    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

        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)  
    }
