iOS 如何启动app使logo右上角的数字隐藏

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary
*)launchOptions

中添加一下代码即可

if([[UIDevice
currentDevice].systemVersion
floatValue] >= 8.0){

        UIUserNotificationSettings *settings = [UIUserNotificationSettings
settingsForTypes:UIUserNotificationTypeBadge
categories:nil];

        

        [[UIApplication
sharedApplication]
registerUserNotificationSettings:settings];

        

        UIApplication *app = [UIApplication
sharedApplication];

        // 应用程序右上角数字

        app.applicationIconBadgeNumber =
0;

    }
