Pod集成的EaseUI,我这里使用的是不带音视频的skd.(如果使用音视频版本请参考环信文档,但是后面具体操作基本一致)
打开cocoaPod(已安装的情况下,未安装的请自行百度安装) 然后cd到自己的项目工程下,
在pod中复制粘贴,(如果要指定版本，可以在更改后面的tag值,)
pod 'EaseUI', :git => 'https://github.com/easemob/easeui-ios-hyphenate-cocoapods.git', :tag => '3.3.6'
这里主要讲述单聊(自定义名片消息和正常的聊天消息)和聊天列表的集成实现.
一:单聊
自定义一个viewController 继承环信EaseUI中的EaseMessageViewController聊天界面控制器.我这边起名:CahtWithPVControllerViewController.我们主要实现单聊中的类似于淘宝和商家交谈发送某个商品的情况:正常消息和自定义消息的实现:如图
在我们继承好的自定义控制中,我们主要分清两种情况,自己发送和对方发送,自己接收和对方接收,这些我们都是可以根据代理实现的.所以我们要设置代理,然后实现代理.代码如下
继承代理<EaseMessageViewControllerDataSource,EaseMessageViewControllerDelegate>
- (void)viewDidLoad {
[super viewDidLoad];
self.showRefreshHeader = YES;
self.delegate= self;
self.dataSource = self;
}
实现原本的自有的方法
//会话界面的shua xin
- (void)tableViewDidTriggerHeaderRefresh
{
NSString*startMessageId =nil;
if ([self.messsagesSource count] > 0) {
startMessageId = [(EMMessage*)self.messsagesSource.firstObjectmessageId];
}
NSLog(@"startMessageID ------- %@",startMessageId);
[EMClient.sharedClient.chatManager asyncFetchHistoryMessagesFromServer:self.conversation.conversationId
conversationType:self.conversation.type
startMessageId:startMessageId
pageSize:10
completion:^(EMCursorResult*aResult,EMError*aError)
{
[super tableViewDidTriggerHeaderRefresh];
}];
}
先写到这里关键的代码在梳理完流程后在去写.
我在自定的CahtWithPVControllerViewController中为继承过来的tableView添加了一个头视图(根据项目需求来做,视图加在哪里都可以)就是下面这一块,
我的代码
- (void)configureGoodView {
UIView *bgV = [[UIView alloc] initWithFrame:CGRectMake(0, 10, kScreenWidth, 150)];
bgV.backgroundColor = [UIColor whiteColor];
UIImageView *imageV = [[UIImageView alloc] init];
imageV.frame=CGRectMake(15,15,80,80);
[imageVsd_setImageWithURL:[NSURL URLWithString:_goodImage] placeholderImage:[UIImage imageNamed:@"80"]];
[bgVaddSubview:imageV];
UILabel *titleLB = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMaxX(imageV.frame)+15, 15, kScreenWidth - CGRectGetWidth(imageV.frame) -30, 45)];
titleLB.font=kFont16;
titleLB.textColor=blackZiti;
titleLB.numberOfLines=0;
titleLB.text=_goodName;
[bgVaddSubview:titleLB];
UILabel *priceLB = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMaxX(imageV.frame)+15, CGRectGetMaxY(imageV.frame)- 30, kScreenWidth - CGRectGetWidth(imageV.frame) -30, 30)];
priceLB.font=kFont16;
priceLB.textColor = [UIColor redColor];
priceLB.text = [NSString stringWithFormat:@"¥%@",_goodPrice];
priceLB.numberOfLines=0;
[bgVaddSubview:priceLB];
UIButton *btn = [UIButton buttonWithType:(UIButtonTypeCustom)];
btn.frame=CGRectMake((kScreenWidth-100)/2,CGRectGetMaxY(imageV.frame)+15,100,30);
[btnsetTitle:@"发送宝贝" forState:(UIControlStateNormal)];
[btnsetTitleColor:erqiZiTColor forState:(UIControlStateNormal)];
btn.layer.masksToBounds = YES;
btn.titleLabel.font = kFont15;
btn.layer.cornerRadius = 35/2;
btn.layer.borderColor = erqiZiTColor.CGColor;
btn.layer.borderWidth = 0.8;
[btnaddTarget:self action:@selector(sendRecommendFriend) forControlEvents:(UIControlEventTouchUpInside)];
