今天 花了一天的时间终于将推送给弄好了，才发现其实很简单，就是因为自己的几个方法木有实现才导致花了那么多的冤枉时间

推送的步骤如下

1.先创建一个apns推送证书，请参照：http://developer.easemob.com/docs/emchat/ios/push/certificate.html

创建证书后将apns证书打包成p12文件，然后上传到环信的后台

2.在创建开发者证书和描述文件，这个证书跟上面的apns证书是不同的，这个证书是用来真机调试的，appid要有推送功能

3.将环信的appkey和证书写入工程中，代码如下

//注册 APNS文件的名字, 需要与后台上传证书时的名字一一对应

NSString *apnsCertName = @"125642";

[[EaseMob sharedInstance] registerSDKWithAppKey:@“4dasfdas” apnsCertName:apnsCertName];

[[EaseMob sharedInstance] enableBackgroundReceiveMessage];

[[EaseMob sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];

4.实现收到消息的几个回调方法就可以了

// 收到消息回调

-(void)didReceiveMessage:(EMMessage *)message{

#if !TARGET_IPHONE_SIMULATOR

    [self playSoundAndVibration];

    BOOL isAppActivity = [[UIApplication sharedApplication] applicationState] == UIApplicationStateActive;

    if (!isAppActivity) {

        [self showNotificationWithMessage:message];

    }

#endif

}

- (void)playSoundAndVibration{

    //如果距离上次响铃和震动时间太短, 则跳过响铃

    NSLog(@"%@, %@", [NSDate date], self.lastPlaySoundDate);

    NSTimeInterval timeInterval = [[NSDate date]

                                   timeIntervalSinceDate:self.lastPlaySoundDate];

    if (timeInterval < kDefaultPlaySoundInterval) {

        return;

    }

    //保存最后一次响铃时间

    self.lastPlaySoundDate = [NSDate date];

    // 收到消息时，播放音频

    [[EaseMob sharedInstance].deviceManager asyncPlayNewMessageSound];

    // 收到消息时，震动

    [[EaseMob sharedInstance].deviceManager asyncPlayVibration];

}

- (void)showNotificationWithMessage:(EMMessage *)message

{

    EMPushNotificationOptions *options = [[EaseMob sharedInstance].chatManager pushNotificationOptions];

    //发送本地推送

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

    notification.fireDate = [NSDate date]; //触发通知的时间

    if (options.displayStyle == ePushNotificationDisplayStyle_messageSummary) {

        id messageBody = [message.messageBodies firstObject];

        NSString *messageStr = nil;

        switch (messageBody.messageBodyType) {

            case eMessageBodyType_Text:

            {

                messageStr = ((EMTextMessageBody *)messageBody).text;

            }

                break;

            case eMessageBodyType_Image:

            {

                messageStr = @"[图片]";

            }

                break;

            case eMessageBodyType_Location:

            {

                messageStr = @"[位置]";

            }

                break;

            case eMessageBodyType_Voice:

            {

                messageStr = @"[音频]";

            }

                break;

            case eMessageBodyType_Video:{

                messageStr = @"[视频]";

            }

                break;

            default:

                break;

        }

        NSString *title = message.from;

        if (message.isGroup) {

            NSArray *groupArray = [[EaseMob sharedInstance].chatManager groupList];

            for (EMGroup *group in groupArray) {

                if ([group.groupId isEqualToString:message.conversation.chatter]) {

                    title = [NSString stringWithFormat:@"%@(%@)", message.groupSenderName, group.groupSubject];

                    break;

                }

            }

        }

        notification.alertBody = [NSString stringWithFormat:@"%@:%@", title, messageStr];

    }

    else{

        notification.alertBody = @"您有一条新消息";

    }

#warning 去掉注释会显示[本地]开头, 方便在开发中区分是否为本地推送

    //notification.alertBody = [[NSString alloc] initWithFormat:@"[本地]%@", notification.alertBody];

    notification.alertAction = @"打开";

    notification.timeZone = [NSTimeZone defaultTimeZone];

    //发送通知

    [[UIApplication sharedApplication] scheduleLocalNotification:notification];

    UIApplication *application = [UIApplication sharedApplication];

    application.applicationIconBadgeNumber += 1;

}
