重写NavBar在其他的文件里设置状态栏一直没有用,只有在NavBar设置才能用
In my iPhone application built with Xcode 5 for iOS 7 I set UIViewControllerBasedStatusBarAppearance=YES in info.plist, and in my ViewController I have this code:
-(UIStatusBarStyle) preferredStatusBarStyle{
returnUIStatusBarStyleLightContent;
}还有在plsit里面设置就能用了
[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;
加入这段代码就可以了,
