MFMailComposer 外观不正确

Question

我正在努力将 sMFMailComposer 用于在我的应用程序中发送短信。下面是我创建和显示消息共享组件的代码：

- (void)shareWithMessages {
    
    if(![MFMessageComposeViewController canSendText]) {
        UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"Error" message:@"Your device doesn't support SMS!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
        [warningAlert show];
        return;
    }
    
    NSString *message = self.articleTitle;
    message = [message stringByAppendingString:@" "];
    message = [message stringByAppendingString:self.urlString];
    
    MFMessageComposeViewController *messageController = [[MFMessageComposeViewController alloc] init];
    messageController.messageComposeDelegate = self;
    [messageController setBody:message];
        
    // Present message view controller on screen
    [self presentViewController:messageController animated:YES completion:nil];
}

显示分享编辑器时，“新消息”文本显示为白色：

我试过像这样设置色调：

[[messageController navigationBar] setTintColor:[UIColor blackColor ]];

...但这没有效果。有谁知道为什么文本设置为白色，因此无法阅读？

Answer 1

可能在您的代码中某处您正在更改 [UINavigationBar 外观]。所以在调用

之前尝试设置 UINavigationBar 的外观

shareWithMessage

也许以下 3 个之一可以解决问题：

[[UINavigationBar appearance] setTintColor:[UIColor yourColor]];
[[UINavigationBar appearance] setBarTintColor:[UIColor yourColor]];
[[UINavigationBar appearance] setTitleTextAttributes:
     @{NSForegroundColorAttributeName:[UIColor yourColor]}];
