Storyboard

    override func shouldPerformSegueWithIdentifier(identifier: String, sender: AnyObject?) -> Bool {
        if identifier == "f2s" {
            return true
        }
        
        return false
    }
    
    //Storyboard准备跳转
    //第二个参数表示触发跳转事件发生的控件
    override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
        let cell = sender as! UITableViewCell
        //根据Cell获取位置
        let indexPath = tableView.indexPathForCell(cell)
        
        let second = segue.destinationViewController as! SecondViewController;
        second.c = "\(indexPath!.row)"
    }

ViewController

class ViewController: UIViewController {

    //1.通过代码创建对象时调用
    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: NSBundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
        
        print("ViewController::init(nibName:bundle:)")
    }
    
    //通过Storyboard创建对象时自动调用
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        
        print("ViewController::init(coder:)")
    }
    
    //[2.]Storyboard中创建的,如果代码创建不被调用
    override func awakeFromNib() {
        super.awakeFromNib()
        
        print("ViewController:awakeFromNib()")
    }
    
    //3.加载self.view
    //唯一一个可以更换self.view的位置
    //比需要在里面创建self.view
    override func loadView() {
        print("ViewController:loadView()")
        
        let v = UIView()
        v.backgroundColor = UIColor.greenColor()
        self.view = v
    }
    
    //4.self.view已经被创建
    override func viewDidLoad() {
        super.viewDidLoad()
        
        print("ViewController::viewDidLoad()")
    }

    //5. 页面将要显示
    override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)
        
        print("ViewController::viewWillAppear(:)")
    }
    
    //6. 将要开始布局
    override func viewWillLayoutSubviews() {
        super.viewWillLayoutSubviews()
        
        print("ViewController::viewWillLayoutSubviews()")
    }
    
    //7. 布局完成
    override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()
        
        //可以获取自动布局控件的真实位置和大小
        print("ViewController::viewDidLayoutSubviews()")
    }
    
    //8. 页面已经显示
    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)
        
        print("ViewController::viewDidAppear(:)")
    }
    
    //页面将要消失
    override func viewWillDisappear(animated: Bool) {
        super.viewWillDisappear(animated)
        
        print("ViewController::viewWillDisappear(:)")
    }
    
    override func viewDidDisappear(animated: Bool) {
        super.viewDidDisappear(animated)
        
        print("ViewController:viewDidDisappear(:)")
    }
    
    deinit {
        print("deinit")
    }
}
