ios - 角标(Badge)号码不会清除

Question

我不确定我在应用程序中更改了什么，但我无法再清除角标(Badge)编号。

我把代码写成下面的代码:

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];

在:

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

我也尝试过:

application.applicationIconBadgeNumber = 0;

现在不行了，虽然以前可以，请指教

完整代码:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Override point for customization after application launch.
    [[UINavigationBar appearance] setTintColor:[UIColor blackColor]];

    //Let the device know we want to receive push notifications
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:
     (UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeBadge)];

    NSLog(@"didFinishLaunchingWithOptions");

    //application.applicationIconBadgeNumber = 0;
    //[[UIApplication sharedApplication] setApplicationIconBadgeNumber:-1];
    [[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];

    return YES;
}

您在 didFinishLaunchingWithOptions 中调用它，这样它只会在启动应用程序时被清除。

您是否尝试过从多任务菜单中关闭应用程序并再次启动它？

也尝试在 applicationDidBecomeActive 中移动 setApplicationIconBadgeNumber。
