Swift

UIViewController类详解：

通过Nib文件初始化

init(nibName nibName: String?, bundle nibBundle: NSBundle?)
println("nibName = (self.nibName)")                                    //nibName
println("nibBundle = (self.nibBundle)")                                //nibBundle

StoryBoard相关

println("storyboard = (self.storyboard)")                              //storyboard<pre name="code" class="objc">//在跳转之前对Segue进行判断,如果返回false则不之行这个Segue的跳转, performSegueWithIdentifier:sender:如果使用了,则这个方法无效
override func shouldPerformSegueWithIdentifier(identifier: String?, sender: AnyObject?) -> Bool {
    return true
}
//跳转执行
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
   print("prepareForSegue")
}
//根据UIStoryBoarSegue的Identifier进行跳转
override func performSegueWithIdentifier(identifier: String?, sender: AnyObject?) {
    super.performSegueWithIdentifier(identifier!, sender: sender)
}

//subViewController是否能够执行Unwind Segue
override func canPerformUnwindSegueAction(action: Selector, fromViewController: UIViewController, withSender sender: AnyObject) -> Bool {
}

//如果执行Unwind Segue，就返回Segue
override func segueForUnwindingToViewController(toViewController: UIViewController, fromViewController: UIViewController, identifier: String?) -> UIStoryboardSegue {
}

//能够执行Segue的Controller
func viewControllerForUnwindSegueAction(action: Selector, fromViewController: UIViewController, withSender sender: AnyObject?) -> UIViewController? {
}

Unwindsegue的实现原理请参考相关文章

View相关

println("view = (view)")
println("view is loaded = (isViewLoaded())")
title = "ViewController"<pre name="code" class="objc">//如果不是nib文件初始化而来，初始化的时候需要调用这个方法初始化view,此方法不能主动调用,是系统调用的<pre name="code" class="objc">override func loadView() {
    super.loadView()<pre name="code" class="objc">}//view初始化以后调用

override func viewDidLoad() {

    super.viewDidLoad()   <span style="font-family: Arial, Helvetica, sans-serif;">//view将可见的时候调用</span>
} <pre name="code" class="objc">override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)
}

// view变得完全可见了以后执行
override func viewDidAppear(animated: Bool) {
    super.viewDidAppear(animated)
}

//view被遮挡或者隐藏时调用
override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(animated)
}

//view被遮挡或者隐藏后调用
override func viewDidDisappear(animated: Bool) {
    super.viewDidDisappear(animated)
}

模式跳转

//设置模式跳转的类别,但是必须是目的Controller设置,不能是上级设置
//CoverVertical, FlipHorizontal, CrossDissolve, PartialCurl四种类型
viewController.modalTransitionStyle = .FlipHorizontal
//设置模式展示样式,适合于iPad上
viewController.modalPresentationStyle = .FullScreen
//如果展示不是.FullScreen, 那么设置是不是捕获statusBar的样式,适合iPad
viewController.modalPresentationCapturesStatusBarAppearance = true
//判断在模式跳转时消失是否键盘
viewController.disablesAutomaticKeyboardDismissal()

presentViewController(viewController, animated: true) { () -> Void in
    //跳转到下个界面
}
dismissViewControllerAnimated(true , completion: { () -> Void in
    //回复模式跳转

})

配置View的layout

// layoutSubviews方法调用之前
override func viewWillLayoutSubviews() {
    super.viewWillLayoutSubviews()
}
// layoutSubviews方法调用之后
 override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
}<pre name="code" class="objc">

updateViewConstraints()

//延伸的方向--set which sides of your view can be extended to cover the whole screen.
if self.respondsToSelector(Selector("edgesForExtendedLayout")) {
    self.edgesForExtendedLayout = .None
}
//Scrollview滚动时处于全屏,默认YES
if self.respondsToSelector(Selector("automaticallyAdjustsScrollViewInsets")) {
     self.automaticallyAdjustsScrollViewInsets = true
}
//当statusbar是透明时，是否扩展至StatusBar，默认情况下是NO，且statusbar不是透明的
if self.respondsToSelector(Selector("extendedLayoutIncludesOpaqueBars")) {
    self.extendedLayoutIncludesOpaqueBars = false
}

