一个、总结

使用Swift去完成iOS的UI接口，事实上，目前的想法和OC实现几乎一致，只是在措辞非常大的差异，修改前更更大的个人控制。为有纯代码强迫症，所以接下来创建一个纯代码动项目，然后在此基础上具体描写叙述经常使用UI控件的Swift代码实现。

二、创建项目

首先创建一个新项目SwiftDemo，语言选择Swift，详情參考《 iOS8开发～Swift（一）入门》，然后打开项目plist文件。删除当中的Main
storyboard file base name一行。其它内容不须要修改。程序会默认从AppDelegate.swift開始运行，但此时主window须要代码初始化。由于我们已经删除了storyboard。所以须要加入例如以下代码：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
// Override point for customization after application launch.
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
self.window!.backgroundColor = UIColor.whiteColor()
self.window!.makeKeyAndVisible() return true
}

如今程序应该能够执行了，只是什么内容都没有。

以下打算搭建一个非经常见都项目框架。主window的rootviewController为一个

UITabBarController对象，UITabBarController对象作为容器，其有两个标签，每一个标签的内容展示为一个

UINavigationController对象。UINavigationController对象的rootViewController为实际的用户界面。相信这个结构使用OC实现大家都非常熟悉了，但使用Swift该怎么样实现呢，事实上思想都是一样都，仅仅只是写法有差别而已，以下具体讨论代码实现了。

三、UI实现具体解释

1、在应用程序启动函数中加入例如以下代码：当中 viewControllerA 和 viewControllerB是需新创建都两个视图控制器，详细实现參考《 iOS8开发～Swift（一）入门》

var window: UIWindow?
var tabBarController: UITabBarController?func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
// Override point for customization after application launch.
self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
self.window!.backgroundColor = UIColor.whiteColor() var viewControllerA = ViewControllerA();
viewControllerA.title = "基本UI" var viewControllerB = ViewControllerB();
viewControllerB.title = "其它" self.tabBarController = UITabBarController()
self.tabBarController!.delegate = self;
self.tabBarController!.viewControllers = [
UINavigationController(rootViewController: viewControllerA),
UINavigationController(rootViewController: viewControllerB)
]
self.tabBarController!.selectedIndex = 0; self.window!.rootViewController = self.tabBarController
self.window!.makeKeyAndVisible() return true
}

这样。之前描写叙述的项目框架就实现了。

假设须要在UITabBarController的代理方法中做一些事情，能够实现其代理：

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UITabBarControllerDelegate

//UITabBarControllerDelegate
func tabBarController(tabBarController: UITabBarController!, didSelectViewController viewController: UIViewController!) { }

执行效果：

2、以ViewControllerA作为UI介绍导航页面，在当中实现一个表视图TableView，其数据源从读取一个plist文件获取：

新建立一个ViewControllerA，取消勾选Xib选项。创建后重写loadView方法，然后初始化一个表视图。主要代码例如以下：

import UIKitclass ViewControllerA: UIViewController, UITableViewDelegate, UITableViewDataSource { var list: NSArray?
var tableView: UITableView? override func loadView() {
super.loadView()
} override func viewDidLoad() {
super.viewDidLoad() self.list = NSArray(contentsOfFile: NSBundle.mainBundle().pathForResource("BasicUI", ofType:"plist"))
println(self.list) self.tableView = UITableView(frame: self.view.frame, style:UITableViewStyle.Plain)
self.tableView!.delegate = self
self.tableView!.dataSource = self
self.tableView!.registerClass(UITableViewCell.self, forCellReuseIdentifier: "Cell")
self.view?.addSubview(self.tableView) } func numberOfSectionsInTableView(tableView: UITableView!) -> Int {
return 1;
} func tableView(tableView: UITableView!, numberOfRowsInSection section: Int) -> Int {
return self.list!.count
} func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell!
{
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as UITableViewCell!
cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator
cell.textLabel.text = self.list?.objectAtIndex(indexPath.row) as String return cell
} // UITableViewDelegate Methods
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!)
{
self.tableView!.deselectRowAtIndexPath(indexPath, animated: true) var itemString = self.list?.objectAtIndex(indexPath.row) as String var viewController : UIViewController?
if itemString == "UIView" {
viewController = TheViewController()
} //省略部分代码
else {
println("viewController is nil")
} viewController!.hidesBottomBarWhenPushed = true
self.navigationController.pushViewController(viewController, animated:true)
} override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning() // Dispose of any resources that can be recreated.
}
}

