In iOS project, XCode, I have two VCs, VC1 and VC2. What I want to do is in VC1, have a button to go to VC2 using

let VC2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as! VC2
self.presentViewController(loginVC, animated: true)

After VC2 appears, I will never need to go back to VC1 so I want to remove it completely as VC1 has some downloading function that may still run in background. So I want to remove VC1. I have tried the following:

let VC2 = self.storyboard?.instantiateViewControllerWithIdentifier("VC2") as! VC2
self.presentViewController(loginVC, animated: true) {
    self.removeFromParentViewController() 
}

However, that does not seem to do the job as I still see the background download in progress. Is there a simple way of doing it? I do not really want to include navigation controller in this case.

I guess you could set your parentViewController to nil, again I GUESS – Mohsen Shakiba Aug 01 '16 at 05:09
In `viewDidDissapear` of VC1, you should take the task and cancel it and leave the `deinit` of VC1 process for the system, that way is better and less error – Tj3n Aug 01 '16 at 05:24
How could I deinit VC1 ? I am in VC1 currently – user172902 Aug 01 '16 at 06:00
Did you try to remove VC1 from navigation controller stack? – Anoop Nyati Feb 01 '17 at 07:15
