我在带有MFMailComposeViewController的ios 7应用程序中有一个反馈按钮.用户单击此按钮后,mailcomposer将打开,但状态栏将更改为黑色.有谁知道我该怎么办？

我只有ios7才有这个问题.我为ios7定制了我的应用程序.

    MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
            mailController.mailComposeDelegate = self;

            [mailController setSubject:@"Feedback"];
            // Fill out the email body tex
            NSString *emailBody = [NSString stringWithFormat:@"testest"],
                                   [UIDevice currentDevice].model,
                                   [UIDevice currentDevice].systemVersion];
            [mailController setMessageBody:emailBody isHTML:NO];
            [mailController setToRecipients:[NSArray arrayWithObjects:@"support@test.com",nil]];

            dispatch_async(dispatch_get_main_queue(), ^{
                [self presentModalViewController:mailController animated:YES];
}

我正在使用我的应用程序中的共享选项UIActivityViewController; 它在iOS 9.2中工作正常,并且Google+共享选项在iOS 9.3中无效

为了确认这一点,我已经下载了其他具有共享选项的应用程序,UIActivityViewController问题是应用程序的整个UI都挂了.

我该如何解决这个问题？

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

        NSMutableURLRequest* request = [NSMutableURLRequest requestWithURL:URL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];

        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) {

            NSString *responseString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

我有SQLite数据库(DB)并将其作为模型类并在NSMutableArray中获取数据库.我的DB与此DB类似. 学生名称| RegisterNumber | DatesOfJoin(DoJ) 我在tableView中成功显示了DoJ,但我想在tableView中按升序和降序排序DatesOfJoin.任何帮助将不胜感激,并提前感谢您.
