首先可以先下载一个dome

_shangchuan = [[UIButton alloc]init];
    _shangchuan.frame = CGRectMake(0, self.view.fream.size.height - 50, 100, 100);
    [_shangchuan setTitle:@"123" forState:UIControlStateNormal];
    [_shangchuan addTarget:self action:@selector(shangchuanBtn) forControlEvents:UIControlEventTouchUpInside];
    _shangchuan.backgroundColor = [UIColor redColor];
    [self.view addSubview:_shangchuan];
    
    _qingchu = [[UIButton alloc]init];
    _qingchu.frame = CGRectMake(150, self.view.fream.size.height - 50, 100, 100);
    [_qingchu setTitle:@"123" forState:UIControlStateNormal];
    _qingchu.backgroundColor = [UIColor redColor];
    [self.view addSubview:_qingchu];
    
    _yizhang = [[UIButton alloc]init];
    _yizhang.frame = CGRectMake(300, self.view.fream.size.height - 50, 100, 100);
    [_yizhang setTitle:@"123" forState:UIControlStateNormal];
   
    _yizhang.backgroundColor = [UIColor redColor];
    [self.view addSubview:_yizhang];
    
   
    

然后根据dome继续完善工程