3、以下逐个介绍各个控件的实现

（1）UIView

import UIKitclass TheView: UIView {
override func drawRect(rect: CGRect) {
UIColor.redColor().setFill();
UIRectFill(CGRectMake(0, 100, 100, 100));
}
}class TheViewController: UIViewController { override func loadView() {
let theView = TheView()
theView.backgroundColor = UIColor.brownColor()
theView.layer.cornerRadius = 3
theView.layer.borderWidth = 5
theView.layer.borderColor = UIColor.darkGrayColor().CGColor self.view = theView;
} override func viewDidLoad() {
super.viewDidLoad()// 加入手势
let recognizer = UITapGestureRecognizer(target: self, action: "tapAction:")
recognizer.numberOfTapsRequired = 2;
recognizer.numberOfTouchesRequired = 1;
self.view.addGestureRecognizer(recognizer)
} func tapAction(sender: UIGestureRecognizer)
{
println("tapAction")
} override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

当中涉及到视图手势加入，视图重会，改动Layer等实现，效果如图：

（2）UILabel

import UIKitclass LabelViewController: UIViewController { override func loadView() {
super.loadView();
} override func viewDidLoad() {
super.viewDidLoad() var label = UILabel(frame: CGRectMake(0, 100, self.view.bounds.size.width, 200))
label.backgroundColor = UIColor.blackColor()
label.textColor = UIColor.whiteColor()
label.numberOfLines = 0
label.lineBreakMode = NSLineBreakMode.ByWordWrapping
label.text = "Swift is designed to provide seamless compatibility with Cocoa and Objective-C. You can use Objective-C APIs (ranging from system frameworks to your own custom code) in Swift, and you can use Swift APIs in Objective-C. "
label.font = UIFont.italicSystemFontOfSize(20) self.view.addSubview(label)
} override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

效果如图：

（3）UIButton

import UIKitclass ButtonViewController: UIViewController { override func loadView() {
super.loadView();
} override func viewDidLoad() {

button.frame = CGRect(x:100, y:200, width:100, height:100);
button.setTitleColor(UIColor.redColor(), forState: UIControlState.Normal)
button.setTitleColor(UIColor.greenColor(), forState:UIControlState.Selected)
button.setTitle("Normal", forState:UIControlState.Normal)
button.setTitle("Selected", forState:UIControlState.Selected)
button.setBackgroundImage(UIImage(named: "image.png"), forState:UIControlState.Normal)
button.tag = 1000;
button.clipsToBounds = true;
button.layer.cornerRadius = 5;
button.addTarget(self, action:"buttonAction:", forControlEvents:UIControlEvents.TouchUpInside) self.view.addSubview(button)
} func buttonAction(sender: UIButton) {
println("buttonAction")
} override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}

imageView.backgroundColor = UIColor.whiteColor();
imageView.animationImages = [
UIImage(contentsOfFile: NSBundle.mainBundle().pathForResource("bird-01", ofType:"png")),
UIImage(contentsOfFile: NSBundle.mainBundle().pathForResource("bird-02", ofType:"png")),
UIImage(contentsOfFile: NSBundle.mainBundle().pathForResource("bird-03", ofType:"png")),
UIImage(named: "bird-04.png")
]
imageView.contentMode = UIViewContentMode.ScaleAspectFit
imageView.animationDuration = 1;

} override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
