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

实现图表之后的必备的三步曲

标签：Legend

 1   LineData2.dataTitle = "iCocos"
 2
 3         LineData.dataTitle = "iOS"
 4
 5         LineChart.legendStyle = PNLegendItemStyle.Serial
 6
 7
 8
 9         var legend = LineChart.getLegendWithMaxWidth(320)
10
11         legend.frame = CGRectMake(0, 320, 320, 100)
12
13         self.view.addSubview(legend)
14
15  

更新：Updata

 1  var dataArray3 = [3,6,8,12,5]
 2
 3         var LineData3 = PNLineChartData()
 4
 5         LineData3.color = UIColor.blueColor()
 6
 7         LineData3.itemCount = (UInt)(dataArray3.count)
 8
 9         LineData3.getData = ({(index:UInt)->PNLineChartDataItem in
10
11             var y:CGFloat = (CGFloat)(dataArray3[(Int)(index)])
12
13             return PNLineChartDataItem(y: y)
14
15         })
16
17         LineData3.dataTitle = "iCocos"
18
19         LineChart.updateChartData(LineData3, LineData)
20
21         LineChart.strokeChart()
22
23
24
25         var legend2 = LineChart.getLegendWithMaxWidth(320)
26
27         legend.frame = CGRectMake(0, 300, 320, 100)
28
29         self.view.addSubview(legend)

回调：Callback

 1 LineChart.delegate = self
 2
 3
 4
 5
 6
 7
 8
 9     /**
10
11     * Callback method that gets invoked when the user taps on the chart line.
12
13     */
14
15     - (void)userClickedOnLinePoint:(CGPoint)point lineIndex:(NSInteger)lineIndex
16
17     {
18
19         //实现数据刷新的代码
20
21     }
22
23
24
25     /**
26
27     * Callback method that gets invoked when the user taps on a chart line key point.
28
29     */
30
31     - (void)userClickedOnLineKeyPoint:(CGPoint)point
32
33     lineIndex:(NSInteger)lineIndex
34
35     pointIndex:(NSInteger)pointIndex{
36
37         //实现数据刷新的代码
38
39
40
41     }

14:AFN

 1 let afn = AFHTTPRequestOperationManager()
 2
 3 afn.GET("http://www.baidu.com", parameters: nil, success: { (oper, data) -> Void in
 4
 5     print(data)
 6
 7 }) { (opeation, error) -> Void in
 8
 9     print(error)
10
11 }

关于网络请求的，AFN作者为神马提供了一个通AFN一样好用的框架Alamofire

1 https://api.500px.com/v1/photos").responseJSON() {
2
3   (_, _, data, _) in
4
5   println(data)

总结：

好了，终于简单粗暴的的总结了一些了，后面笔者会更加深入的学习并且研究相关技术，花更多的时间进行分享相关技术并且优化，因为目前来说使用swift开发app混编时必须会的。
