textView.becomefirstresponder（）和敲击文本视图之间的区别？
我有一个带有多个文本字段和一个文本视图的应用程序页面。 TextView类似于聊天应用程序上的消息栏。
当我点击消息文本视图框时，我编写的代码根据键盘高度调整视图。 但是，当我调用MessageTextView.becomefirstresponder（）时，视图不会使用键盘升高。
textView.becomefirstresponder（）和在TextView上敲击？
- 我已经测试过，并且可以看到提高视图的代码在调试器中调用。它只是不会在屏幕上执行。
- 我还测试了
I have an app page with multiple textfields and one textview.
The textview is similar to the message bar on chat apps.
When I tap the message textView box, the code I wrote adjusts the view according to the height of the keyboard.
But when I call messageTextView.becomeFirstResponder() instead, the view does not raise with the keyboard.
Is there a difference between textView.becomeFirstResponder() and just tapping on the textView?
- I have tested and can see that the code to raise the view is called in the debugger. it just don't execute on screen.
- I have also tested and see that becomeFirstResponder() is returning true
