cocoa - Button with keyboard input via Input Method Kit

Question

I am creating a virtual keyboard for my application via Input Method Kit (IMK).

However I am not able to simulate a keyboard event by pressing a button.

Is there any library I can used for keyboard event simulation?

Are there any reference materials/solutions for this problem?

请参阅IMKTextInput 协议参考，您需要调用insertText:replacementRange:

[client insertText:text replacementRange:NSMakeRange(NSNotFound, NSNotFound)];

text的实例在哪里NSString。
