- [UITextField isFirstResponder]返回false，即使字段当前正在编辑 [英] -[UITextField isFirstResponder] returns false even though field is currently editing

问题描述

在我的视图控制器的 -viewDidLoad 方法，我调用 [myTextField becomeFirstResponder]; 打开键盘和myTextField获取焦点。

In my view controller's -viewDidLoad method, I call [myTextField becomeFirstResponder]; This works like a charm, opens the keyboard and myTextField gets focus.

我有一个带有目标操作的按钮（操作在同一个控制器中），检查 [myTextField isFirstReponder] - 但它总是返回false（∈， NO 在Cocoa术语;））。

I have a button with a target action (the action is in the same controller) that checks [myTextField isFirstReponder] - but it always returns false (er, NO in Cocoa terms ;)).

这不是正确的方法来找出 myTextField 是否有键盘输入？

Is that not the right way to find out if myTextField has the keyboard up for input?

推荐答案

如何检查编辑属性的值，例如[myTextField isEditing]？

What about checking the value of the editing property, ie [myTextField isEditing]?

我认为你的按钮接管第一响应者状态当您点击它。

I think your button takes over first responder status when you tap it.
