解析和Facebook-PFUser logInWithAuthType無法識別的選擇器錯誤

Question

我在使用Parse向Facebook進行身份驗證時遇到問題。 我的應用程序將正常運行，直到我單擊“登錄Facebook”按鈕，並引發以下錯誤：

閱讀該消息后，該錯誤似乎來自PFFacebookUtils loginWithPermissions方法：

- (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!");
            }
        }
    }];
}

但是，這是Parse記錄的原始登錄信息。 有什么建議么？

更新在進一步分析之后，我注意到此錯誤僅在Parse從1.4.1升級到1.4.2

您必須將Parse 1.4.2與ParseFacebookUtils 1.4.1一起使用。 進行pod update ，它將您的ParseFacebookUtils更新為1.4.2。
