UISegmentedControl

创建UISegmentedControl

let items = ["选项一","选项二","选项三"]
let segmented = UISegmentedControl(items: items)
segmented.frame = CGRectMake(40, 20, 300, 35)
self.view.addSubview

设置

segmented.selectedSegmentIndex = 0//默认选择第一项
segmented.addTarget(self, action: "segmentDidChange:", forControlEvents: UIControlEvents.ValueChanged)
segmented.setEnabled(false, forSegmentAtIndex: 1)//变灰无法选择

func segmentDidChange(segmented: UISegmentedControl){
    print(segmented.selectedSegmentIndex)
    if (segmented.titleForSegmentAtIndex(segmented.selectedSegmentIndex) != nil){//选项名称
        print(segmented.titleForSegmentAtIndex(segmented.selectedSegmentIndex)!)
    }
//        segmented.setContentOffset(CGSizeMake(5, 5), forSegmentAtIndex: segmented.selectedSegmentIndex)//修改选项内容偏移位置
}

选项的添加和删除

segmented.insertSegmentWithTitle("新增选项", atIndex: 1, animated: true)//添加新的选项
segmented.insertSegmentWithImage(UIImage(named: "00000"), atIndex: 2, animated: true)
segmented.removeSegmentAtIndex(2, animated: false)//删除选项卡
segmented.setTitle("swift", forSegmentAtIndex: 1)//修改选项文字
