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)
    }
}
