苹果的通知分为本地通知和远程通知，这里主要说的是远程通知
历史介绍
iOS 3 - 引入推送通知UIApplication 的 registerForRemoteNotificationTypes 与 UIApplicationDelegate 的 application(_:didRegisterForRemoteNotificationsWithDeviceToken:)，application(_:didReceiveRemoteNotification:)
iOS 4 - 引入本地通知scheduleLocalNotification，presentLocalNotificationNow:，application(_:didReceive:)
iOS 5 - 加入通知中心页面
iOS 6 - 通知中心页面与 iCloud 同步
iOS 7 - 后台静默推送application(_:didReceiveRemoteNotification:fetchCompletionHandle:)
iOS 8 - 重新设计 notification 权限请求，Actionable 通知registerUserNotificationSettings(_:)，UIUserNotificationAction 与 UIUserNotificationCategory，application(_:handleActionWithIdentifier:forRemoteNotification:completionHandler:) 等
iOS 9 - Text Input action，基于 HTTP/2 的推送请求UIUserNotificationActionBehavior，全新的 Provider API 等
ios 10 -
- 相同的特性使用类似的API（之前的功能API使用方法类似但是还是稍有改变）
- 内容扩展（支持附件和展示更多内容）
- 本地通知和远程通知操作代码在相同调用路径（合并代理方法）
- 简化代理方法
- 更好的通知管理（支持通知查、改、删；增强本地通知管理，增加日历与地理位置事件的触发）
- 应用内通知展示（之前App在前台的情况下收到通知不会UI展示）
- 在Extensions中规划和操作通知（使更新通知内容和删除误发或过期的通知内容成为可能，另一个重要场景为端到端加密）
- 引入通知Extensions
1.注册通知
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {#pragma clang diagnostic push
#pragma clang diagnostic ignored"-Wdeprecated-declarations"
CGFloat systemVersion = [[UIDevice currentDevice].systemVersion doubleValue];
if (systemVersion < 8.0) { //iOS7之前
[application registerForRemoteNotificationTypes:UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeNewsstandContentAvailability | UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert];
} else if(systemVersion < 10.0) { // iOS7-IOS9
#ifdef __IPHONE_8_0

// action1.identifier = @"action1_identifier";
// action1.title=@"确定";
// action1.activationMode = UIUserNotificationActivationModeForeground;//当点击的时候启动程序
//
// UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc] init]; //第二按钮
// action2.identifier = @"action2_identifier";
// action2.title=@"取消";
// action2.activationMode = UIUserNotificationActivationModeBackground;//当点击的时候不启动程序，在后台处理
// action2.authenticationRequired = YES;//需要解锁才能处理，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略；
// action2.destructive = YES;
//

UNUserNotificationCenter *notificationCenter = [UNUserNotificationCenter currentNotificationCenter];
notificationCenter.delegate = self;
[notificationCenter requestAuthorizationWithOptions:(UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound) completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (granted) {
DLog(@"通知已打开")
} else {
DLog(@"通知没有打开，建议用户去通知中心打开通知")
}
}];
#endif

2.接收到通知
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
DLog(@"iOS6及以下系统，收到通知");
[self dealRemoteNotification:userInfo];
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler NS_AVAILABLE_IOS(7_0)
{
DLog(@"iOS7收到通知");
[self dealRemoteNotification:userInfo];
completionHandler(UIBackgroundFetchResultNewData);
}
- (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification {
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler
{
NSDictionary *userInfo = notification.request.content.userInfo;
[self dealRemoteNotification:userInfo];
}
- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void (^)())completionHandler
{
NSDictionary *userInfo = response.notification.request.content.userInfo;
[self dealRemoteNotification:userInfo];
}
- (void)dealRemoteNotification:(NSDictionary *) userInfo
{
NSDictionary *aps = [userInfo objectForKey:@"aps"];
NSString *alert = [aps objectForKey:@"alert"];
DLog(@"通知内容：%@", alert);
DLog(@"收到推送消息：%@", userInfo);
UIApplicationState state = [UIApplication sharedApplication].applicationState;
switch (state) {
// app正在前端运行
case UIApplicationStateActive:
{
DLog(@"app active时可以回调此方法，但是手机通知栏没有通知跟声音");
}
break;
case UIApplicationStateBackground:
{
DLog(@"UIApplicationStateBackground");
}
break;
// app 在后台运行时点击远程通知
case UIApplicationStateInactive:
{
DLog(@"点击通知图标 时点通知启动");
}
break;
default:
break;
}
}
3.点击通知
如果APP处于未启动状态，点击通知栏启动APP，此时
- 若用户直接启动，lauchOptions内无数据;
- 若由其他应用程序通过openURL:启动，则UIApplicationLaunchOptionsURLKey对应的对象为启动URL（NSURL）,UIApplicationLaunchOptionsSourceApplicationKey对应启动的源应用程序的bundle ID (NSString)；
- 若由本地通知启动，则UIApplicationLaunchOptionsLocalNotificationKey对应的是为启动应用程序的的本地通知对象(UILocalNotification)；
- 若由远程通知启动，则UIApplicationLaunchOptionsRemoteNotificationKey对应的是启动应用程序的的远程通知信息userInfo（NSDictionary）；
- 其他key还有UIApplicationLaunchOptionsAnnotationKey,UIApplicationLaunchOptionsLocationKey,
UIApplicationLaunchOptionsNewsstandDownloadsKey。
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *url = [options objectForKey:UIApplicationLaunchOptionsURLKey];
if(url)
{
}
NSString *bundleId = [options objectForKey:UIApplicationLaunchOptionsSourceApplicationKey];
if(bundleId)
{
}
UILocalNotification * localNotify = [options objectForKey:UIApplicationLaunchOptionsLocalNotificationKey];
if(localNotify)
{
}
NSDictionary * userInfo = [options objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if(userInfo)
{
}
}
