如何在iPhone上禁用键盘点击声音？

Question

How do we disable the keyboard tap sound programatically? I am sure it's a setting in UItextfield.

Answer 1

The closest thing I was able to find is how to subclass particular views to disable sound:

Can I disable UIPickerView scroll sound?

I can't test this at work, but if it is possible, this may be related. UIKeyboard is a class that you can't actually subclass though, nor even declare. You can find an actual reference to it though via the following method:

Also, in the UIKeyboardImpl header file, I do see the setSoundsEnabled method:

Answer 2

You cannot change this value. It's a user preference and only controllable through the Settings App.
