Question

我不确定我的应用程序中有哪些更改，但我无法再清除徽章编号。

我把代码放在下面的代码中：

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];

在：

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

我也尝试过：

application.applicationIconBadgeNumber = 0;

它不会工作，即使它之前做过，请咨询

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;
}

Answer 1

您以didFinishLaunchingWithOptions方式调用它，只有在启动应用时才会被清除。

您是否尝试过多任务菜单中的应用程序并再次启动它？

同时尝试在setApplicationIconBadgeNumber中移动applicationDidBecomeActive。

Answer 2

将它设置为-1，如下所示：

application.applicationIconBadgeNumber = -1;

或者像这样：

[[UIApplication sharedApplication] setApplicationIconBadgeNumber:-1];

徽章编号不会清楚
