Question

我试图检查当前用户之前是否已经验证了它的电子邮件他们继续下一步。我做错了什么，请帮助谢谢。在后台保存的电话号码工作..当我呼叫＆＃34; SavePhoneInBackground＆＃34;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];

}

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

以下是我最近的一个项目中使用的内容：

- (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。

希望这会让你朝着正确的方向前进！

这是我在我的应用程序中执行此操作的方式，它只会让经过验证的电子邮件用户访问。您需要根据需要稍微修改它。

- (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);

}

希望如果你还没有解决它，这会有所帮助！
