我正在尝试将uiview添加到键盘顶部.我首先使用KeyboardWillShow/Hide完成了它,但它并未涵盖所有情况,我正在尝试使用inputAccesoryView.这是我试过的:

private var accessoryView = UIView(frame: CGRectZero)

class ViewController : UIViewController {

var myView: customUIView

override var inputAccessoryView: UIView {
    return accessoryView
}

override func canBecomeFirstResponder() -> Bool {
    return true
}

override func viewDidLoad() {
   super.viewDidLoad()
   accessoryView = myView
}
}

我收到以下错误:由于未捕获的异常'UIViewControllerHierarchyInconsistency'终止应用程序,原因:'子视图控制器:UICompatibilityInputViewController应该有父视图控制器:MyViewController但请求父级是:UIInputWindowController:'

任何帮助将不胜感激!

当我在ios8崩溃中运行时,我在选择器上方创建了一个带有两个按钮的工具栏并在ios7上工作:

终止应用程序2到未捕获的异常'UIViewControllerHierarchyInconsistency',原因:'子视图控制器:应该有父视图控制器:但是请求的父级是:'

这是在ios7中安静工作的代码段:

 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, 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 = …

我有一个消息应用程序.我UITabeView在ViewController中有一个.我在我的Custom上实现了我的longPressGesture事件,UITableViewCell以便在其上显示UIMenuController(copy-forward和...):

AudioMsgCell

-(void)handleLongPress:(UIGestureRecognizer *)gesture
        [self becomeFirstResponder]; // i crash on this Line
        UIMenuController *menu = [UIMenuController sharedMenuController];
        UIMenuItem *delete = [[UIMenuItem alloc] initWithTitle:@"Delete" action:@selector(Delete:)];
        CGRect targetRect = [self convertRect:[self.bubbleImageView frame]
                                     fromView:self];
        [menu setMenuItems:[NSArray arrayWithObjects:delete,nil]];
        [menu setTargetRect:targetRect inView:self];
        [menu setMenuVisible:YES animated:YES];}

我有一个UIMenuControllerinclude XIB file&some UITextField和myviewController我UIButton查看.

TextingViewController

 [self.view addSubview:self.inputView];

当我在单元格上长按手势时,我会在方法上崩溃

AudioMsgCell

 [self becomeFirstResponder]

我以前遇到过这个问题,当我在iOS 8中实现了额外的键盘时,但现在当我在我的Cell应用程序上做手势时出现此错误:

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: 0x14459d620> should have parent view controller:<BLTextingViewController: …

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.

应用程序在IOS 6上崩溃 - UIViewControllerHierarchyInconsistency

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 * …

我的故事板视图中有一个UIDatePicker连接到头文件中的IBOutlet.

在实现文件中,我将一些属性设置为选择器,然后将其分配给我的textFields:

[self.txtEndDate setInputView:self.picker];

这在iOS 7中运行良好,但是对于iOS 8,它给出了以下错误:

Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason: 'child view controller:<UICompatibilityInputViewController: 0x7c2d8800> should have parent view controller:<InserimentoDurata: 0x7aec2b10> but requested parent is:<UIInputWindowController: 0x7b92b400>'

有关如何解决此问题的任何想法？

我有UITextView一个UIView.当viewLoad,我有一个UIPickerView内UIAlertView有"OK"按钮.当我从选择器中选择任何值并单击"确定"时,我需要激活UITextView.
为此我写了[<myTextView> becomeFirstResponder];委托方法UITextView.只要此方法执行它textViewShouldBeginEditing,就会调用委托方法.这个方法正确执行,我在这里返回TRUE,但之后执行返回到该行[<myTextView> becomeFirstResponder];,然后应用程序崩溃.
UIAlertView委托方法如下:

- (void)customIOS7dialogButtonTouchUpInside: (CustomIOS7AlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex
{
    NSLog(@"Button at position %d is clicked on alertView %d.", (int)buttonIndex, (int)[alertView tag]);
    [alertView close];
    [self.updateTV becomeFirstResponder];
}

在上面的代码应用程序崩溃[self.updateTV becomeFirstResponder];
崩溃日志显示如下:
