Question

我正在尝试让我的应用程序登录Facebook，但它仍然从解析和Facebook开发人员guild崩溃。这是我的代码。

-(IBAction)LoginWithFacebook {
    // Set permissions required from the facebook user account
    NSArray *permissionsArray = @[@"email", @"password", @"user_about_me", @"user_birthday", @"user_location"];

    [PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
        if (!user) {
            NSLog(@"Uh oh. The user cancelled the Facebook login.");
        } else if (user.isNew) {
            NSLog(@"User signed up and logged in through Facebook!");
        } else {
            NSLog(@"User logged in through Facebook!");
        }
    }];



   }

这是崩溃时收到的错误消息。它很长，我不知道这一切意味着什么，我不确定这是否有用。

也许问题是你使用的图书馆太旧了，我遇到了同样的问题。

这是两个主要步骤：

使用 ParseFacebookUtilsV4.framework 代替 ParseFacebookUtils.framework
将 logInWithPermissions 方法更改为 logInInBackgroundWithReadPermissions

解析facebook崩溃目标c
