尝试用这种被称为

 MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; 
     picker.mailComposeDelegate = self; 


     [[picker navigationBar] setTintColor:[UIColor clearColor]];//You can set your colour 
     UIImage *image1 = [UIImage imageNamed: @"bg_header.png"]; 
     UIImageView * iv = [[UIImageView alloc] initWithFrame:CGRectMake(0,0,320,42)]; 
     iv.image = image1; 
     iv.contentMode = UIViewContentModeCenter; 
     [[[picker viewControllers] lastObject] navigationItem].titleView = iv; 
     [[picker navigationBar] sendSubviewToBack:iv]; 
     [iv release]; 
     [self presentViewController:picker animated:NO completion:nil]; 
     [picker release];
