ios - 在 block 中推送 View

Question

我在完成 block 中调用 View 推送方法但它不起作用，通常当我从另一个非 block 方法调用它时它起作用。我认为它与线程有关，但我无法解决，我该怎么办？

这是我的推送方法:

-(void)goToVenues{
 venuesList *venuesList = [self.storyboard instantiateViewControllerWithIdentifier:@"VenuesList"];
 [self.navigationController pushViewController:venuesList animated:YES];
}

这是完成 block :

    [FSOAuth requestAccessTokenForCode:accessCode
                              clientId:clientID
                     callbackURIString:callbackURI
                          clientSecret:clientSecret
                       completionBlock:^(NSString *authToken, BOOL requestCompleted, FSOAuthErrorCode errorCode) {
            [[NSUserDefaults standardUserDefaults] setObject:authToken forKey:@"token"];
            [self goToVenues];

 }];

Answer 1

将您的方法调用移至主线程，修改后不要忘记同步用户默认设置，如下所示:

dispatch_async(dispatch_get_main_queue(), ^{
    [[NSUserDefaults standardUserDefaults] setObject:authToken forKey:@"token"];
    [[NSUserDefaults standardUserDefaults] syncronize];
    [self goToVenues];
});
