iOS不使用第三方平台，发送推送消息

先看看客户端：

需要关注两个点：一是代码部分的DeviceToken获取，且看代码

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions

{

//消息推送支持的类型

UIRemoteNotificationTypetypes =

(UIRemoteNotificationTypeBadge

|UIRemoteNotificationTypeSound

|UIRemoteNotificationTypeAlert);

//注册消息推送

[[UIApplicationsharedApplication]registerForRemoteNotificationTypes:types];

// Override point for customization after application launch.

returnYES;

}

//获取DeviceToken成功

- (void)application:(UIApplication*)application

didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken

{

NSString*pushToken = [[[[deviceTokendescription]

stringByReplacingOccurrencesOfString:@"<"withString:@""]

stringByReplacingOccurrencesOfString:@">"withString:@""]

stringByReplacingOccurrencesOfString:@" "withString:@""] ;

NSLog(@"DeviceToken:%@",pushToken);

//这里进行的操作，是将Device Token发送到服务端

}

注：这里用到一个小技巧，怎样把NSData数据内容里面的“<”,">"," "给去掉，得到一个有效的DeviceToken。

//注册消息推送失败

- (void)application:(UIApplication*)application

didFailToRegisterForRemoteNotificationsWithError:(NSError*)error

{

NSLog(@"Register Remote Notifications error:{%@}",[errorlocalizedDescription]);

}

//处理收到的消息推送

- (void)application:(UIApplication*)application

didReceiveRemoteNotification:(NSDictionary*)userInfo

{

NSLog(@"Receive remote notification : %@",userInfo);

NSDictionary*aps = [userInfovalueForKey:@"aps"];

NSString*content = [apsvalueForKey:@"alert"];//推送显示的内容

UIAlertView*alert =

[[UIAlertViewalloc]initWithTitle:@"温馨提示"

message:content

delegate:nil

cancelButtonTitle:@"确定"

otherButtonTitles:nil];

[alertshow];

}

二是制作带有推送消息的证书

进入苹果开发网站：

选中带有推送服务：

创建成功之后，下载证书双击，在钥匙串就能看到：

右键导出p12文件，可以设置密码，也可以不设，一般不设置。以上证书就OK了。

下面来看看java写的服务器代码：

package com.sdunicom.iphone.apns;

import javapns.back.PushNotificationManager;
import javapns.back.SSLConnectionHelper;
import javapns.data.Device;
import javapns.data.PayLoad;

public class MainSend {
public static void main(String[] args) throws Exception {
try {
String deviceToken = "56378f94d620b0210a9228ea513a4ba2cbe61d0b29143116812da411009c0c9e";

PayLoad payLoad = new PayLoad();
payLoad.addAlert("盛科维的同胞们，大家好");
payLoad.addBadge(1);//消息推送标记数，小红圈中显示的数字。
payLoad.addSound("default");

PushNotificationManager pushManager = PushNotificationManager.getInstance();
pushManager.addDevice("iPhone", deviceToken);

//Connect to APNs
String host= "gateway.sandbox.push.apple.com";
int port = 2195;
String certificatePath= "/Users/wangjinhan/Desktop/最近技术研究/java后台推送程序/developcm.p12";
String certificatePassword= "";
pushManager.initializeConnection(host,port, certificatePath,certificatePassword, SSLConnectionHelper.KEYSTORE_TYPE_PKCS12);

//Send Push
Device client = pushManager.getDevice("iPhone");
pushManager.sendNotification(client, payLoad);
pushManager.stopConnection();

pushManager.removeDevice("iPhone");
}
catch (Exception e) {
e.printStackTrace();
}

}
}

/***********************

代码有几点要注意：

1.String deviceToken = "56378f94d620b0210a9228ea513a4ba2cbe61d0b29143116812da411009c0c9e";

要发送到对应的设备

2.payLoad.addBadge(1);

消息推送标记数，小红圈中显示的数字。服务器上作一个累计，当点击就计数为了，如果没有查看就一直累加。

3.String certificatePath= "/Users/wangjinhan/Desktop/最近技术研究/java后台推送程序/developcm.p12";

证书的路径，不能出错

4.String certificatePassword= "";

导出证书设置的密码，没有设置密码，就如上
