1.本地通知需要当应用在后台时执行，比如放在applicationDidEnterBackground方法里；

2.需要注册通知

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {[self notificationSetting];return YES;}/** *推送设置 */-(void)notificationSetting{    // ios8后，需要添加这个注册，才能得到授权    if ([[UIApplication sharedApplication] respondsToSelector:@selector(registerUserNotificationSettings:)]) {        UIUserNotificationType type =  UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound;        UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:type                                                                                 categories:nil];        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];            }}- (void)applicationDidEnterBackground:(UIApplication *)application {    [self execLocalNofitication];}-(void)execLocalNofitication{    UILocalNotification *notification = [[UILocalNotification alloc] init];    if (notification) {        // 设置触发通知的时间        NSDate *fireDate = [NSDate dateWithTimeIntervalSinceNow:2];        notification.fireDate = fireDate;        // 时区        notification.timeZone = [NSTimeZone defaultTimeZone];        // 设置重复的间隔        notification.repeatInterval = 0;        // 通知内容        notification.alertBody = nil;        notification.applicationIconBadgeNumber = -99;        // 通知被触发时播放的声音        notification.soundName = nil;        // 执行通知注册        [[UIApplication sharedApplication] scheduleLocalNotification:notification];    }}
