ios - 在 MFMailComposeViewController 中禁用 NavBar 半透明

Question

我的第一个 View 嵌入在导航 Controller 中，我将其半透明属性设置为 NO。这给了我想要的纯绿色，状态栏是白色。但是，当我打开 MFMailComposeViewController 时，半透明属性设置回 YES，状态栏返回黑色。

如何移除半透明并将状态栏设置回白色？下面是我的代码。

- (void)viewDidLoad
{
    [super viewDidLoad];

    self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

    self.navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
    [self.navigationController.navigationBar setTranslucent:NO];
}

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.section == 1) {
        if (indexPath.row == 0) {
            NSArray *toRecipents = [NSArray arrayWithObject:@"email goes here"];
            MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
            mc.mailComposeDelegate = self;
            [mc.navigationBar setTintColor:[UIColor whiteColor]];

            [mc.navigationController.navigationBar setTranslucent:NO];

            [mc setSubject:@"Inquiry"];
            [mc setMessageBody:@"Hi, " isHTML:NO];
            [mc setToRecipients:toRecipents];
            [self presentViewController:mc animated:YES completion:NULL];
        }
    }
}

这对我有用:

[[UINavigationBar appearance] setTranslucent:NO];