//控制view的大小UIPopoverController用的比较的广泛
self.preferredContentSize = self.view.bounds.size

跳转相关

isBeingPresented()                                                      //是否在展示
isBeingDismissed()                                                      //是否在dismiss

isMovingToParentViewController()
isMovingFromParentViewController()

旋转相关

//是否需要旋转
override func shouldAutorotate() -> Bool {
    return true
}
//支持的方向
override func supportedInterfaceOrientations() -> Int {
    return 2
}
//优先支持的方向
override func preferredInterfaceOrientationForPresentation() -> UIInterfaceOrientation {
    return .Portrait
}

自定义的ViewController Container

//https://developer.apple.com/library/ios/featuredarticles/ViewControllerPGforiPhoneOS/CreatingCustomContainerViewControllers/CreatingCustomContainerViewControllers.html
//addChildVIewController:调用这个方法指明一个视图控制器作为你的子视图。
func addChildViewController(childController: UIViewController) {

}
//调用这个方法将一个视图控制器从你的子视图列表里移除。
func removeFromParentViewController() {

}
//这是一个使用一个唯一可选的视图替换另一个视图的新方法,或者移动一个子视图到前台来。通过使用这个方法,这个视图控制器的生命周期信息会被正确地发送出去        func transitionFromViewController(fromViewController: UIViewController, toViewController: UIViewController, duration: NSTimeInterval, options: UIViewAnimationOptions, animations: () -> Void, completion: ((Bool) -> Void)?) {

}
//将要移到父Controller
func willMoveToParentViewController(parent: UIViewController?) {

}
//已经移到父Controller
func didMoveToParentViewController(parent: UIViewController?) {

}
//触发子ViewController的viewWillAppear
func beginAppearanceTransition(isAppearing: Bool, animated: Bool) {

}
//触发childd的viewDidAppear这些方法
func endAppearanceTransition() {

}
//child ViewController的作为状态栏
func childViewControllerForStatusBarStyle() -> UIViewController? {
    return nil;
}
//child ViewController的状态栏是否隐藏设置状态栏
func childViewControllerForStatusBarHidden() -> UIViewController? {
    return nil;
}

恢复相关

restorationIdentifier 恢复标示
restorationClass      恢复的类
override func encodeRestorableStateWithCoder(coder: NSCoder) {

}
override func decodeRestorableStateWithCoder(coder: NSCoder) {

}
applicationFinishedRestoringState() 恢复完成

获得其他的ViewController

println("parentViewController=(self.parentViewController)")            //父类Controller
println("presentedViewController=(self.presentedViewController)")      //Controller模式跳转到去Controller或父容器
println("presentingViewController=(self.presentingViewController)")    //Controller模式跳转来自于Controller或父容器
//        self.navigationController
//        self.tabBarController
//        self.presentationController
//        self.splitViewController
//        self.popoverPresentationController

StatusBar相关

//如果展示不是.FullScreen, 那么设置是不是捕获statusBar的样式,适合iPad
viewController.modalPresentationCapturesStatusBarAppearance = true
//child ViewController的作为状态栏
func childViewControllerForStatusBarStyle() -> UIViewController? {
    return nil;
}
//child ViewController的状态栏是否隐藏设置状态栏
func childViewControllerForStatusBarHidden() -> UIViewController? {
    return nil;
}
//设置当前ViewController的StatusBar的样式
override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .Default
}
//隐藏还是展示statusBar
override func prefersStatusBarHidden() -> Bool {
    return true
}
//statusBar的改变动画
override func preferredStatusBarUpdateAnimation() -> UIStatusBarAnimation {
    return .Fade
}
//当statusBar的状态改变后需要调用刷新
//    setNeedsStatusBarAppearanceUpdate()
