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：
if (IS_IOS8) {
//1.创建消息上面要添加的动作(按钮的形式显示出来)
UIMutableUserNotificationAction *action = [[UIMutableUserNotificationAction alloc] init];
action.identifier = @"action";//按钮的标示
action.title=@"Accept";//按钮的标题
action.activationMode = UIUserNotificationActivationModeForeground;//当点击的时候启动程序
// action.authenticationRequired = YES;
// action.destructive = YES;
UIMutableUserNotificationAction *action2 = [[UIMutableUserNotificationAction alloc] init];
action2.identifier = @"action2";
action2.title=@"Reject";
action2.activationMode = UIUserNotificationActivationModeBackground;//当点击的时候不启动程序，在后台处理
action.authenticationRequired = YES;//需要解锁才能处理，如果action.activationMode = UIUserNotificationActivationModeForeground;则这个属性被忽略；
action.destructive = YES;
//2.创建动作(按钮)的类别集合
UIMutableUserNotificationCategory *categorys = [[UIMutableUserNotificationCategory alloc] init];
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
[categorys setActions:@[action,action2] forContext:(UIUserNotificationActionContextMinimal)];
//3.创建UIUserNotificationSettings，并设置消息的显示类类型
UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:[NSSet setWithObjects:categorys, nil nil]];
[application registerUserNotificationSettings:notiSettings];
}else{
[application registerForRemoteNotificationTypes: UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound];
}
- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings
{
// UIUserNotificationSettings *settings = [application currentUserNotificationSettings];
// UIUserNotificationType types = [settings types];
// //只有5跟7的时候包含了 UIUserNotificationTypeBadge
// if (types == 5 || types == 7) {
// application.applicationIconBadgeNumber = 0;
// }
//注册远程通知
[application registerForRemoteNotifications];
}
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
UIMutableUserNotificationAction *acceptAction = [[UIMutableUserNotificationAction alloc] init]; acceptAction.identifier = @"RickAction"; acceptAction.title = @"Accept"; acceptAction.activationMode = UIUserNotificationActivationModeBackground; acceptAction.destructive = NO; acceptAction.authenticationRequired = NO;Categories
UIMutableUserNotificationCategory *inviteCategory = [[UIMutableUserNotificationCategory alloc] init]; inviteCategory.identifier = @"INVITE_CATEGORY"; [inviteCategory setActions:@[acceptAction] forContext:UIUserNotificationActionContextDefault];
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
我们还可以使用UIUserNotificationActionContextMinimal得到的是Decline和Accept行为
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
NSSet *categories = [NSSet setWithObjects:inviteCategory, nil nil]; UIUserNotificationType types = UIUserNotificationTypeBadge | UIUserNotificationTypeSound | UIUserNotificationTypeAlert ; UIUserNotificationSettings *mySettings = [UIUserNotificationSettings settingsForTypes:types categories:categories]; [[UIApplication sharedApplication] registerUserNotificationSettings:mySettings];远程推送
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：
{ “aps”: { "content-available": 1, "alert": "This is the alert text", "badge": 1, "sound": "default" } }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];- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { NSString *token=[NSString stringWithFormat:@"%@",deviceToken]; token=[token stringByReplacingOccurrencesOfString:@"<" withString:@""]; token=[token stringByReplacingOccurrencesOfString:@">" withString:@""]; token=[token stringByReplacingOccurrencesOfString:@" " withString:@""]; }- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { }iOS7通知代理方法
后来又增加了本地通知的代理方法
iOS8的推送代理方法只有两个了
- (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler { } - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forRemoteNotification:(NSDictionary *)userInfo completionHandler:(void (^)())completionHandler { } - (void)application:(UIApplication *)application handleActionWithIdentifier:(NSString *)identifier forLocalNotification:(UILocalNotification *)notification completionHandler:(void (^)())completionHandler { if ([identifier isEqualToString:@"RickAction"]) { [self handleAcceptActionWithNotification:notification]; } completionHandler(); } - (void)handleAcceptActionWithNotification:(UILocalNotification*)notification { }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。
//Location Notification CLLocationManager *locMan = [[CLLocationManager alloc] init]; locMan.delegate = self; [locMan requestWhenInUseAuthorization]; #pragma mark - CLLocationManager - (void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status { BOOL canUseLocationNotifications = (status == kCLAuthorizationStatusAuthorizedWhenInUse); if (canUseLocationNotifications) { [self startShowLocationNotification]; } } - (void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification { CLRegion *region = notification.region; if (region) { } } - (void)startShowLocationNotification { CLLocationCoordinate2D local2D ; local2D.latitude = 123.0; local2D.longitude = 223.0; UILocalNotification *locNotification = [[UILocalNotification alloc] init]; locNotification.alertBody = @"你接收到了"; locNotification.regionTriggersOnce = YES; locNotification.region = [[CLCircularRegion alloc] initWithCenter:local2D radius:45 identifier:@"local-identity"]; [[UIApplication sharedApplication] scheduleLocalNotification:locNotification]; }如果没有开启Core Location 那么上面的didReceiveLocalNotification不会被调用
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。
