Receiver has no segue with identifier"***"

I encounter this problem for the first time. I checked similar problems on stack overflow, but none of the solutions can solve my issue so I have this posting.

Up to the present, I have two view controllers(let's say A and B) and I am trying to connect them with a segue with name "toB". When I run the program, Xcode told me Receiver(B) has no segue with identifier "toB".

I am pretty sure that the spellings of the identifierin the storyboard and in the code are exactly the same. And the line of the segue has connected the A view controller and B view controller.

But the storyboard IDs of the two view controllers are different. Is it the problem??

Hope someone could help me out. Thanks in advance!

SOLUTION

Thanks for @Amit Shelgaonkar's hint! In my case, moving the performSegueWithIdentifier to viewDidAppear still doesn't work, but moving it to applicationWillEnterForeground solves the problem!

I still don't know why it doesn't work in my case, because when I tried to develop a testing app and put the performSegueWithIdentifier in viewDidAppear, it works perfectly.

Solution

  • you call performSegueWithIdentifier:sender: in the viewDidLoad. You can not dismiss a UIViewController that isn't presented yet. viewDidLoad has purely memory management functions, you can use it as (part of a) constructor. What may work, is to start a segue in viewDidAppear, however I would suggest to start with the view you want at the first time.
