在ios8中,直接设置application badge value会出错

 1 [[UIApplication sharedApplication] setApplicationIconBadgeNumber:count]; 

曝出”Attempting to badge the application icon but haven‘t received permission from the user to badge the application“的错误。

  原因是因为在ios8中,设置应用的application badge value需要得到用户的许可。使用如下方法咨询用户是否许可应用设置application badge value

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

程序运行时,会弹出提示框给用户

 

 

iOS8中新增了通知授权后的回调:
– (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
问题解决
把所有
– (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中的-[UIApplication setApplicationIconBadgeNumber:]
移到
– (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
回调中
