iOS(本地通知与远程通知)

iOS 推送通知有两种:本地推送、远程推送.

本地推送 :  在不需要联网的情况下，由APP发出推送,常用于某一时刻的通知,如闹钟。本地通送有局限性在于当APP处于后台或者退出时就无法发出通知。

远程推送:   APNs和第三方推送,第三方推送最终也需要APNs转发,

本地推送实现
　　注册通知:

float sysVer = [[UIDevice currentDevice].systemVersion floatValue];

    if (sysVer < 10) {

        //设置通知类型 弹框、脚标、声音

        UIUserNotificationSettings* setting = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];

        [[UIApplication sharedApplication] registerUserNotificationSettings:setting];

    }else{

        UNUserNotificationCenter* center =[UNUserNotificationCenter currentNotificationCenter];

        [center requestAuthorizationWithOptions:(UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {

            if (granted) {

                NSLog(@"通知注册成功");

            }

        }];

    }

　　发送通知:
　　　　

float sysVer = [[UIDevice currentDevice].systemVersion floatValue];

    if(sysVer < 10){

        UILocalNotification* local = [[UILocalNotification alloc] init];

        //给这些属性赋值才能让通知有特定的内容

        [email protected]"航海王:One Piece";

        //特定的时间让显示出来()

        NSString* dateStr = @"2016-12-01 16:30:00";

        NSDateFormatter* dateFormatter = [[NSDateFormatter alloc]init];

        dateFormatter.dateFormat = @"yyyy-MM-dd hh:mm:ss";

        local.fireDate=[NSDate dateWithTimeIntervalSinceNow:60];

        //滑动解锁的文字(在推送通知信息的下面一小行字)

        local.alertAction [email protected]" ";

        //有声音给声音,没声音用默认的

        [email protected]"UILocalNotificationDefaultSoundName";

        //设置图标右上角数字

        local.applicationIconBadgeNumber=1;

        //用户信息

        [email protected]{@"name":@"航海王",@"content":@"One Piece",@"time":@"20161201"};

        //3:定制一个通知 

        [[UIApplication sharedApplication]scheduleLocalNotification:local];

    }else{

        UNMutableNotificationContent* content = [[UNMutableNotificationContent alloc] init];

        content.title = [NSString localizedUserNotificationStringForKey:@"Hello Title" arguments:nil];

        content.body = [NSString localizedUserNotificationStringForKey:@"Hello Body" arguments:nil];

        content.sound = [UNNotificationSound defaultSound];

        //设定通知时间

        UNTimeIntervalNotificationTrigger* trigger = [UNTimeIntervalNotificationTrigger triggerWithTimeInterval:5 repeats:NO];

        UNNotificationRequest* request = [UNNotificationRequest requestWithIdentifier:@"notificationIdentifier" content:content trigger:trigger];

        UNUserNotificationCenter* center = [UNUserNotificationCenter currentNotificationCenter];

        [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {

        }];

    }

远程推送实现

　　服务器向客户端发送推送的过程:

　　　每个请求中都有设备令牌，APNs通过设备令牌去识别设备和APP,每次运行APP,都会向服务器发送设备令牌,服务器再使用设备令牌发送推送，只有当推送设置改变时设备令牌才会被改变 ,只有APNs 可以解码设备令牌.

　　服务器与APNS 连接过程:

头晕，这个还是看官方的文档:https://developer.apple.com/library/prerelease/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/APNSOverview.html#//apple_ref/doc/uid/TP40008194-CH8-SW1

信鸽 使用流程:

1、配置真机调试证书, 推送测试证书 (度娘·······)

2、注册iOS推送

 float sysVer = [[[UIDevice currentDevice] systemVersion] floatValue];
    if(sysVer < 8){
        [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];
    }else{
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= _IPHONE80_
        UIMutableUserNotificationCategory *categorys = [[UIMutableUserNotificationCategory alloc] init];
        UIUserNotificationSettings *userSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeBadge|UIUserNotificationTypeSound|UIUserNotificationTypeAlert
                                                                                     categories:[NSSet setWithObject:categorys]];
        [[UIApplication sharedApplication] registerUserNotificationSettings:userSettings];
        [[UIApplication sharedApplication] registerForRemoteNotifications];
#endif
    }

3、注册设备信息（deviceToken）

- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
   //注册设备
NSString * deviceTokenStr = [XGPush registerDevice: deviceToken];

   //打印获取的deviceToken的字符串
NSLog(@"deviceTokenStr is %@",deviceTokenStr);
}

3、注册信鸽

[XGPush startApp:@“10086” appKey:@"key"];

//设置账户[XGPush setAccount:@"123456"];//推送统计

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary*)userInfo

{

   [XGPush handleReceiveNotification:userInfo];

}
