ios - [SLComposeViewController initWithExtension :requestedServiceType:]_block_invoke + 84 崩溃

Question

我在 SLComposeViewController 上遇到一些崩溃

Crashed: com.apple.extension.global-state-queue

在我看来，引用不知何故丢失了？有什么想法吗？

我没有做任何特别的事情

- (void)presentTwitterShareWithURL:(NSURL *)url {

    if (url == nil) {
        return;
    }

    SLComposeViewController * cvc = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [cvc addURL:url];

    [cvc setCompletionHandler:^(SLComposeViewControllerResult result) {

        if (SLComposeViewControllerResultDone == result) {

            [[Analytics shared] trackWithCategory:@"Web" action:@"Tap" label:@"Share - Twitter"];

        }

    }];

    [self.navigationController presentViewController:cvc animated:YES completion:nil];

}

注意:在我看来它与 iOS11 相关，因为我不记得以前有过这个问题，而且除了 iOS11 之外没有跟踪它

Answer 1

SLServiceTypeTwitter 在 iOS 11 中被移除，你需要使用 Twitter 自己的分享方案来实现这个功能。
