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

segment.selectedSegmentIndex = 0
segment.addTarget(self, action: "click:", forControlEvents: UIControlEvents.ValueChanged)
self.navigationItem.titleView = segment
//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(width: (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

let normalFont = UIFont(name: "Helvetica", size: 16.0)
let normalTextAttributes: [NSObject : AnyObject] = [
NSForegroundColorAttributeName: UIColor.blackColor(),
NSFontAttributeName: normalFont!
]
let selctedTextAttributes: [NSObject : AnyObject] = [
NSForegroundColorAttributeName: UIColor.redColor(),
NSFontAttributeName: normalFont!
]
segment.setTitleTextAttributes(normalTextAttributes, forState: .Normal)
segment.setTitleTextAttributes(selctedTextAttributes, forState: .Selected)
//获取某一个下标下的标题

let titleT = segment.titleForSegmentAtIndex(0)
print(titleT)
//获取某一个下表下的图片

let image = segment.imageForSegmentAtIndex(3)
print(image)
//设置下标为2的分段的宽度为80

segment.setWidth(80, forSegmentAtIndex: 2)
//获取某一个下标segment的宽度

let width = segment.widthForSegmentAtIndex(2)
print(width)
