解析和Facebook-PFUser logInWithAuthType无法识别的选择器错误

Question

I am having an issue using Parse to authenticate with Facebook. My app will run fine until I hit the login to facebook button, and the below error is thrown:

libc++abi.dylib: terminating with uncaught exception of type NSException

After reading the message, it looks like the error is coming from the PFFacebookUtils loginWithPermissions method:

- (IBAction)loginButtonTouchHandler:(id)sender {
    // Set permissions required from the facebook user account
    NSArray *permissionsArray = @[ @"user_about_me", @"user_relationships", @"user_birthday", @"user_location"];

    // Login PFUser using Facebook
    [PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {

        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!");
            }
        }
    }];
}

However, this is a vanilla login as documented by Parse. Any suggestions?

Update After analyzing this further, I am noticing that this error only occurs when Parse is upgraded from 1.4.1 to 1.4.2

Answer 1

You must be using Parse 1.4.2 with ParseFacebookUtils 1.4.1. Do a pod update and it will update your ParseFacebookUtils to 1.4.2.
