UIViewController類詳解：

通過Nib文件初始化

[objc]?view plaincopy

init(nibName?nibName:?String?,?bundle?nibBundle:?NSBundle?)??

println("nibName?=?\(self.nibName)")????????????????????????????????????//nibName??

println("nibBundle?=?\(self.nibBundle)")????????????????????????????????//nibBundle??

StoryBoard相關

[objc]?view plaincopy

println("storyboard?=?\(self.storyboard)")??????????????????????????????//storyboard<pre?name="code"?class="objc">//在跳轉之前對Segue進行判斷,如果返回false則不之行這個Segue的跳轉,?performSegueWithIdentifier:sender:如果使用了,則這個方法無效??

override?func?shouldPerformSegueWithIdentifier(identifier:?String?,?sender:?AnyObject?)?->?Bool?{??

????return?true??

}??

//跳轉執行??

override?func?prepareForSegue(segue:?UIStoryboardSegue,?sender:?AnyObject?)?{??

???print("prepareForSegue")??

}??

//根據UIStoryBoarSegue的Identifier進行跳轉??

override?func?performSegueWithIdentifier(identifier:?String?,?sender:?AnyObject?)?{??

????super.performSegueWithIdentifier(identifier!,?sender:?sender)??

}??

[objc]?view plaincopy

//subViewController是否能夠執行Unwind?Segue??

override?func?canPerformUnwindSegueAction(action:?Selector,?fromViewController:?UIViewController,?withSender?sender:?AnyObject)?->?Bool?{????

}??

[objc]?view plaincopy

//如果執行Unwind?Segue，就返回Segue??

override?func?segueForUnwindingToViewController(toViewController:?UIViewController,?fromViewController:?UIViewController,?identifier:?String?)?->?UIStoryboardSegue?{??

}??

[objc]?view plaincopy

//能夠執行Segue的Controller??

func?viewControllerForUnwindSegueAction(action:?Selector,?fromViewController:?UIViewController,?withSender?sender:?AnyObject?)?->?UIViewController??{??

}??
