一直更新了iOS8，但是一直没有开始研究这个iOS8，今天因为项目用到了推送，于是体验了iOS8的推送，先讲讲这个推送。目前分为四个推送：用户推送，本地推送，远程推送，地理位置推送。
用户推送
我们先开始讲这个用户推送,我们要使用之前必须先注册这个推送，用户要允许这个程序进行推送
注册过程：
1if (IS_IOS8) { 2 //1.创建消息上面要添加的动作(按钮的形式显示出来) 3 UIMutableUserNotificationAction *action = [[UIMutableUserNotificationAction alloc] init]; 4 action.identifier = @"action";//按钮的标示 5 action.title=@"Accept";//按钮的标题 6 action.activationMode = UIUserNotificationActivationModeForeground;//当点击的时候启动程序 7 // action.authenticationRequired = YES; 8 // action.destructive = YES; 9 10 UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc] init]; 11 action2.identifier = @"action2"; 12 action2.title=@"Reject"; 13 action2.activationMode = UIUserNotificationActivationModeBackground;//当点击的时候不启动程序，在后台处理 14 action.authenticationRequired = YES;//需要解锁才能处理，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略； 15 action.destructive = YES; 16 17 //2.创建动作(按钮)的类别集合 18 UIMutableUserNotificationCategory *categorys = [[UIMutableUserNotificationCategory alloc] init]; 19 categorys.identifier = @"alert";//这组动作的唯一标示,推送通知的时候也是根据这个来区分 20 [categorys setActions:@[action,action2] forContext:(UIUserNotificationActionContextMinimal)]; 21 22 //3.创建UIUserNotificationSettings，并设置消息的显示类类型 23 UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:[NSSet setWithObjects:categorys, nil nil]]; 24 [application registerUserNotificationSettings:notiSettings]; 25 26 }else{ 27 [application registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound]; 28 } 29 30 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings 31{ 32// UIUserNotificationSettings *settings = [application currentUserNotificationSettings]; 33// UIUserNotificationType types = [settings types]; 34// //只有5跟7的时候包含了 UIUserNotificationTypeBadge 35// if (types == 5 || types == 7) { 36// application.applicationIconBadgeNumber = 0; 37// } 38 //注册远程通知 39 [application registerForRemoteNotifications]; 40}
我们现在仅仅是注册了通知的设置，还要注册推送通知的行为，在iOS8中，行为能直接在推送消息进行，如回复消息，拒绝消息等总结就是三个方法进行注册
我们如何能进行这些行为，首先我们需注册这些行为。
-
Actions
-
1 UIMutableUserNotificationAction *acceptAction = [[UIMutableUserNotificationAction alloc] init]; 2 acceptAction.identifier = @"RickAction"; 3 acceptAction.title = @"Accept"; 4 acceptAction.activationMode = UIUserNotificationActivationModeBackground; 5 acceptAction.destructive = NO; 6 acceptAction.authenticationRequired = NO; -
Categories
-
1 UIMutableUserNotificationCategory *inviteCategory = [[UIMutableUserNotificationCategory alloc] init]; 2 inviteCategory.identifier = @"INVITE_CATEGORY"; 3 [inviteCategory setActions:@[acceptAction] forContext:UIUserNotificationActionContextDefault];
1我们需要注意这个UIUserNotificationActionContextDefault,如果我们使用这个，我们会得到这个推送行为，Maybe和Accept 2 3我们还可以使用UIUserNotificationActionContextMinimal得到的是Decline和Accept行为 4 5 6 7
-
Settings
在这些行为注册之后，我们加上之前提到的推送设置就完成了注册推送的这个流程了
-
1 NSSet *categories = [NSSet setWithObjects:inviteCategory, nil nil]; 2 UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert ; 3 UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:categories]; 4 [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];
远程推送
1---- 2 3远程推送，所有消息大小不超过2KB,我们获取远程推送的json格式的消息，解析这个消息就是我们的远程推送了：
-
1 { 2 “aps”: { 3 "content-available": 1, 4 "alert": "This is the alert text", 5 "badge": 1, 6 "sound": "default" 7 } 8 } -
若要使用远程推送，满足两个条件：一、用户需要调用注册用户推送registerUserNotificationSettings;二、在info.plist文件中UIBackgroundModes必须包含远程通知。
-
[[UIApplication sharedApplication] registerForRemoteNotifications]; -
1 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 2 NSString *token=[NSString stringWithFormat:@"%@",deviceToken]; 3 token=[token stringByReplacingOccurrencesOfString:@"<" withString:@""]; 4 token=[token stringByReplacingOccurrencesOfString:@">" withString:@""]; 5 token=[token stringByReplacingOccurrencesOfString:@" " withString:@""]; 6 7 } -
1 - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { 2 3 }
iOS7通知代理方法
1 2 3后来又增加了本地通知的代理方法 4 5 6 7iOS8的推送代理方法只有两个了 8 9
-
1 - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler 2 { 3 } 4 5 - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler 6 { 7 } 8 9 - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler 10 { 11 if ([identifier isEqualToString:@"RickAction"]) { 12 [self handleAcceptActionWithNotification:notification]; 13 } 14 completionHandler(); 15 } 16 17 - (void)handleAcceptActionWithNotification:(UILocalNotification*)notification 18 { 19 }
地理位置推送
这个推送是新的API才有的特性,必须配合CLLocation定位一起使用。
-
1 //Location Notification 2 CLLocationManager *locMan = [[CLLocationManager alloc] init]; 3 locMan.delegate = self; 4 [locMan requestWhenInUseAuthorization]; 5 6 #pragma mark - CLLocationManager 7 8 - (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status 9 10 { 11 BOOL canUseLocationNotifications = (status == kCLAuthorizationStatusAuthorizedWhenInUse); 12 if (canUseLocationNotifications) { 13 [self startShowLocationNotification]; 14 } 15 } 16 - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification 17 18 { 19 CLRegion *region = notification.region; 20 if (region) { 21 } 22 } 23 24 - (void)startShowLocationNotification 25 26 { 27 CLLocationCoordinate2D local2D ; 28 local2D.latitude = 123.0; 29 local2D.longitude = 223.0; 30 UILocalNotification *locNotification = [[UILocalNotification alloc] init]; 31 locNotification.alertBody = @"你接收到了"; 32 locNotification.regionTriggersOnce = YES; 33 locNotification.region = [[CLCircularRegion alloc] initWithCenter:local2D radius:45 identifier:@"local-identity"]; 34 [[UIApplication sharedApplication] scheduleLocalNotification:locNotification]; 35 }
如果没有开启Core Location 那么上面的didReceiveLocalNotification不会被调用
1最后再总结一下，整个推送流程我觉得是这样子的，先注册推送，然后推送消息，客户端接收推送消息，执行推送行为。如果有错误，还请在文章下面评论，欢迎指正。 2 3 4 5 6这个博客写的也不错：[http://blog.csdn.net/yujianxiang666/article/details/35260135](https://www.oschina.net/action/GoToLink?url=http%3A%2F%2Fblog.csdn.net%2Fyujianxiang666%2Farticle%2Fdetails%2F35260135)
