如何自定义 MFMailComposeViewController 的导航栏颜色？
从这段代码将以原始颜色显示我如何将其更改为另一种颜色？ 也许需要覆盖它？
MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
mail.mailComposeDelegate = self;
if ([MFMailComposeViewController canSendMail]) {
[mail setToRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]];
[mail setSubject:@"support"];
[mail setMessageBody:@"enter your message here" isHTML:NO];
[self presentModalViewController:mail animated:YES];
}
from this code will show in original color how can i change it to another color?
maybe it need to be override?
MFMailComposeViewController *mail = [[MFMailComposeViewController alloc] init];
mail.mailComposeDelegate = self;
if ([MFMailComposeViewController canSendMail]) {
[mail setToRecipients:[NSArray arrayWithObjects:@"[email protected]",nil]];
[mail setSubject:@"support"];
[mail setMessageBody:@"enter your message here" isHTML:NO];
[self presentModalViewController:mail animated:YES];
}

我还没有这样做，所以请谨慎对待这个答案。
MFMailComposeViewController继承自UINavigationController。这意味着它将有一个navigationBar属性。获得导航栏后，您可以修改其tintColor属性。I haven't done this so take this answer with appropriate caution.
MFMailComposeViewControllerinherits fromUINavigationController. That means it'll have anavigationBarproperty. Once you have the navigationBar you can modify itstintColorproperty.实际上，iPhone SDK 禁止您修改 MFMailComposeViewController 的外观。从文档（此处):
抱歉...
Actually, the iPhone SDK prohibits you from modifying the appearance MFMailComposeViewController. From the docs (here):
Sorry...
自 Apple Docs 中的更高版本 iOS 起你应该使用 UIAppearance 协议
As of later versions of iOS in Apple Docs you should use UIAppearance protocol
