+[PFDateFormatter sharedFormatter]: unrecognized selector sent to class 0x1001f31d0 - ios

Question

When linking my iOS with Facebook through Parse with the following code I get the following error:
+[PFDateFormatter sharedFormatter]: unrecognized selector sent to class 0x1001f31d0
Unsure of how to handle this, and this error executes when the following block is called:
[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
[_activityIndicator stopAnimating]; // Hide loading indicator
if (!user) {
NSString *errorMessage = nil;
if (!error) {
NSLog(#"Uh oh. The user cancelled the Facebook login.");
errorMessage = #"Uh oh. The user cancelled the Facebook login.";
} else {
NSLog(#"Uh oh. An error occurred: %#", error);
errorMessage = [error localizedDescription];
}
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Log In Error"
message:errorMessage
delegate:nil
cancelButtonTitle:nil
otherButtonTitles:#"Dismiss", nil];
[alert show];
} else {
if (user.isNew) {
NSLog(#"User with facebook signed up and logged in!");
} else {
NSLog(#"User with facebook logged in!");
}
[self.navigationController popToRootViewControllerAnimated:YES];
}
}];

Answer 1

I fixed this by removing all the Parse and Facebook frameworks from my project, and then adding this to my podfile:
pod 'Facebook-iOS-SDK'
pod 'Parse'
pod 'ParseFacebookUtils'
and reinstalling my podfile. For whatever reason, something is missing from the Parse or Facebook frameworks downloaded from the website. The podfiles fixed the issue for me.
