[英]Unwind in Xcode 7 Using Swift 2 Does not Work
I have two View Controllers. 我有两个视图控制器。 In the second View Controller, I have a button called "Gidelim".
在第二个View Controller中,我有一个名为“ Gidelim”的按钮。 I want it to turn back to the first View Controller when I click on it.
当我单击它时,我希望它回到第一个View Controller。
For this purpose, I have defined a func in the first View Controller's as below: 为此,我在第一个View Controller中定义了一个func,如下所示:
The func "YeniVCAc" shows the second View Controller and it works. 函数“ YeniVCAc”显示了第二个View Controller,并且可以正常工作。 The func "ilkVCGit" has to return back to this View Controller.
函数“ ilkVCGit”必须返回到该视图控制器。
I have CTRL-dragged the button to the Exit on the second view controller. 我已经在第二个视图控制器上将CTRL的按钮拖动到了Exit。 Then I have chosen ilkVCGit.
然后,我选择了ilkVCGit。
This design must be correct as I think. 我认为这种设计必须正确。 However, the application crashes when I press the button on the second view controller.
但是,当我按下第二个视图控制器上的按钮时,应用程序崩溃。
Connect your button in the Interface Builder to this Action, in the class of your SecondViewController: 在SecondViewController的类中,将Interface Builder中的按钮连接到此Action:
@IBAction func dismiss(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
