如何更改MFMailComposeViewController的导航栏？

Question

i want to change the navigation bar of MFMailComposeViewController to black color.

how can i change.

Answer 1

Note that MFMailComposeViewController inherits from UINavigationController so it also has navigationBar property.

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.navigationBar.barStyle = UIBarStyleBlack;

Answer 2

I know this post is quite dated but for someone who might find it useful, try:

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]];
