我在我的应用程序中使用 mfmessagecomposeviewcontroller 发送短信。我的问题是，当视图出现时，导航标题和按钮的标题字体与应用程序字体不同。我想改变这个标题的字体。我有很多尝试设置它，但我做不到。请给我一些例子或想法，我该怎么做。

我的代码如下

 if([MFMessageComposeViewController canSendText])
        {
            MFMessageComposeViewController *messageController=[[MFMessageComposeViewController alloc] init];
            messageController.messageComposeDelegate=self;
            messageController.topViewController.navigationController.navigationBar.titleTextAttributes=[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Tijjxdydjmmdouybfrertnsaenp" size:21],UITextAttributeFont, nil];
            [messageController.topViewController.navigationItem.rightBarButtonItem setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Tijjxdydjmmdouybfrertnsaenp" size:21],UITextAttributeFont, nil] forState:UIControlStateNormal];
            messageController.body=@"Hey, you should get this app, it allows us to create and share recipes with each other, & it also has a 7 day meal plan with grocery list. https://itunes.apple.com/us/app/fit-chick-meal-plan-recipe/id576329137?ls=1&mt=8 ";
            messageController.title=@"SMS";
            [messageController setModalTransitionStyle:UIModalPresentationPageSheet];
            [self presentViewController:messageController animated:YES completion:^(void){}];
        }

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    switch (result) {
        case MessageComposeResultSent: 
        {
            [AppUtility displayAlertForTitle:@"Message Status" forMessage:@"Message has been sent successfully" forDelegate:nil forCancelButton:@"Ok"];
        }
            break;
        case MessageComposeResultCancelled:
        {
            NSLog(@"Message sending cancelled");
        }
            break;
        case MessageComposeResultFailed:
        {
            [AppUtility displayAlertForTitle:@"Message Status" forMessage:@"Message sending failed" forDelegate:nil forCancelButton:@"Ok"];
        }
            break;
        default:
        {
            [AppUtility displayAlertForTitle:@"Message Status" forMessage:@"Message sending failed" forDelegate:nil forCancelButton:@"Ok"];
        }
            break;
    }
    [self dismissViewControllerAnimated:YES completion:nil];

}

提前致谢。

用这个：

messageController.topViewController.navigationItem.titleView = yourLabelHereWithANyFont;

在其中创建UILabel并更改字体并提供给titleView.
