今天下午呢_{简单的写了一个登录界面}如图:

中间的那三个按钮我是用for循环创建的(适配看起来有点墨迹- =凑活看吧~),代码如下:

        /**
          * 三个button
          * AppWidth: CGFloat = UIScreen.mainScreen().bounds.size.width
          * AppHeight: CGFloat = UIScreen.mainScreen().bounds.size.height
          */
        for index in 0 ..< 3  {
            //按钮
            let shareBtn = UIButton.init(frame: CGRectMake((AppWidth / 3) * CGFloat(index) + AppWidth / 3 / 3, 20, AppWidth / 3 / 3, AppWidth / 3 / 3))

            //图片名需要拼接下
            let imageStr = "share_"
            let imageName = imageStr + String(index)
            shareBtn.setImage(UIImage.init(named: imageName), forState: UIControlState.Normal)

            //我是先创建了一个backView把button都放在上面了, 方便适配
            backView.addSubview(shareBtn)
            
            //图片下的文字
            let shareLabel = UILabel.init(frame: CGRectMake((AppWidth / 3) * CGFloat(index) + AppWidth / 3 / 3, 30 + shareBtn.frame.size.height, shareBtn.frame.size.width, 10))
            shareLabel.textAlignment = NSTextAlignment.Center
            shareLabel.font = UIFont.systemFontOfSize(10)
            shareLabel.adjustsFontSizeToFitWidth = true

            //分别设置图片下文字和点击方法
           switch index {
            case 0:
                shareLabel.text = "微信登录"
                shareBtn.addTarget(self, action: #selector(tapped1), forControlEvents: UIControlEvents.TouchUpInside)
            case 1:
                shareLabel.text = "微博登录"
                shareBtn.addTarget(self, action: #selector(tapped2), forControlEvents: UIControlEvents.TouchUpInside)

            default:
                shareLabel.text = "QQ 登录"
                shareBtn.addTarget(self, action: #selector(tapped3), forControlEvents: UIControlEvents.TouchUpInside)

            }

我把图片的名字都改成顺序的, 比较方便创建

按钮点击事件响应:

func tapped1() {
        print("111")
    }

    func tapped2() {
        print("222")
    }
    
    func tapped3() {
        print("333")
    }

0.0啊_{就是这样啦}我觉得还挺方便的_{要是有什么更方便的方法希望能指教下哈}~
