The desired effect is that when the keyboard appears, the buttons and labels at the bottom will automatically move up and be above the keyboard. When the keyboard disappears, the buttons and labels will automatically return to the bottom.

I use the method of adding scrollView and then monitor the status of the keyboard, but the problem I encounter is: when the keyboard disappears, the button and label are indeed at the bottom, but when the keyboard appears, the button and label will be replaced by the keyboard. Cover. Is there any way to solve this problem? Thank you
