1.先建立一個apns證書，連接以下ios

　　http://developer.easemob.com/docs/emchat/ios/push/certificate.htmlapp

　　建立完證書後，將證書弄成p12文件，而後上傳到環信後臺async

2.再建立真機調試證書，和描述文件，保證能進行真機調試。而且appid要又推送功能ide

3.綁定環信證書和appkeyatom

//註冊 APNS文件的名字, 須要與後臺上傳證書時的名字一一對應
NSString *apnsCertName = @"chatdemo";
[[EaseMob sharedInstance] registerSDKWithAppKey:@「4545521」 apnsCertName:apnsCertName];
[[EaseMob sharedInstance] enableBackgroundReceiveMessage];
[[EaseMob sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];

4.而後實現環信的幾個方法

// 收到消息回調
-(void)didReceiveMessage:(EMMessage *)message{
    
#if !TARGET_IPHONE_SIMULATOR
    [self playSoundAndVibration];
    
    BOOL isAppActivity = [[UIApplication sharedApplication] applicationState] == UIApplicationStateActive;
    if (!isAppActivity) {
        [self showNotificationWithMessage:message];
    }
#endif
}

- (void)playSoundAndVibration{
    
    //若是距離上次響鈴和震動時間過短, 則跳過響鈴
    NSLog(@"%@, %@", [NSDate date], self.lastPlaySoundDate);
    NSTimeInterval timeInterval = [[NSDate date]
                                   timeIntervalSinceDate:self.lastPlaySoundDate];
    if (timeInterval < kDefaultPlaySoundInterval) {
        return;
    }
    //保存最後一次響鈴時間
    self.lastPlaySoundDate = [NSDate date];
    
    // 收到消息時，播放音頻
    [[EaseMob sharedInstance].deviceManager asyncPlayNewMessageSound];
    // 收到消息時，震動
    [[EaseMob sharedInstance].deviceManager asyncPlayVibration];
}

- (void)showNotificationWithMessage:(EMMessage *)message{
    id<IEMMessageBody> messageBody = [message.messageBodies firstObject];
    NSString *messageStr = nil;
    switch (messageBody.messageBodyType) {
        case eMessageBodyType_Text:
        {
            messageStr = ((EMTextMessageBody *)messageBody).text;
        }
            break;
        case eMessageBodyType_Image:
        {
            messageStr = @"[圖片]";
        }
            break;
        case eMessageBodyType_Location:
        {
            messageStr = @"[位置]";
        }
            break;
        case eMessageBodyType_Voice:
        {
            messageStr = @"[音頻]";
        }
            break;
        case eMessageBodyType_Video:{
            messageStr = @"[視頻]";
        }
            break;
        default:
            break;
    }
    
    //發送本地推送
    UILocalNotification *notification = [[UILocalNotification alloc] init];
    notification.fireDate = [NSDate date]; //觸發通知的時間
    
    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];
    notification.alertAction = @"打開";
    notification.timeZone = [NSTimeZone defaultTimeZone];
    notification.soundName = UILocalNotificationDefaultSoundName;

    //發送通知
    [[UIApplication sharedApplication] scheduleLocalNotification:notification];
    UIApplication *application = [UIApplication sharedApplication];
    application.applicationIconBadgeNumber += 1;
}

這樣就能夠進行消息推送了

通過本身的研究，我的拓展一下：通常接收消息推送通知放在主控制器去操做，只須要在主控制器註冊代理，便可回調，發送通知spa

//**************************************************遠程通知部分*******************************************************//

//兩次提示的默認間隔.net

#import "MainViewController.h"代理

static const CGFloat kDefaultPlaySoundInterval = 3.0; 調試

static NSString *kMessageType = @"MessageType";

static NSString *kConversationChatter = @"ConversationChatter";

@interface MainViewController ()<EMChatManagerChatDelegate>

@property (strong, nonatomic) NSDate *lastPlaySoundDate;

@end

#pragma - 遠程通知部分

{
    BOOL ret = YES;
    NSArray *igGroupIds = [[EaseMob sharedInstance].chatManager ignoredGroupIds];
    for (NSString *str in igGroupIds) {
        if ([str isEqualToString:fromChatter]) {
            ret = NO;
            break;
        }
    }
    return ret;
}

// 收到消息回調

        UIApplicationState state = [[UIApplication sharedApplication] applicationState];
        switch (state) {
            case UIApplicationStateActive:
                [self playSoundAndVibration];
                break;
