如何检查 PFUser 是否已验证其电子邮件 - Xcode Parse

Question

我正在尝试检查当前用户之前是否验证过它的电子邮件 他们进行下一步。我在做什么错请帮助谢谢。在后台保存的电话号码有效。当我调用“SavePhoneInBackground”时，应用程序崩溃

（SVProgressHUd 是活动指标）

-(void) SavePhoneInBackground  {

    PFUser *user = [PFUser currentUser];
    user[@"phone"] = _phone_register.text;

    [user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {

        if (!error) {
            NSLog(@"PhoneUpdatingSucces!");
            _phone_register.text = nil;
            [self checkUserEmailVerify];

        }else {

            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Whoops!" message:@"Something went wrong! Try again." delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
            [alert show];
            [SVProgressHUD dismiss];
            NSLog(@"There was an error in the registration!");
        }
    }];
}


-(void) checkUserEmailVerify {

    PFUser *user = [PFUser currentUser];

    if (![[user objectForKey:@"emailVerified"] boolValue]) {
        // Refresh to make sure the user did not recently verify
        [user refresh];

        if (![[user objectForKey:@"emailVerified"] boolValue]) {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Whoops!" message:@"You need to verify your emailadress!" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
            return;
            [SVProgressHUD dismiss];
        }
    }
    // This is a triumph.
    [SVProgressHUD dismiss];
    [self performSegueWithIdentifier:@"login2" sender:self];

}

Answer 1

func giveCaketoUser(user: PFUser) {
                if (user.objectForKey("emailVerified").boolValue == true){
                    println("true")
                } else {
                    println("flase")
                }
            }

这是我在最近的一个项目中使用的东西：

- (BOOL)validateEmail:(NSString *)emailStr {
NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:emailStr];
}

您可以使用正则表达式的其他操作。当我使用这种方法时，我遇到的问题是项目将继续注册用户，同时仍然显示我的自定义警报和 NSLog 错误，但这可能是我的失败而不是方法。

希望这会给您带来正确的方向！

这就是我在我的应用程序中的做法，它只会让经过验证的电子邮件用户访问。您需要根据需要对其稍作修改。

- (void)logInViewController:(MyLogInViewController *)logInController didLogInUser:(PFUser *)user {

if (![[user objectForKey:@"emailVerified"] boolValue]){
    NSLog(@"User not validated email");
    [[[UIAlertView alloc] initWithTitle:@"Access restricted" message:@"To access this area please validate your email address" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil] show];
}
else if ([[user objectForKey:@"emailVerified"] boolValue]){
    NSLog(@"Email validated");
    [self dismissViewControllerAnimated:YES completion:NULL];
    [[[UIAlertView alloc] initWithTitle:@"Welcome back" message:(@"%@", user.username) delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil] show];
}

// [self dismissViewControllerAnimated:YES completion:NULL];

NSLog(@"Login sucessfull and username is %@",user.username);

}

如果您还没有解决，希望这对您有所帮助！