[bgVaddSubview:btn];
// [self tableViewDidTriggerHeaderRefresh];
self.tableView.tableFooterView = bgV;
}
在我们点击发送宝贝的时候要把这个宝贝发送给商家:类似于下图:
实现点击事件:
- (void)sendRecommendFriend{
[self sendTextMessage:@"商品链接" withExt:@{@"nickname":@"张三自己的名字",@"headimgurl":@"http://iamgename自己的头像",@"goodName":@"商品名字",@"goodPrice":@"商品价格",@"goodImage":@"商品图像",@"goodId":@"商品id"}];
//发送完成后把之前设置的tableFooterView置位空(根据需求来制定)
self.tableView.tableFooterView = nil;
}
这里我们用到EaseUI中的sendTextMessage这个方法,
- (void)sendTextMessage:(NSString*)text withExt:(NSDictionary*)ext;
第一个text是文本消息,这里我们用来作一个和其他消息区分的唯一标识,ext可以理解为消息体,是一个字典,用来存储想要发送的内容参数.在发送和接收端,我们可以根据text去找到ext,再根据自定义的消息cell去显示,具体如下
我们看到这条消息跟正常的聊天消息不一样,所以我们需要自定义一套cell来实现这些参数的显示:EaseUI本身有一套cell我们需要继承他们的cell以至于达到我们想要的目的.所以我们自定义一个继承EaseBaseMessageCell的cell 取名:IMChatBusinessCardCell,然后还需要针对EaseBubbleView写个分类，关联一些名片所需要的控件:取名IMChatBusinessCard .( commend+n选择Objective-C File如下图)
这些完成以后开始写代码,因为在自定义的聊天cell里我们需要显示商品图片,商品名字和商品价格.
所以我们在EaseBubbleView+IMChatBusinessCard.h中写
// 商品图片
@property(strong,nonatomic)UIImageView*userHeaderImageView;
// 商品名字
@property (strong, nonatomic) UILabel *userNameLabel;
// 商品价格
@property (strong, nonatomic) UILabel *userPhoneLabel;
// 设置名片气泡
- (void)setupBusinessCardBubbleView;
// 更新名片间距
- (void)updateBusinessCardMargin:(UIEdgeInsets)margin;
// 设置约束
- (void)_setupConstraintsXX;
然后在EaseBubbleView+IMChatBusinessCard.m中我这里全部复制一下,你们用的时候把重复的和没用的去掉就可以了.

[[UIImage imageNamed:imageName] stretchableImageWithLeftCapWidth:20 topCapHeight:35];
}
@end
然后我们回到自定义的聊天控制器CahtWithPVControllerViewController
导入刚才的类头文件
#import "IMChatBusinessCardCell.h"
#import "EaseBubbleView+IMChatBusinessCard.h"
我们需要实现- (UITableViewCell*)messageViewController:(UITableView*)tableView
cellForMessageModel:(id)messageModel;这个方法来显示我们自定义的cell
- (UITableViewCell*)messageViewController:(UITableView*)tableView
cellForMessageModel:(id)messageModel
{
if(messageModel.bodyType==EMMessageBodyTypeText&&
[[messageModeltext]hasPrefix:@"商品链接"]) {
NSString *CellIdentifier = [NSString stringWithFormat:@"%@", [NSDate dateTomorrow]];
IMChatBusinessCardCell*cell = (IMChatBusinessCardCell*)[tableViewdequeueReusableCellWithIdentifier:CellIdentifier];
if(cell ==nil) {
cell = [[IMChatBusinessCardCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier model:messageModel];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
cell.model= messageModel;
returncell;
}
return nil;
}
然后更改一下自定义消息的高度
- (CGFloat)messageViewController:(EaseMessageViewController*)viewController
heightForMessageModel:(id)messageModel
withCellWidth:(CGFloat)cellWidth
{
NSDictionary*ext = messageModel.message.ext;
if([extobjectForKey:@"em_recall"]) {
return self.timeCellHeight;
}
if([[messageModeltext]hasPrefix:@"商品链接"]) {
return130;
}
return 0;
}
为显示cell消息赋值的时候我们需要实现- (id)messageViewController:(EaseMessageViewController*)viewController modelForMessage:(EMMessage*)message;这个方法.
