Question

同时 signing up a new user在带有登录名和密码凭据的 ios 应用程序的 QuickBlox 中，应用程序崩溃并且 NSLog 控制台显示如下错误，

Terminating app due to uncaught exception 'BaseServiceException', reason: 'You have missed the authorization call. Please insert following code inside your application [QBRequest createSessionWithSuccessBlock:errorBlock:]; Before any other code, that uses our service, but after setup credentials.

我正在使用下面的代码创建一个新用户，

[QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
    // session created
} errorBlock:^(QBResponse *response) {
    // handle errors
    NSLog(@"%@", response.error);
}];

QBUUser *user = [QBUUser user];
user.password = @"azhhdsf";
user.login = @"dsfgsgf";

// Registration/sign up of User
[QBRequest signUp:user successBlock:^(QBResponse *response, QBUUser *user) {
    // Sign up was successful
} errorBlock:^(QBResponse *response) {
    // Handle error here
    NSLog(@"error while signing up with QB");
}];

我看到了一个答案here on SO ，但它会抛出一个错误，即 delegate:self 已被弃用，需要使用上述方法 signUp: successBlock:。

有人遇到过这个问题吗？如何解决这个问题？任何建议将不胜感激。

所有这些请求都是异步的，你不能这样使用它。

正确的方法是等到 session 创建后再注册用户:

[QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
    // session created

    QBUUser *user = [QBUUser user];
    user.password = @"azhhdsf";
    user.login = @"dsfgsgf";

    // Registration/sign up of User
    [QBRequest signUp:user successBlock:^(QBResponse *response, QBUUser *user) {
        // Sign up was successful
    } errorBlock:^(QBResponse *response) {
        // Handle error here
        NSLog(@"error while signing up with QB");
    }];
} errorBlock:^(QBResponse *response) {
    // handle errors
    NSLog(@"%@", response.error);
}];
