女神画廊App (Swift1.2)

这个App的是storyboard+code的结合，主要的重点是：

1.segue传递图片值。

2.Autolayout中可以使用右下角三角符号使用Add Missing Constraints进行大概约束，使之适应不同大小屏幕。

3.上边栏Editor -> Embed In -> Navigation Controller或者Tab Bar Controller。

4.实现分享功能。 

5.注意storyboard设计Navigation Controller界面时关于segue的modal类型要改为push类型。

6.按住Command点击某个Controller控件代码可显示其方法类。

storyboard设计界面：

目录结构：

ViewController.swift文件代码：

 1 import UIKit
 2 class ViewController: UIViewController {
 3 
 4     @IBOutlet weak var beautyPicker: UIPickerView!
 5     let beauties = ["范冰冰","李冰冰","王菲","杨幂","周迅"]
 6     override func viewDidLoad() {
 7         super.viewDidLoad()
 8         beautyPicker.dataSource = self
 9         beautyPicker.delegate = self
10     }
11     override func didReceiveMemoryWarning() {
12         super.didReceiveMemoryWarning()
13         // Dispose of any resources that can be recreated.
14     }
15     
16     override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
17         if segue.identifier == "GoToGallery"{
18             let index = beautyPicker.selectedRowInComponent(0)
19             var imageName:String?
20             switch index{
21             case 0:
22                 imageName = "fanbingbing"
23             case 1:
24                 imageName = "libingbing"
25             case 2:
26                 imageName = "wangfei"
27             case 3:
28                 imageName = "yangmi"
29             case 4:
30                 imageName = "zhouxun"
31             default:
32                 imageName = nil
33                 
34             }
35             var vc = segue.destinationViewController as! GalleryController
36             vc.imageName = imageName
37         }
38     }
39 }

View.swift (ViewController.swift的额外扩展文件)：

 1 import UIKit
 2 
 3 extension ViewController:UIPickerViewDataSource{
 4     // returns the number of 'columns' to display.
 5     func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int{
 6         return 1
 7     }
 8     // returns the # of rows in each component..
 9     func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
10         return beauties.count
11     }
12 }
13 extension ViewController:UIPickerViewDelegate{
14     func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String!{
15         return beauties[row]
16     }
17 }

GalleryController.swift文件代码：

 1 import UIKit
 2 import Social  3 
 4 class GalleryController: UIViewController {
 5     var imageName:String?
 6     
 7     @IBOutlet weak var beautyImage: UIImageView!
 8     override func viewDidLoad() {
 9         super.viewDidLoad()
10         /*if (imageName != nil){
11             beautyImage.image = UIImage(named: imageName!)//修改前
12         }*/
13         
14         if let name = imageName {
15             beautyImage.image = UIImage(named: name)
16             switch name{
17             case "fanbingbing":
18                 navigationItem.title = "范冰冰"
19             case "libingbing":
20                 navigationItem.title = "李冰冰"
21             case "wangfei":
22                 navigationItem.title = "王菲"
23             case "yangmi":
24                 navigationItem.title = "杨幂"
25             case "zhouxun":
26                 navigationItem.title = "周迅"
27             default:
28                 navigationItem.title = "女神画廊"
29             }
30         }
31     }
32     override func didReceiveMemoryWarning() {
33         super.didReceiveMemoryWarning()
34         // Dispose of any resources that can be recreated.
35     }
36     
37  //分享按钮 38  @IBAction func shareTapped(sender: AnyObject) { 39  var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTencentWeibo) 40  controller.setInitialText("一起来玩女神画廊app吧，就在Github上") 41  controller.addImage(beautyImage.image) 42  self.presentViewController(controller, animated: true, completion: nil) 43  } 44 }

KoreanViewController文件代码：

 1 import UIKit
 2 import Social  3 class KoreanViewController: UIViewController {
 4     @IBOutlet weak var beautyImage: UIImageView!
 5     override func viewDidLoad() {
 6         super.viewDidLoad()
 7     }
 8     override func didReceiveMemoryWarning() {
 9         super.didReceiveMemoryWarning()
10         // Dispose of any resources that can be recreated.
11     }
12  //facebook分享 13  @IBAction func facebooTapped(sender: AnyObject) { 14  var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook) 15  controller.setInitialText("一起来玩女神画廊app吧，就在Github上") 16  controller.addImage(beautyImage.image) 17  self.presentViewController(controller, animated: true, completion: nil) 18  } 19  //twitter分享 20  @IBAction func twitterTapped(sender: AnyObject) { 21  var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTwitter) 22  controller.setInitialText("一起来玩女神画廊app吧，就在Github上") 23  controller.addImage(beautyImage.image) 24  self.presentViewController(controller, animated: true, completion: nil) 25  } 26  //微博分享 27  @IBAction func WeiboTapped(sender: AnyObject) { 28  var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeSinaWeibo) 29  controller.setInitialText("一起来玩女神画廊app吧，就在Github上") 30  controller.addImage(beautyImage.image) 31  self.presentViewController(controller, animated: true, completion: nil) 32  } 33 }
