自定义NavigationBar在swift中(Custom NavigationBar in swift)

自定义NavigationBar在swift中(Custom NavigationBar in swift)

我对swift和ios非常陌生，所以我需要对以下概念进行清理

我创建了一个视图，其中一个按钮具有后退箭头的背景图像，按钮操作我将返回到之前的控制器，即登录，这样做是否安全，而不是使用NavigationController？

@IBAction func onBackPressed(sender: AnyObject) { let aaa : Login = self.storyboard?.instantiateViewControllerWithIdentifier("Login") as! Login self.presentViewController(aaa, animated: true, completion: nil) }

谢谢

I am very much new to swift and ios so i need my doubts to be cleared for the below concept

I have created a view with a button having background image of back arrow and on button action i am going back to the previous controller which is the Login, is it safe to do it this way instead of using NavigationController??

@IBAction func onBackPressed(sender: AnyObject) { let aaa : Login = self.storyboard?.instantiateViewControllerWithIdentifier("Login") as! Login self.presentViewController(aaa, animated: true, completion: nil) }

Thanks

当您想要推送到下一个View Controller时，导航控制器是最佳选择。

（即）导航控制器 - >视图控制器 - >视图控制器[推送]。

所以我的建议是，如果你想回到以前的视图控制器使用导航控制器

当您想要提供新的View Controller时 ，不需要时间。

Navigation controller is best when you want to push to next View Controller.

(i.e) Navigation Controller ->View Controller ->View Controller[for Push].

So my suggestion is if you want to come back to previous view controller use Navigation Controller

When you want to present a new View Controller that time no need.
