我试图改变背景颜色的MFMailComposeViewController在iOS7但我不能使它发挥作用.

我正在使用以下剪辑:

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

if([picker.navigationBar respondsToSelector:@selector(barTintColor)]) {
    // iOS7
    picker.navigationBar.barTintColor = READER_NAVIGATION_BAR_BACKGROUND_COLOR;
    // Set back button arrow color
    [picker.navigationBar setTintColor:READER_NAVIGATION_BAR_BACK_BUTTON_ARROW_COLOR];

    // Set Navigation Bar Title Color
    [picker.navigationBar setTitleTextAttributes:[NSDictionary dictionaryWithObject:READER_NAVIGATION_BAR_TITLE_NORMAL_FONT_COLOR forKey:UITextAttributeTextColor]];

    // Set back button color
    [[UIBarButtonItem appearanceWhenContainedIn:[UINavigationBar class], nil] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:READER_NAVIGATION_BAR_BUTTONS_FONT_COLOR, UITextAttributeTextColor,nil] forState:UIControlStateNormal];

} 

有谁知道如何改变iOS7中的bakcground颜色MFMailComposeViewController？

我一直在寻找,我找不到它.

什么是在分组的UITableView的背景色iOS7在RGB？
