ios开发中的两种消息通知机制详解

iOS中通知机制又叫消息机制，其包括两类：一类是本地通知;另一类是推送通知，也叫远程通知。两种通知在iOS中的表现一致，可以通过横幅或者弹出提醒两种形式告诉用户，并且点击通知可以会打开应用程序，但是实现原理却完全不同。

本地通知

1.创建UILocalNotification。

2.设置处理通知的时间fireDate。

3.配置通知的内容：通知主体、通知声音、图标数字等。

4.配置通知传递的自定义数据参数userInfo(这一步可选)。

5.调用通知，可以使用scheduleLocalNotification:按计划调度一个通知，也可以使用presentLocalNotificationNow立即调用通知。

下面就以一个程序更新后用户长期没有使用的提醒为例对本地通知做一个简单的了解。在这个过程中并没有牵扯太多的界面操作，所有的逻辑都在AppDelegate中：进入应用后如果没有注册通知，需要首先注册通知请求用户允许通知;一旦调用完注册方法，无论用户是否选择允许通知此刻都会调用应用程序的- (void)application:(UIApplication )application didRegisterUserNotificationSettings:(UIUserNotificationSettings )notificationSettings代理方法，在这个方法中根据用户的选择：如果是允许通知则会按照前面的步骤创建通知并在一定时间后执行。

1.请求获得用户允许通知的效果。

2.应用退出到后弹出通知的效果。

3.锁屏状态下的通知效果(从这个界面可以看到alertAction配置为“打开应用”)。

注意：

  • 在使用通知之前必须注册通知类型，如果用户不允许应用程序发送通知，则以后就无法发送通知，除非用户手动到iOS设置中打开通知。

  • 本地通知是有操作系统统一调度的，只有在应用退出到后台或者关闭才能收到通知。(注意：这一点对于后面的推送通知也是完全适用的。 )

  • 通知的声音是由iOS系统播放的，格式必须是Linear PCM、MA4(IMA/ADPCM)、µLaw、aLaw中的一种，并且播放时间必须在30s内，否则将被系统声音替换，同时自定义声音文件必须放到main boundle中。

  • 本地通知的数量是有限制的，最近的本地通知最多只能有64个，超过这个数量将被系统忽略。

  • 如果想要移除本地通知可以调用UIApplication的cancelLocalNotification:或cancelAllLocalNotifications移除指定通知或所有通知。

从上面的程序可以看到userInfo这个属性我们设置了参数，那么这个参数如何接收呢?

在iOS中如果点击一个弹出通知(或者锁屏界面滑动查看通知)，默认会自动打开当前应用。由于通知由系统调度那么此时进入应用有两种情况：如果应用程序已经完全退出那么此时会调用- (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions方法;如果此时应用程序还在运行(无论是在前台还是在后台)则会调用-(void)application:(UIApplication )application didReceiveLocalNotification:(UILocalNotification )notification方法接收消息参数。当然如果是后者自然不必多说，因为参数中已经可以拿到notification对象，只要读取userInfo属性即可。如果是前者的话则可以访问launchOptions中键为UIApplicationLaunchOptionsLocalNotificationKey的对象，这个对象就是发送的通知，由此对象再去访问userInfo。为了演示这个过程在下面的程序中将userInfo的内容写入文件以便模拟关闭程序后再通过点击通知打开应用获取userInfo的过程。
