添加键盘快捷键

Question

I want to make little app for my home. It should detect keyboard shortcut (for example: Cmd + C + 1 ) and send now selected text to my app (like automator service).

How can I do it? May be you can give tutorial link to me?

Answer 1

I think you are wanting an Automator Action . In Xcode create an Application Plug-in Automator Action and post a notification to the NSDistributedNotificationCenter

- (id)runWithInput:(id)input fromAction:(AMAction *)anAction error:(NSDictionary **)errorInfo
{
    NSDistributedNotificationCenter *dc = [NSDistributedNotificationCenter defaultCenter];
    [dc postNotificationName:@"aName" object:@"anObject"
                    userInfo:[NSDictionary dictionaryWithObject:input
                                                         forKey:@"aKey"]];
    return input;
}

You will need to implement an observer in your app

[[NSDistributedNotificationCenter defaultCenter] addObserver:self selector:@selector(aSelector:) name:@"aName" object:nil];

If you include the Automator Action bundle in your app ${BUILT_PRODUCTS_DIR}/${PRODUCT_NAME}.app/Contents/Library/Automator/ Automator should be able to find it.
