前期准备工作：到苹果开发者网站上注册AppID、推送证书、描述性证书

代码段实现：

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)]) {        //IOS8        //创建UIUserNotificationSettings，并设置消息的显示类类型        UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIUserNotificationTypeSound) categories:nil];                [application registerUserNotificationSettings:notiSettings];    }else{               //ios7.0及以下        [application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge                                       |UIRemoteNotificationTypeSound    |UIRemoteNotificationTypeAlert)];        }

代理方法实现

//会接收来自苹果服务器给你返回的deviceToken，然后你需要将它添加到你本地的推送服务器上。（很重要，决定你的设备能不能接收到推送消息）。- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)pToken{    //注册成功，将deviceToken保存到应用服务器数据库中，在应用服务器端需要    NSLog(@"---Token--%@", pToken);   }//当注册失败时，触发此函数- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error{        NSLog(@"Regist fail%@",error);}//- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{    //处理推送消息    NSLog(@"userInfo == %@",userInfo);    NSString *message = [[userInfo objectForKey:@"aps"]objectForKey:@"alert"];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示" message:message delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定",nil];        [alert show];}

2.PHP服务端

将simplepush.php这个推送脚本也放在push文件夹中

      $message,      'sound' => 'default'      );            // Encode the payload as JSON      $payload = json_encode($body);            // Build the binary notification      $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;            // Send it to the server      $result = fwrite($fp, $msg, strlen($msg));            if (!$result)      echo 'Message not delivered' . PHP_EOL;      else      echo 'Message successfully delivered' . PHP_EOL;            // Close the connection to the server      fclose($fp);      ?>

deviceToken填写你接收到的token,passPhrase则填写你的ck.pem设置的密码。

此刻就是见证奇迹的时候了

使用终端进入到push文件夹，在终端输入 php simplepush.php

若显示以上提示则表示推送成功了。
