Xcode9之前
设置状态栏颜色首先在info.plist文件中,加入UIViewControllerBasedStatusBarAppearance = false;
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
让后在delegate didFinishLaunchingWithOptions 方法中加入下面的代码就可以了;
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
[[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
Xcode9之后
xcode9.1我在设置状态栏字体为白色时,按照上面的方法行不通,搜罗了一圈有了结果;
同样在info.plist中,加入 UIViewControllerBasedStatusBarAppearance = true, 注意是true;
<key>UIViewControllerBasedStatusBarAppearance</key>
<true/>
接着新建一个基于 UINavigationController 的类 BaseNavigationController,一个基于 UIViewController 类 BaseViewController ;
BaseNavigationController.m
-(UIViewController *)childViewControllerForStatusBarStyle { return self.topViewController; } -(UIViewController *)childViewControllerForStatusBarHidden { return self.topViewController; }
BaseViewController.m
-(UIStatusBarStyle)preferredStatusBarStyle{ ///这里设置白色 return UIStatusBarStyleLightContent; }
-(BOOL)prefersStatusBarHidden{ return NO; }
在项目中如果新建UINavigationController就继承BaseNavigationController,新建UIViewController就继承BaseViewController,这样就可以实现状态栏字体改变了;如果你是已经有的现有项目,可以扩展UINavigationController和UIViewController,来进行实现;
