    NSDictionary *dict=@{(__bridge NSString *)kAXTrustedCheckOptionPrompt:@YES};
    BOOL istrue=AXIsProcessTrustedWithOptions((__bridge CFDictionaryRef)dict);
    NSLog(@"%d",istrue);

方法1 cocoa

[NSEvent addGlobalMonitorForEventsMatchingMask:NSRightMouseDownMask|NSKeyDownMask|NSFlagsChanged handler:^(NSEvent * _Nonnull event) {
        if (event.type==NSKeyDown){
            NSLog(@"event %@",event.characters);
        }
    }];
