Status bar background color

问题

I am trying to make my status bar background color the same as my navigation bar, I was trying to find the answer in google but it does not work clearly for me... Can you please explain how it works and how can I fix it?

回答1:

It looks to me like you have a UINavigationBar up there, which is what's causing the gap at the top. If you are able to, embed your view controller in a UINavigationController instead, then set your navigation item buttons in code. This gives you the same effect, but also automatically ensures the status bar matches the look of its navigation bar.

回答2:

Goto your app info.plist

1) Set View controller-based status bar appearance to NO 2) Set Status bar style to UIStatusBarStyleLightContent

Then Goto your app delegate and paste the following code where you set your Windows's RootViewController.

#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0"))
    {
        UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0,[UIScreen mainScreen].bounds.size.width, 20)];
        view.backgroundColor=[UIColor blackColor];
        [self.window.rootViewController.view addSubview:view];
    }
