当尝试设置通知徽章但未获得用户授权时，iOS应用会报错。解决此问题需在AppDelegate.m的didFinishLaunchingWithOptions方法中添加注册用户通知设置的代码，如下所示：设置UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert，并调用registerUserNotificationSettings方法。

没有注册会报错：

with a badge number but haven't received permission from the user to badge ......

解决方法：在appdelegate.m文件里didFinishLaunchingWithOptions方法添加注册，如下：

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

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

[[UIApplication sharedApplication] registerUserNotificationSettings:settings];

return YES;

}
