  UIButton *button = view.subviews[0];
  if (button) {
//自己设定颜色
   button.backgroundColor = RGBACOLOR(255, 102, 64, 1);
//这个字符串的长度控制了删除按钮的宽度
   [button setTitle:@"      " forState:UIControlStateNormal];
//背景图什么的
   [button setImage:[UIImage imageNamed:@"deleteAddress"] forState:UIControlStateNormal];
  }
 }
