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 } 运行结果: github地址:https://github.com/AbelSu131/BeautyGallery |
