objective-c - 关于ios状态栏颜色变化

Question

• (void)viewWillAppear:(BOOL)animated {

  [super viewWillAppear:animated];
  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

  }

• (void)viewWillDisappear:(BOOL)animated {

  [super viewWillDisappear:animated];
  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleDefault];

  }

首先我知道这样是进入改成白色,切换到其他页面变成黑色
问题来了:tabbar上2个页面都这么写.2个页面同时这样写的话.切换过去的时候就是黑色不会变成白色。
(ps:一个是首页,一个是个人中心)

Answer 1

• First of all: format your question so that others can see it and they will be willing to answer your question.

• Secondly: Please tell me clearly, what UITabBar 还是 UITabBarController are you using?

Answer 2

There are two uiviewcontrollers in UITabBarController that are written like this...Homepage and Personal Center. But problems will occur when the homepage and Personal Center are switched...
