cancelAllLocalNotifications并不在当前消息循环立即生效,在iOS8 iphone5下的测试代码如下:

- (void)cancelLocalNotificationsAndClearBadge
{
    UIApplication *app = [UIApplication sharedApplication];
    app.applicationIconBadgeNumber = 0;
    [app cancelAllLocalNotifications];
#ifdef DEBUG
    NSLog(@"after cancelAllLocalNotifications:%@", app.scheduledLocalNotifications);
#endif
}

打印log表面数组中还是有值的。

而使用如下方法:

可以使得立即取值时,得到正确的空数组:

- (void)cancelLocalNotificationsAndClearBadge
{
    UIApplication *app = [UIApplication sharedApplication];
    app.applicationIconBadgeNumber = 0;
    app.scheduledLocalNotifications = nil;
//    [app cancelAllLocalNotifications];
#ifdef DEBUG
    NSLog(@"after cancelAllLocalNotifications:%@", app.scheduledLocalNotifications);
#endif
}
