Question

I have customize my UINavigationBar with UINavigationBar drawRect and it is working fine until I fire up MFMailComposeViewController, which gives me a trouble as I couldn’t override UIBarButton for the mail class, it create akward view like below:

While I try to prevent the MFMailComposeViewController and produce code below for using the default drawRect for MFMailComposeViewController, it even worse it create a black UIBar:

The Code:

@implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect {


    //Prevent Mail Controller For Customizing NavigationBar
    for (UIView* next = [self superview]; next; next = next.superview) {
        UIResponder* nextResponder = [next nextResponder];
        if ([nextResponder isKindOfClass:[MFMailComposeViewController class]]) {
            [super drawRect:rect];
            return;
        }
    }

    UIImage *image = [UIImage imageNamed: @"titleBar.png"];
    [image drawInRect:CGRectMake(0, 0, 320, 44)];   

}
@end

What I am trying to do here is to make sure MFMailComposeViewController having the same style of UINavigationBar and UIButtonItem. It can be either way:

1) Both UINavigationBar and UIButtonItem have customized background

2) Default UINavigationBar style (gradient blue)

Would like to know can I achieve this? Thanks in advance.

Answer 1

After some hacking and testing, still not manage to customize the button. But this is the closest I can get, by setting the tint color of mail controller.

MFMailComposeViewController *mailController = [[MFMailComposeViewController alloc] init];
mailController.mailComposeDelegate = self;
mailController.navigationBar.tintColor = [UIColor brownColor];
