    if (event == UIControlEventValueChanged) {
        self.delegate = target;
        self.action = action;
    }
}
@end

具体使用步骤:

//添加控件
HeadView *headView = [[HeadView alloc]initWithFrame:CGRectMake(0, 0, DEF_SCREEN_WIDTH, 44)];
    headView.titleArray = @[@"未完成",@"已完成"];
    headView.selectedIndex = self.currentIndex;//设置默认选择项索引
    headView.tint_Color = [UIColor lightGrayColor];
    [headView addTarget:self action:@selector(didclickHeadview:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:headView];

#pragma mark - Event
-(void)didclickHeadview:(HeadView *)headview {
 
    NSLog(@"%s---%zd",__func__,headview.selectedIndex);
    
}
