<p>我正在使用下面的代码来创建一个新用户，</p>
<pre><code>[QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
// session created
} errorBlock:^(QBResponse *response) {
// handle errors
NSLog(@"%@", response.error);
}];
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");
}];
</code></pre>
<p>我看到一个答案 <a href="https://stackoverflow.com/a/20593701/756941" rel="noreferrer noopener nofollow">here on SO</a> ，但它会抛出一个错误，即 <code>delegate:self</code> 已被弃用，需要使用上述方法 <code>signUp: successBlock:</code>。</p>
<p>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。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>所有这些请求都是异步的，你不能这样使用它。</p>
<p>正确的方法是等到 session 创建完成后再注册一个用户:</p>
<pre><code>[QBRequest createSessionWithSuccessBlock:^(QBResponse *response, QBASession *session) {
// session created
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);
}];
</code></pre></p>
