Change main title color of navigation in MFMailComposeViewController
提问by user1451163
I haven't problem for change color of main title of navigation on a normal viewController but on a MFMailComposeViewController, it isn't possible. I can change colors of buttons (cancel and send), I can set background of navigation bar but not possible to change color of title. I don't want set a new title (apparently, it's not allow by Apple), I just want change the color :'(
我在普通 viewController 上更改导航主标题的颜色没有问题，但在 MFMailComposeViewController 上，这是不可能的。我可以更改按钮的颜色（取消和发送），我可以设置导航栏的背景但无法更改标题的颜色。我不想设置新标题（显然，Apple 不允许），我只想更改颜色:'(
Please help me. Thanks

NSDictionary *navbarTitleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:
[UIColor whiteColor],UITextAttributeTextColor,
[UIColor blackColor], UITextAttributeTextShadowColor,
[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];
Or
或者
navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor yellowColor] forKey:UITextAttributeTextColor];
Hope its work for you..

This is the correct answer for iOS 7, 8, 9, and 10:
这是 iOS 7、8、9 和 10 的正确答案：
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[[picker navigationBar] setTitleTextAttributes:[NSDictionary dictionaryWithObject:[UIColor blackColor] forKey:NSForegroundColorAttributeName]];
Here is why:
原因如下：
The check marked answer above (by Mani) referencing [UINavigationBar appearance]is incorrect as it will change the color of the title in the UINavigationBarthat is popping the MFMailComposeViewControlleras well, which was an effect I didn't want. You need to specifically get the picker's NavBar as my code does.
上面（由 Mani）引用的检查标记答案[UINavigationBar appearance]是不正确的，因为它会改变UINavigationBar弹出的标题的颜色MFMailComposeViewController，这是我不想要的效果。您需要像我的代码一样专门获取选择器的 NavBar。
Setting tintColoris also incorrect as of iOS 7 (the other answer by Mani) as it sets the colors of the buttons, not the title.
tintColor从 iOS 7 开始，设置也不正确（Mani 的另一个答案），因为它设置按钮的颜色，而不是标题。
Also, UITextAttributeTextColoris now deprecated, please use NSForegroundColorAttributeName.
此外，UITextAttributeTextColor现在已弃用，请使用NSForegroundColorAttributeName.

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc]init];
picker.mailComposeDelegate = self;
[[picker navigationBar] setTintColor:[UIColor blackColor]];

For colors other than black, play around with this code:
对于黑色以外的颜色，请使用以下代码：
MFMailComposeViewController *mailController = [MFMailComposeViewController new];
[mailController.navigationBar setTintColor:[UIColor colorWithHue:240.0f/359.0f
saturation:85.0f/100.0f
brightness:60.0f/100.0f
alpha:0.0f]];