- (id)messageViewController:(EaseMessageViewController*)viewController modelForMessage:(EMMessage*)message
{
id model =nil;
model = [[EaseMessageModel alloc] initWithMessage:message];
if(model.isSender) {//自己发送
if([_typeChatisEqualToString:@"store"]) {
if(message.ext!=nil&& [[message.extallKeys]containsObject:@"goodName"]) {
model.message.ext =@{@"nickname":[SingleUserInfoManage shareData].nickname,@"headimgurl":[SingleUserInfoManage shareData].im_headimgurl,@"goodName":message.ext[@"goodName"],@"goodPrice":message.ext[@"goodPrice"],@"goodImage":message.ext[@"goodImage"],@"goodId":message.ext[@"goodId"]};
}else{
model.message.ext= @{@"headimgurl":[SingleUserInfoManage shareData].im_headimgurl,@"nickname":[SingleUserInfoManage shareData].nickname};
}
//头像
model.avatarURLPath = [SingleUserInfoManage shareData].im_headimgurl;
//昵称
model.nickname = [SingleUserInfoManage shareData].nickname;
//头像占位图
model.avatarImage = [UIImage imageNamed:@"默认头像2"];
}else{
if(message.ext!=nil&&[[message.extallKeys]containsObject:@"goodName"]) {
model.message.ext =@{@"nickname":[SingleUserInfoManage shareData].nickname,@"headimgurl":[SingleUserInfoManage shareData].im_headimgurl,@"goodName":message.ext[@"goodName"],@"goodPrice":message.ext[@"goodPrice"],@"goodImage":message.ext[@"goodImage"],@"goodId":message.ext[@"goodId"]};
}else{
model.message.ext= @{@"headimgurl":[SingleUserInfoManage shareData].im_headimgurl,@"nickname":[SingleUserInfoManage shareData].nickname};
}
//头像
model.avatarURLPath = [SingleUserInfoManage shareData].im_headimgurl;
//昵称
model.nickname = [SingleUserInfoManage shareData].nickname;
//头像占位图
model.avatarImage = [UIImage imageNamed:@"默认头像2"];
}
}else{//对方发送
//头像占位图
model.avatarImage = [UIImage imageNamed:@"默认头像2"];
//头像avatar
model.avatarURLPath= message.ext[@"headimgurl"];
//昵称
model.nickname= message.ext[@"nickname"];
}
returnmodel;
}
(附加)如果我们需要点击这个自定义消息,可以实现
我这里是跳转到商品详情:
//消息的点击
- (BOOL)messageViewController:(EaseMessageViewController*)viewController
didSelectMessageModel:(id)messageModel {
if(messageModel.bodyType==EMMessageBodyTypeText&&
[[messageModeltext]hasPrefix:@"商品链接"]) {
NSDictionary *ext = [[NSDictionary alloc]initWithDictionary:messageModel.message.ext];
FenLeiDDetailViewController *vc = [[FenLeiDDetailViewController alloc] init];
vc.goodsID= ext[@"goodId"];
[self.navigationController pushViewController:vc animated:YES];
}
return YES;
}
我们在这里面做很多判断主要用来区分正常消息和自定义消息,自定义消息(我们在发送消息的时候有一个text作为自定义消息的标识)由我们自定义的控件去完成.正常的消息由环信的控件去完成.这里面可能有一些我自己项目中用到你们用不到的东西,你们可以检查一下代码,修改成自己所需要的,有错误的调整一下.原理和代码大概就是这样.
最后附上demo，由于是从项目中抽取出来的，所以有点乱，但是还是能看的，哈哈，
