NSInteralInconsistencyException – UIKeyboardLayoutAlignmentView

我在报告中遇到了跟踪崩溃，但我不知道从哪里开始寻找！ – 任何帮助表示赞赏。 我没有调用或引用到UIKeyboardLayoutAlignmentView

Fatal Exception: NSInternalInconsistencyException The layout constraints still need update after sending -updateConstraints to <_UIKeyboardLayoutAlignmentView: 0x14df2550; frame = (0 0; 0 0); userInteractionEnabled = NO; layer = <CALayer: 0x1603de90>>. _UIKeyboardLayoutAlignmentView or one of its superclasses may have overridden -updateConstraints without calling super. Or, something may have dirtied layout constraints in the middle of updating them. Both are programming errors.

Answer 1

好的，问题发现一个固定的。 在iOS8.3上，如果您正在显示键盘，然后尝试显示具有input字段的UIAlertView或UIAlertController，则会发生此故障。

简单的解决scheme（对我来说）是插入

 [self.window endEditing:YES]; 

要么

 [self.view endEditing:YES]; 

在任何这样做的警报面前，它不再崩溃

更新

在某些情况下，我还需要下面一行（如下面Oren所述），endEditing和这一行我没有问题 – 但是有一个或另一个我已经看到奇怪的崩溃，这是奇怪的 – 但组合攻击似乎上class ！

 UITextField *txtEmail = [alertView textFieldAtIndex:0]; [txtEmail becomeFirstResponder]; 

Answer 2

这显然是在显示键盘时显示UIAlertView或UIAlertController时iOS8.3的一个错误。

解决方法是将警报视图的文本字段分配为第一个响应者。 这比通过resignFirstResponder或endEditing隐藏键盘更好，因为键盘不会闪烁。

 UIAlertView *alertView = [[UIAlertView alloc] initWithTitle....... alertView.alertViewStyle = UIAlertViewStylePlainTextInput; UITextField *txtEmail = [alertView textFieldAtIndex:0]; [txtEmail becomeFirstResponder]; [alertView show]; 

Answer 3

这可能会帮助有同样问题的人。 我来这里查看你的答案，但是这对我没有用。

iOS 8.3 UIAlertController在尝试添加文本字段时崩溃

为了重申另一个线程上的内容，我通过在呈现UIAlertController时将animation标志设置为“NO”来解决这个问题

 [self presentViewController:alert animated:NO completion:nil]; 

Answer 4

在Ionic应用程序中使用Cordova对话框插件时遇到了同样的问题。 看起来像iOS8.3每当一个通知或警报被调用，键盘已经可见，它会尝试打开另一个导致崩溃的键盘。 我将这一行添加到插件中的CDVNotification.m文件中。

  if ([dialogType isEqualToString:DIALOG_TYPE_PROMPT]) { alertView.alertViewStyle = UIAlertViewStylePlainTextInput; UITextField* textField = [alertView textFieldAtIndex:0]; **[textField becomeFirstResponder];** //added this line to Fix :) textField.text = defaultText; }
