设置电池状态栏为白色

1、首先需要再info.plist中添加一项View controller-based status bar appearance为no

2、在需要的地方添加代码

(void)viewWillAppear:(BOOL)animated

{

[super viewWillAppear:animated];

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:NO];

}

(void)viewWillDisappear:(BOOL)animated

{

[super viewWillDisappear:animated];

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault animated:NO];

}
