解决环信聊天头像跟昵称的问题

1.首先环信聊天是不支持头像跟昵称管理的,所以要想办法把昵称跟头像放在自己的服务器上来管理

- (void)_sendMessage:(EMMessage *)message
{   
    NSMutableDictionary *dict =  [NSMutableDictionary dictionaryWithDictionary:message.ext];
    NSDictionary *userData = [XQUserData getUserData];
    [dict setValue:userData[@"nickName"] forKey:@"userName"];
    [dict setValue:userData[@"headImg"] forKey:@"userPic”];
}
在下面这个方法中获取解析头像
- (id)messageViewController:(EaseMessageViewController *)viewController
                           modelForMessage:(EMMessage *)message
{
    id model = nil;
    model = [[EaseMessageModel alloc] initWithMessage:message];
    if (model.message.ext) {
        model.avatarURLPath = model.message.ext[@"userPic"];
        //昵称
        model.nickname = model.message.ext[@"userName"];
        //头像占位图
        model.failImageName = @"imageDownloadFail";
    }else{
       model.avatarImage = [UIImage imageNamed:@"EaseUIResource.bundle/user"];
        //头像占位图
        model.failImageName = @"imageDownloadFail";
    }

    return model;
}

只需要更改两处就可以解决了,只需要跟搞安卓协商好这两个Key就可以很好的完成安卓跟iOS互相聊天是显示昵称跟头像了.
