我使用下面的代码创建一个新用户，

I'm using the below code to create a new user,

[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");
}];

我看到一个答案这里在SO ，但它抛出一个错误，委托：self 已被弃用，需要使用上述方法 signUp ：successBlock：。

I saw an answer here on SO, but it throws an error, that delegate:self was deprecated and need to use the above method signUp: successBlock:.

有没有人遇到这个问题？如何解决这个问题？任何建议将非常感激。

Did anyone face this issue? How to fix this? Any suggestions would be greatly appreciated.

推荐答案

所有这些请求都是异步的，你不能这样使用。

All these requests are asynchronous and you can't use it this way.

正确的方法是等待直到创建会话，然后注册一个用户：

The right way is to wait until session will be created and then sign up a user:

[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);
}];
