[英]Unwind Segue using performSegueWithIdentifier - Doesn't work - Swift 2.1
I am trying to unwind in my button click, after receiving response. 收到回复后,我试图放松按钮的单击。
LoginController LoginController
@IBAction func SignInPressed(sender: AnyObject) {
if (onSuccess) {
performSegueWithIdentifier("unwindToGlobal", sender: AnyObject?())
}
}
and this is where it comes from (GlobalController). 这就是它来自(GlobalController)的地方。
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?)
{
if (segue.identifier == "globalToLogin")
{
NSOperationQueue.mainQueue().addOperationWithBlock({ () -> Void in
let loginController = segue.destinationViewController as? LoginController
})
}
}
This one works and as soon as I enter the app (GlobalController is the starting view), I get directed to Login Page. 这是可行的,一旦我进入应用程序(GlobalController是初始视图),我就被定向到登录页面。 However, when I click on the login button on LoginController, unfortunately it doesn't unwind.
但是,当我单击LoginController上的登录按钮时,不幸的是它不会展开。
When I try to remove these connections and ctrl + drag
button to exit, it just doesn't do anything. 当我尝试删除这些连接并按
ctrl + drag
按钮退出时,它什么也没做。
I couldn't find what I am doing wrong, thus it's not working. 我找不到我在做什么错,因此无法正常工作。 What am I missing?
我想念什么?
