iOS 实现更换状态栏的颜色

首先，我们要在plist文件里添加  View controller-based status bar appearance == NO 默认是YES。

然后你写更改状态栏颜色的方法就有效果了

UIStatusBarStyleLightContent为你要设置的颜色

[[UIapplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];

一共有四种情况

    UIStatusBarStyleDefault                                     = 0, // Dark content, for use on light backgrounds

    UIStatusBarStyleLightContent     NS_ENUM_AVAILABLE_IOS(7_0) =1, // Light content, for use on dark backgrounds

    UIStatusBarStyleBlackTranslucent NS_ENUM_DEPRECATED_IOS(2_0,7_0, "Use UIStatusBarStyleLightContent") =1,

    UIStatusBarStyleBlackOpaque      NS_ENUM_DEPRECATED_IOS(2_0,7_0, "Use UIStatusBarStyleLightContent") =2,
