如何在UINavigationController上设置背景颜色（tintColor）

Question

我希望你能帮我设置控制器的背景颜色。

奇怪的是，当我在Xcode 4.5.2中构建我的代码时，它看起来如下图所示。正如你可以看到背景颜色消失了它应该是（黄色）作为下一张图片

当我在Xcode 4.3.3中构建代码时，它看起来如下图所示。这就是它的外观。

我的代码是这样的：

------------------ InstantCabAppDelegate.m文件----------- START -------

//InstantCabAppDelegate.m file

orderController = [[OrderController2 alloc] initWithNibName:@"Order2" bundle:nil];
UINavigationController* firstnavigationController = [[UINavigationController alloc] initWithRootViewController:orderController];

------------------ OrderController2.m文件----------- START -------

//OrderController2.m file

- (void)viewDidLoad 
{   
    [super viewDidLoad];

    [self.tableView setBackgroundColor:TABLE_VIEW_BACKGROUND_COLOR];
    [self.tableView setSeparatorColor:TABLE_VIEW_SEPARATOR_COLOR];
    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];

    self.parentViewController.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"background-nologo"]];

    UIView *logoParentView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 75)];
    UIImageView *logoView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"logo_order_page"]];
    CGRect logoViewFrame = logoView.frame;
    logoViewFrame.origin.x = (self.view.frame.size.width / 2) - (logoViewFrame.size.width / 2);
    logoViewFrame.origin.y = 8;
    [logoView setFrame:logoViewFrame];
    [logoParentView addSubview:logoView];

    self.tableView.tableHeaderView = logoParentView;
    self.tableView.rowHeight = 50;

    [self.navigationController.navigationBar setTintColor:NAVIGATION_BAR_TINT_COLOR];

    [[MyLocation singleton] setDelegate:self];
    [self reset];

    UIView *footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.frame.size.width, 50)];

    UIButton *orderButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [orderButton setFrame:CGRectMake(5, 0, footerView.frame.size.width - 10, 50)];

    [orderButton setBackgroundImage:[UIImage imageNamed:@"yellow_btn"] forState:UIControlStateNormal];
    [orderButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [orderButton setTitle:AMLocalizedString(@"kOrderOrderTaxiAlt", @"") forState:UIControlStateNormal];

    [[orderButton titleLabel] setFont:[UIFont boldSystemFontOfSize:orderButton.titleLabel.font.pointSize]];
    [orderButton addTarget:self action:@selector(checkOrder) forControlEvents:UIControlEventTouchUpInside];
    [footerView addSubview:orderButton];
    [self.tableView setTableFooterView:footerView];

    isShowingModalViewController = NO;
}

我是从Apple支持中得到的：

当表格视图的样式设置为UITableViewStyleGrouped时，UITableView会将背景视图应用于自身。背景视图用于绘制与该样式表视图关联的默认模式，但它也包含已设置的任何自定义背景颜色。您可以通过调用self.tableView.backgroundView = nil来删除此背景视图;来自viewDidLoad。这样做会使您的自定义背景颜色再次可见。
