[KSXYSwitchView showInView:self.view images:@[@"person_info.png", @"make_call.png", @"make_audio_call.png", @"make_video_call.png"] atPoint:point buttonClicked:^(NSInteger index) {
        if(index == 0) {
            NSLog(@"Click person button index = %ld", (long)index);
        } 
        else if(index == 1) {
            NSLog(@"Click call button index = %ld", (long)index);
        } 
        else if(index == 2) {
            NSLog(@"Click audio call button index = %ld", (long)index);
        } 
        else if(index == 3) {
            NSLog(@"Click video call button index = %ld", (long)index);
        }
}];
