iOS开发——技术精华Swift篇&Swift 2.0和Objective－C2.0混编之第三方框架的使用
swift 语言是苹果公司在2014年的WWDC大会上发布的全新的编程语言。Swift语言继承了C语言以及Objective-C的特性，且克服了C语言的兼容性问题。Swift语言采用安全编程模式，且引入了多种新功能，使得编程工作更加简便，灵活！
2015年6月9日苹果又一次给所有开发之者带来了一个惊喜，那就是今年年底swift讲开源，者队iOS开发着来说无疑是一个值得兴奋的消息，可是就在这短短的几个月里面swift吸引了越来越多的开发者去学习，不仅仅是iOS开发者。
然而，在我们学习和使用swift的时候遇到一个最大的问题就是，之前在使用Objective－C开发iOS程序的时候，有大量的框架可以使用，或者是工具类什么的，而且有些功能实现起来很简单（虽然swift实现也不难），导致开发者不知所错，这个时候苹果的一个非常好的技术就非常有用了（虽然这个技术也是很早就出来了，基本上随着swift1.0出来的，但是那个时候还不够完善），那就是混编，其实就是在swift中编写OC代码，或者在OC中编写swift代码（这种方法很少有人用）。
混编是一个很神奇的技术，这里就不多介绍内在含义了，下面我们就来看看在swift怎么编写Objective－C代码：
首先，在下面这篇文章中我已经介绍什么怎么为混编做准备（就是关于桥接文件的配置），如果你还不知道去做那么就先看看再来开始接下来的精彩时刻！

1:MJRefresh（小码哥出品，质量优保障，哈哈）：一个集成下拉刷新和上啦加载更多的非常有名的第三方库
1 self.tableView.addLegendHeaderWithRefreshingTarget(self, refreshingAction: "headRefresh") 2 3 self.tableView.addGifFooterWithRefreshingTarget(self, refreshingAction: "footRefresh")
实现相应的监听方法
1 func headRefresh(){
2
3 self.Delay(2, closure: { () -> () in
4
5 self.ObjectArray.removeAll(keepCapacity: false)
6
7 self.i = 0
8
9 for self.i ; self.i < 10 ; self.i++ {
10
11 self.ObjectArray.append("\(self.i)")
12
13 }
14
15 self.tableView.header.endRefreshing()
16
17 self.tableView.reloadData()
18
19 })
20
21 }
22
23 func footRefresh(){
24
25 self.Delay(2, closure: { () -> () in
26
27 var j = self.i + 10
28
29 for self.i ; self.i < j ; self.i++ {
30
31 self.ObjectArray.append("\(self.i)")
32
33 }
34
35 self.tableView.footer.endRefreshing()
36
37 self.tableView.reloadData()
38
39 })
40
41 }
42
43 func Delay(time:Double,closure:()->()){
44
45 dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(time * Double(NSEC_PER_SEC))), dispatch_get_main_queue(), closure)
46
47 }
2:ProgressHUD：指示器
1 ProgressHUD.show("亲爱的，别急嘛～～～")
2
3
4
5 ProgressHUD.showSuccess("人家准备好了！")

3:PathCover ：主页风格
1 var head:XHPathCover!
2
3
4
5 head = XHPathCover(frame: CGRectMake(0, 0, 320, 200))
6
7 head.setBackgroundImage(UIImage(named: "BG"))
8
9 head.setAvatarImage(UIImage(named: "cute_girl.jpg"))
10
11 head.isZoomingEffect = true;
12
13 head.setInfo(NSDictionary(objectsAndKeys: "StrongX",XHUserNameKey,"iOS工程师",XHBirthdayKey)as [NSObject:AnyObject])
14
15 head.avatarButton.layer.cornerRadius = 33;
16
17 head.avatarButton.layer.masksToBounds = true
18
19 head.handleRefreshEvent = {
20
21 self.headRefresh()
22
23 }
24
25 tableView.tableHeaderView = head;
26
27
28
29 func scrollViewDidScroll(scrollView: UIScrollView) {
30
31 head.scrollViewDidScroll(scrollView)
32
33 }
34
35 func scrollViewDidEndDecelerating(scrollView: UIScrollView) {
36
37 head.scrollViewDidEndDecelerating(scrollView)
38
39 }
40
41 func scrollViewDidEndDragging(scrollView: UIScrollView, willDecelerate decelerate: Bool) {
42
43 head.scrollViewDidEndDragging(scrollView, willDecelerate: decelerate)
44
45 }
46
47 func scrollViewWillBeginDragging(scrollView: UIScrollView) {
48
49 head.scrollViewWillBeginDragging(scrollView)
50
51 }
4:SDWebImage：图片缓存
1 SDImageCache.sharedImageCache().clearDisk() 2 3 SDImageCache.sharedImageCache().clearMemory() 4 5 6 7 var image = UIImageView(frame: CGRectMake(10, 10, 60, 60)) 8 9 image.layer.cornerRadius = 30 10 11 image.layer.masksToBounds = true 12 13 image.sd_setImageWithURL(NSURL(string: "http://ac-hn8w3hlp.clouddn.com/fVju6pA4WGzVGNGsVdVXEzB.png"), placeholderImage: UIImage(named: "cute_girl.jpg")) 14 15 cell.contentView.addSubview(image)
5:拓展Extension（可以相当于OC中的分类）：
1 extension UIView {
2
3 func sayHello(){
4
5 println("哈喽，大家好，欢迎l来到iOS梦工厂”)
6
7 }
8
