iOS电池栏的设置

设置电池栏为白色

在Appdelegate里
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
同时info.plist添加
View controller-based status bar appearance = NO

启动时隐藏电池栏

设置info.plist
Status bar is initially hidden = YES
但是隐藏了电池栏会导致电池栏不显示,所以需要在Appdelegate里添加
[[UIApplication sharedApplication]setStatusBarHidden:NO withAnimation:UIStatusBarAnimationNone];
