推荐答案

您需要在应用程序委托中添加一个子视图，并根据您的喜好更改颜色。这里是位于 applicationdidfinishLaunchingWithOptions

you need to add a subview in app delegate and change the color to your liking. here is a sample of the code that sits in applicationdidfinishLaunchingWithOptions

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.

    // Override point for customization after application launch.
    if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
        UIView *addStatusBar = [[UIView alloc] init];
        addStatusBar.frame = CGRectMake(0, 0, 320, 20);
        //change this to match your navigation bar or view color or tool bar
        //You can also use addStatusBar.backgroundColor = [UIColor BlueColor]; or any other color
        addStatusBar.backgroundColor = [UIColor colorWithRed:0.973/255. green:0.973/255. blue:0.973/255. alpha:1];
        [self.window.rootViewController.view addSubview:addStatusBar];
    }
    return YES;
}

查看评论。您可以使用 addStatusBar.backGroundColor 中的任何类型的颜色来匹配所需的颜色。注意，这里的红色只是产生一个黑色背景，改变到任何你需要的。对于深灰色，用以下代码替换：

take a look at the comments. you can use any type of color in addStatusBar.backGroundColor to match the color you need. note that the color with red here is just producing a Black background, change that to whatever you need. for dark grey replace that with the following code:

addStatusBar.backgroundColor = [UIColor colorWithRed:85.0/255.0 green:85.0/255.0 blue:85.0/255.0 alpha:1];

编辑：

你可以在之后的 ViewDidLoad 方法中插入以下代码（它将访问您要更改的视图）：super viewDidLoad ];

for changing the status bar color in individual views you simply plug in the following code ( which will access the view you want to change) in ViewDidLoad method right after [super viewDidLoad]; that should change the color of the status bar in just that view you place the code in.

if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0) {
    UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, 0, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:0.973/255. green:0.973/255. blue:0.973/255. alpha:1];
    [self.view addSubview:addStatusBar];

edit1：

要在导航控制器的nag栏顶部添加一个子视图，您必须将子视图的位置设置为两倍，如下所示：

in case of trying to add a subview on top of the nag bar in navigation controller, you have to twice the position of the subview, something like the following:

UIView *addStatusBar = [[UIView alloc] init];
    addStatusBar.frame = CGRectMake(0, -20, 320, 20);
    addStatusBar.backgroundColor = [UIColor colorWithRed:127.0/255. green:0.0/255. blue:127.0/255. alpha:1];
    [self.view addSubview:addStatusBar];
    [self.navigationController.navigationBar addSubview:addStatusBar];

，还需要将子视图添加到导航控制器导航栏的子视图。我将子视图的背景颜色设置为紫色，但您可以更改。

and also you need to add your subview as yet the subview of the navigation controllers' navigation bar. i set the background color of the subview to purple but you can change that.
