swift 学习之UISegmentedControl

//创建分段控件的标题

        let titileArray:[String] = ["点评", "哪里逃"]

        let segment = UISegmentedControl(items: titileArray)
        //默认选中下标

        //在坐标为2的位置插入一个分段图片
         segment.insertSegmentWithImage(UIImage(named: "car")!, atIndex: 2, animated: true)
        //在坐标为1 的位置插入一个分段标题
        segment.insertSegmentWithTitle("插入新", atIndex: 1, animated: true)
        let flowLayout = UICollectionViewFlowLayout()
        flowLayout.itemSize = CGSize( (Tools().SCREEN_WIDTH - 30) / 3, height: (Tools().SCREEN_WIDTH - 30) / 3)
        //清除segment的背景色
        segment.tintColor = UIColor.clearColor()
       
        //设置segment字体选中和非选中时的状态
