使用UIKeyCommand时如何处理大小写字符

Question

We are in the process of receiving and processing keyboard input.

Among my source code,

UIKeyCommand *menuKey = [UIKeyCommand keyCommandWithInput:[NSString stringWithFormat:@"%c", 77]
                                                modifierFlags:0
                                                       action:@selector(menuKey:)];

There is this part.

However, if you process it like this, it will only react when it is an uppercase 'M', and it does not respond when it is a lowercase 'm'.

Is there a way to handle UIKeyCommand with all uppercase and lowercase characters?

Answer 1

您可以为大写字母和小写字母添加命令

Answer 2

The reason is that you only look for 77 which is ASCII code for M . In order to allow m , you need to add 109 as well
