Parse Log in With Twitter Initial Failure - ios

Question

Currently I have a Twitter login that authenticates the user just fine, receiving all the appropriate information for the user necessary for confirming a complete login.
I then am calling the [PFTwitterUtils logInWithBlock:...] method in order to authenticate the user through Parse and populate a new user in _User.
(I am not using just this method to present the Twitter login dialog box as I could not get it to present itself).
Here is the strange part:
On the first time I launch the app, I sign in with Twitter, and then call the logInWithBlock method and receive the following error:
Something went wrong: The operation couldn’t be completed. (NSURLErrorDomain error -1012.)
The strange part is that this issue does not occur at all if I relaunch the app again. The only difference is that upon relaunch I believe the Twitter Account information that I had used before (via browser not accounts) is saved on the device. When I launch the app again, I have it set so that it reloads the previous session: this time the [PFTwitterUtils logInWithBlock:...] works like a charm, creates a new user, etc., without any issue.
NOTE: I have a valid URL saved as the Callback URL on my Twitter App's settings. Also, I hope it is clear that the setup was done correctly given that it works fine on second log in.
Here is the login code I am using:
// Login with Twitter through Parse
[PFTwitterUtils logInWithBlock:^(PFUser *user, NSError *error) {
if (error != nil) {
// Something went wrong
NSLog(#"Something went wrong: %#", [error localizedDescription]);
breakLogin = YES;
[self invalidateSignInTimer];
return;
}
else if (user.isNew){
userObjectID = user.objectId;
[user saveInBackground];
NSLog(#"New User");
}
else if (!user.isNew) {
userObjectID = user.objectId;
[user saveInBackground];
NSLog(#"Returning User. Welcome Back!");
}
}];
I am running out of patience and ideas on why this is happening. If anyone has any ideas please let me know - thanks!
UPDATE:
I noticed that the reason this seems to be happening is such:
The first time i attempt to login there is no PFUser, whereas the second time there seems to be a saved [PFUser currentUser], which allows the [PFTwitterUtils...] method to log in and create the new user.
Yet I am still not sure how to prevent the failure the first time without manually creating a new PFUser and then logging in with Twitter, then PFTwitterUtils...
UPDATE 2
I have resolved this issue with the answer I have provided below. I am leaving this up as I feel this is something that may help others out there in the future.

Answer 1

So after extraneous research, I seemed to have found a solution.
First I made sure that all of my framework files (SKDs, headers, etc) were up to date by removing all of their references from both the project and the library linking.
Second I made sure that all keys and secrets were remade and updated in my
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
Lastly I made double checked that I properly went through the set up for Twitter authentication through Parse's website.
BUT what I found to be the only solution rested in the Callback URL.
When specifying the Callback URL in your Twitter Application under "Settings", I had to uncheck the Lock Callback URL option, despite the recommendation by Twitter. (seen below)
I was a little unhappy that all of this trouble derived from something so mundane, however I was at least pleased that solution was in fact resolved without too much trouble. Hopefully this answer helps someone out there struggling with a similar issue.
