Answer 1

Rayfleck走上正轨。

如果您想要在视图中的某个位置关闭键盘，请使用以下＆amp;让iOS处理响应者链

[self.view endEditing:YES];

当视图中有表格并且表格到处都有文本字段时，这非常有用。

来自Apple Doc：

- (BOOL)endEditing:(BOOL)force

描述导致视图（或其中一个嵌入的文本字段）重新签署第一个响应者状态。此方法查看当前第一个响应者的文本字段的当前视图及其子视图层次结构。如果找到一个，则要求该文本字段作为第一响应者辞职。如果force参数设置为YES，则永远不会询问文本字段;它被迫辞职。参数
力
指定YES以强制第一响应者辞职，无论是否要这样做。返回如果视图重新调整了第一响应者状态，则为YES;如果视图没有，则为NO。

Answer 2

我遇到了与UITextField完全相同的问题。当我更换

[myTextField resignFirstResponder];

与

[myTextField endEditing:YES];

撞车停了。

UIResponder（静态）_setFirstResponder：休息
