Facebook登录后删除[PFUser currentUser] [英] Delete [PFUser currentUser] after Facebook login

问题描述

我想让我的用户能够删除他们的帐户，从而不会出现在其他用户的供稿中.

I want to give my user the ability to remove their account, thus not showing up in the feeds of other users.

我可以这样做的一种方法是在用户"表中添加活动"列.

One way I could do this is adding an 'active' column to the 'User' table.

更好的方法是从表中删除其User对象.不幸的是，当我执行此操作时，应用程序崩溃，并显示以下错误:除非已通过登录或注册身份验证，否则无法删除用户."

A better way would be to remove their User object from the table. Unfortunately, when I implement code to do so, the app crashes and the following error shows up: 'User cannot be deleted unless they have been authenticated via logIn or signUp'.

也许我的登录代码有问题.

Maybe something is wrong with my login code.

NSArray *permissionsArray = @[@"email", @"public_profile", @"user_friends"];

[PFFacebookUtils logInWithPermissions:permissionsArray block:^(PFUser *user, NSError *error) {
    if (!user) {
        if (error) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Oops, error" message:@"Couldn't login at the moment. Try again later." delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Dismiss", nil];
            [alert show];
        }
    }
    else {
        // Send request to Facebook
        [[FBRequest requestForMe] startWithCompletionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
            // handle response
            if (!error) {
                // Parse the data received
                NSDictionary *userData = (NSDictionary *)result;

                [[PFUser currentUser] setObject:[NSNumber numberWithLongLong:[userData[@"id"] longLongValue]] forKey:@"facebook_id"];
                [[PFUser currentUser] setObject:userData[@"name"] forKey:@"name"];
                [[PFUser currentUser] saveInBackground];


                // Go to home screen here
            }
        }];
    }
}];

删除操作如下:

PFObject *userObject = [PFObject objectWithoutDataWithClassName:@"_User" objectId:[PFUser currentUser].objectId];
[userObject deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
    // back to login view controller
}];

有什么办法解决这个问题吗?

Any idea how to fix this?

推荐答案

为什么已经以[PFUser currentUser]的身份重新获取用户对象?也许您需要直接删除[PFUser currentUser]对象?像这样:

Why are you re-fetching the user object when you already have it as [PFUser currentUser]? Perhaps you need to delete the [PFUser currentUser] object directly? Something like:

[[PFUser currentUser] deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
    // back to login view controller
}];
