IOS 本地消息推送

1、第一步先注册推送
在AppDelegate.m编写一个推送注册方法如下：
- (void)registerLocalPush{    UILocalNotification *localNotifi = [UILocalNotification new];    [[UIApplication sharedApplication] scheduleLocalNotification:localNotifi];    /*     UIUserNotificationTypeBadge   = 1 << 0, // the application may badge its icon upon a notification being received     UIUserNotificationTypeSound   = 1 << 1, // the application may play a sound upon a notification being received     UIUserNotificationTypeAlert   = 1 << 2, // the application may display an alert upon a notification being     */    UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert categories:nil];        [[UIApplication sharedApplication] registerUserNotificationSettings:settings];}2、在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions函数中调用如下：- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.    [self registerLocalPush];    return YES;}3、设置推送时间
- (void)pushLocalNotifi{    // 1.创建通知    UILocalNotification *localNotification = [[UILocalNotification alloc] init];    // 2.设置通知的必选参数    // 设置通知显示的内容    localNotification.alertBody = @"推送显示的信息";    // 设置通知的发送时间,单位秒，在多少秒之后推送    localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow:10];    //解锁滑动时的事件    localNotification.alertAction = @"XXOOXX";    //收到通知时App icon的角标    localNotification.applicationIconBadgeNumber = 0;    //推送是带的声音提醒，设置默认的字段为UILocalNotificationDefaultSoundName    localNotification.soundName = UILocalNotificationDefaultSoundName;    //设置推送自定义声音格式
    //localNotification.soundName = @"文件名.扩展名";
    //循环次数    localNotification.repeatInterval = kCFCalendarUnitDay;    // 3.发送通知(根据项目需要使用)    // 方式一: 根据通知的发送时间(fireDate)发送通知    [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];}
4、调用推送时间设置
- (IBAction)clickLocalPush:(id)sender{    [self pushLocalNotifi];}
