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：

 import UIKit
 class ViewController: UIViewController {

     @IBOutlet weak var beautyPicker: UIPickerView!
     let beauties = ["范冰冰","李冰冰","王菲","杨幂","周迅"]
     override func viewDidLoad() {
         super.viewDidLoad()
         beautyPicker.dataSource = self
         beautyPicker.delegate = self
     }
     override func didReceiveMemoryWarning() {
         super.didReceiveMemoryWarning()
         // Dispose of any resources that can be recreated.
     }

     override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
         if segue.identifier == "GoToGallery"{
             let index = beautyPicker.selectedRowInComponent(0)
             var imageName:String?
             switch index{
             case 0:
                 imageName = "fanbingbing"
             case 1:
                 imageName = "libingbing"
             case 2:
                 imageName = "wangfei"
             case 3:
                 imageName = "yangmi"
             case 4:
                 imageName = "zhouxun"
             default:
                 imageName = nil

             }
             var vc = segue.destinationViewController as! GalleryController
             vc.imageName = imageName
         }
     }
 }

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

 import UIKit

 extension ViewController:UIPickerViewDataSource{
     // returns the number of 'columns' to display.
     func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int{
         return 1
     }
     // returns the # of rows in each component..
     func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
         return beauties.count
     }
 }
 extension ViewController:UIPickerViewDelegate{
     func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String!{
         return beauties[row]
     }
 }

GalleryController.swift文件代码：

 import UIKit
 import Social

 class GalleryController: UIViewController {
     var imageName:String?

     @IBOutlet weak var beautyImage: UIImageView!
     override func viewDidLoad() {
         super.viewDidLoad()
         /*if (imageName != nil){
             beautyImage.image = UIImage(named: imageName!)//修改前
         }*/

         if let name = imageName {
             beautyImage.image = UIImage(named: name)
             switch name{
             case "fanbingbing":
                 navigationItem.title = "范冰冰"
             case "libingbing":
                 navigationItem.title = "李冰冰"
             case "wangfei":
                 navigationItem.title = "王菲"
             case "yangmi":
                 navigationItem.title = "杨幂"
             case "zhouxun":
                 navigationItem.title = "周迅"
             default:
                 navigationItem.title = "女神画廊"
             }
         }
     }
     override func didReceiveMemoryWarning() {
         super.didReceiveMemoryWarning()
         // Dispose of any resources that can be recreated.
     }

     //分享按钮
     @IBAction func shareTapped(sender: AnyObject) {
         var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTencentWeibo)
         controller.setInitialText("一起来玩女神画廊app吧，就在Github上")
         controller.addImage(beautyImage.image)
         self.presentViewController(controller, animated: true, completion: nil)
     }
 }

KoreanViewController文件代码：

 import UIKit
 import Social
 class KoreanViewController: UIViewController {
     @IBOutlet weak var beautyImage: UIImageView!
     override func viewDidLoad() {
         super.viewDidLoad()
     }
     override func didReceiveMemoryWarning() {
         super.didReceiveMemoryWarning()
         // Dispose of any resources that can be recreated.
     }
     //facebook分享
     @IBAction func facebooTapped(sender: AnyObject) {
         var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
         controller.setInitialText("一起来玩女神画廊app吧，就在Github上")
         controller.addImage(beautyImage.image)
         self.presentViewController(controller, animated: true, completion: nil)
     }
     //twitter分享
     @IBAction func twitterTapped(sender: AnyObject) {
         var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeTwitter)
         controller.setInitialText("一起来玩女神画廊app吧，就在Github上")
         controller.addImage(beautyImage.image)
         self.presentViewController(controller, animated: true, completion: nil)
     }
     //微博分享
     @IBAction func WeiboTapped(sender: AnyObject) {
         var controller: SLComposeViewController = SLComposeViewController(forServiceType: SLServiceTypeSinaWeibo)
         controller.setInitialText("一起来玩女神画廊app吧，就在Github上")
         controller.addImage(beautyImage.image)
         self.presentViewController(controller, animated: true, completion: nil)
     }
 }

运行结果：
