IOS 8: - [UIInputViewSet setRestorableResponder:]:发送到解除分配的实例0x7d6659b0的消息

Question

这只发生在IOS 8 iPhone应用程序中,该应用程序与以前的版本一起工作正常.来到这个问题,我有一个表视图,其中包含文本字段和其他单元格.textfield的所有代表都已实现.现在,当我点击文本字段时,会显示键盘.当键盘仍然可见时,我点击另一个单元格,将我带到其他视图,解除键盘.现在,当我点击这个新视图中的后退按钮返回上一个视图时,应用程序崩溃,显示标题中提到的错误消息.这曾经在IOS 7和之前的版本中完美运行.请帮忙.

按要求添加堆栈跟踪.

Answer 1

我遇到了类似的问题,是的,事实证明文本字段已被解除分配.我通过在推送新视图控制器之前添加对endEditing的调用来修复它在我的代码中:

[self.view endEditing:YES];
[self.navigationController pushViewController:...
                                     animated:YES];
