我正在使用 UIActivityViewController 在我的应用程序中使用共享选项；它在 iOS 9.2 中工作正常，Google+ 共享选项在 iOS 9.3 中不工作

为了确认这一点，我使用 UIActivityViewController 下载了其他具有共享选项的应用，但问题是该应用的整个 UI 都挂了。

我该如何解决这个问题？

编辑 1: 代码:

        NSURL * URL =  [[NSURL alloc]initWithString:@"http://domainName/message.php?"];

        NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
        [request setHTTPMethod:@"GET"];

        NSString *tempEmailId  = (NSString *)[[NSUserDefaults standardUserDefaults] objectForKey:CURRENT_USER_EMAIL_ID_UD_KEY];
        NSString *tempPassword = (NSString *)[[NSUserDefaults standardUserDefaults] objectForKey:CURRENT_USER_PASSWORD_UD_KEY];

        NSString *basicAuthCredentials = [NSString stringWithFormat:@"%@:%@", tempEmailId, tempPassword];
       [request setValue:[NSString stringWithFormat:@"Basic %@", AFBase64EncodedStringFromString(basicAuthCredentials)] forHTTPHeaderField: @"Authorization"];
       //NSLog(@"request %@\n",request);
       [[[NSURLSession sharedSession] dataTaskWithRequest:request completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
        if (data != nil) {
            NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
            NSArray * activityItems = @[responseString];
            dispatch_async(dispatch_get_main_queue(), ^{
                activityViewController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:activities];
                [activityViewController setValue:@"Today's Recommendations" forKey:@"subject"];
                activityViewController.excludedActivityTypes = @[UIActivityTypePostToFacebook];

[activityViewController setCompletionWithItemsHandler:
                 ^(NSString *activityType, BOOL completed, NSArray *returnedItems, NSError *activityError) {
                     dispatch_async(dispatch_get_main_queue(), ^{
                     NSLog(@"activityType: %@, returnedItems: %@, activityError: %@", activityType, returnedItems, activityError.userInfo);

                     if (completed)
                     {
                         NSLog(@"The Activity: %@ was completed", activityType);
                     }
                    else
                     {
                         NSLog(@"The Activity: %@ was NOT completed", activityType);
                     }
                     });

                 }];

                if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
                    [self presentViewController:activityViewController animated:YES completion:nil];
                }
//if iPad
                else {
                    activityViewController.modalPresentationStyle = UIModalPresentationPopover;

                    // activityViewController.popoverPresentationController.sourceView = sender;

                    activityViewController.popoverPresentationController.sourceView = self.view;

                    if ([sender isKindOfClass:[UIButton class]]) {
                        UIButton *btn = (UIButton *)sender;
                        activityViewController.popoverPresentationController.sourceRect = btn.frame;
                    }

                    [self presentViewController:activityViewController animated:YES completion:nil];
                }
            });
        }
    }] resume];

注意::Mail、Twitter 和 Evernote 正在运行。只有 Google+ 挂断了。

编辑 2::我不太清楚，但我认为 - 它与开放 URL 无关。如果相关，请让我知道如何？
