接触swift 刚刚不久，由于从android 开发转到iOS，于是第一件事就是如何进行页面之间进行跳转和传值
跳转方式：
1.storyboard中的segue 跳转方式：
self.performSegueWithIdentifier("next",sender:self);
"next"为 ,segue中在sb中设置的Identifier 的id
传值方式：
// In a storyboard-based application, you will often want to do a little preparation before navigation
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get the new view controller using segue.destinationViewController.
// Pass the selected object to the new view controller.
let dev=segue.destinationViewController as! NextViewController
//segue 在sb 中的传值
dev.nexttext="pass"
}
2.普通的xib 界面的view controller 跳转方式以及传值方式
var nib=XibViewController()//需要跳转的viewcontroller
self.presentViewController(nib, animated:true, completion: nil)
//传值
nib.xibtest.text="连接超时"
3.关闭当前的viewcontroller
self.dismissViewControllerAnimated(true, completion: nil)
4.也可以用protocol 来传值。
