###一 了解苹果推送 苹果推送分为本地推送、在线推送、离线推送三种模式， 本地推送是使用一套本地推送的机制和网络服务器无关，可用于闹钟之类的需求，在线推送是应用处于前台模式，使用APP自己的长链接推送 ，和APP设置通知的开关没有关系 ，离线推送就是APNs推送了，app服务器发送推送请求到APNs服务器，APNs服务器发送推送到指定的设备，离线推送就和APP设置的通知开关有关系了。以微信为例，当微信处于前台时是进入微信自己的长链接推送通道，和手机APP设置推送是否开启无关， 处于后台模式、锁屏或者kill了则使用APNs通道，通知关闭则收不到推送了 ####1 远程推送 远程推送又可以可以分为静默推送和正常推送 正常推送用户会收到推送内容、声音，应用处于后台或者kill点击推送内容进入APP后才会会进入
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
静默推送是一种特殊的远程推送，没有推送内容声音，不用点击推送内容也不用进入APP就会执行，用户毫无感觉
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler
静默推送是iOS7.0之后推出的,又被称为：Background Remote Notification（后台远程推送）可以不用打开APP就可以运行代码，（大多是用户毫无察觉的处理 服务器传到APP的数据，更新APP内容） ####2本地推送 本地推送和远程推送一样都是通知APP做事情，远程推送是需要联网的，只有联网才能和苹果服务器APNs建立长链接、接受APNs的消息，本地推送是不需要联网的，APP内部实现推送功能，本地推送的目标是安装了APP的设备，受APP在该设备的通知是否开启影响。最常用的就是闹钟APP 注意：iOS8 - iOS10的本地推送：当应用处于前台是不会有横幅或者弹框，用户无感知，可以在didReceiveLocalNotification 回调中处理弹框使用户感知，让应用处于后台才会有横幅和弹框铃声等， 推送的注册和回调，64条是苹果官方设置的上限。
-(void)registerAPNs:(UIApplication *)application
{
// iOS8~iOS10 与 iOS10之后的系统本地推送是不同的
if (@available(iOS 10.0, *)) {
UNUserNotificationCenter *unCenter = [UNUserNotificationCenter currentNotificationCenter];
unCenter.delegate = self;
[unCenter requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge | UNAuthorizationOptionSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(@"注册成功");
dispatch_async(dispatch_get_main_queue(), ^{
[[UIApplication sharedApplication] registerForRemoteNotifications];
});
}
}];
[unCenter getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * _Nonnull settings) {
NSLog(@"regist success settting is =====+%@",settings);
}];
} else {

设置推送内容 fireDate、timeZone、repeatInterval和repeatCalendar的含义 1 fireDate是UILocalNotification的激发的确切时间。 2 timeZone是UILocalNotification激发时间所根据的时区，如果设置为nil的话，那么UILocalNotification将在一段时候后被激发，而不是某一个确切时间被激发。 3 repeatInterval是UILocalNotification被重复激发之间的时间差，不过时间差是完全根据日历单位（NSCalendarUnit）的，例如每周激发的单位，NSWeekCalendarUnit，如果不设置的话，将不会重复激发。 4 repeatCalendar是UILocalNotification重复激发所使用的日历单位需要参考的日历，如果不设置的话，系统默认的日历将被作为参考日历。 5添加category按钮，和用户点击推送内容进行交互 UNTextInputNotificationAction：用户输入text，可以在didReceiveNotificationResponse回调中获取text内容 UNNotificationAction：根据需求自定义推送点击按钮

###3远程推送 ######1 远程推送原理： 客户端注册远程推送发送Token key ，APNs服务器根据Token key 下发给客户端deviceToken； 客户端把DeviceToken发送给自己的服务器，自己的服务器发送推送消息给APNs服务器，APNs服务器将消息发给DeviceToken对应设备上的客户端，如下图所示
{
"aps" : {
"alert" : { // string or dictionary
"title" : "string"
"body" : "string",
"title-loc-key" : "string or null"
"title-loc-args" : "array of strings or null"
"action-loc-key" : "string or null"
"loc-key" : "string"
"loc-args" : "array of strings"
"launch-image" : "string"
},
"badge" : number,
"sound" : "string"
"content-available" : number;
"category" : "string"
},
}
aps：推送消息必须有的key alert：推送消息包含此key值，系统根据设备显示弹框 badge：在APP图标右上角显示的消息数目，缺少此key，消息数目不会改变，消除标记时把此key对应的value设置为0 sound：设置推送声音的key值，value 为default时会用系统默认的提示音 content-available：此key设置为1时，在收到消息之前会进入extent server 的回调方法，修改显示的值 category：UNNotificationCategory的identifier， 用户可操作的类型的key值 title：推送消息的标题：iOS8.2之后 body：推送内容 title-loc-key：功能类似title，附加功能是国际化，iOS8.2之后 title-loc-args：配合title-loc-key字段使用，iOS8.2之后 action-loc-key：可操作通知类型的key loc-key：参考title-loc-key loc-args：参考title-loc-args launch-image：点击推送消息或者移动时间滑块时显示的图片，如果缺少此key值，会加载App默认的启动图片 自定义ke值
{
"aps" : {
"alert" : "Provider push messag.",
"badge" : 9,
"sound" : "toAlice.aiff"
},
"Id" : 1314, // 自定义key值
"type" : "customType" // 自定义key值
}
1模拟器不能接受推送，没有deviceToken，必须真机
