''EaseUI已不再维护，新用户建议集成新版UI库 'EaseIMKit'
文档地址：[[http://docs-im.easemob.com/im/ios/other/easeimkit|EaseIMKit集成]]''
===== 简介 =====
EaseUI 封装了 IM 功能常用的控件（如聊天会话、会话列表、联系人列表）。旨在帮助开发者快速集成环信 SDK。
源码地址：
* [[https://github.com/easemob/easeui_ios/tree/sdk3.x|EaseUI工程]]
* [[https://github.com/easemob/sdkdemoapp3.0_ios/tree/sdk3.x|Demo3.0工程]]
===== 视频教程 =====
以下是EaseUI集成参考视频，您可以通过视频学习如何集成环信SDK。
* [[https://ke.qq.com/webcourse/index.html#cid=320169&term_id=100380031&taid=2357924160922281&vid=z1428vxxdj0|OC_EaseUI集成]]
* [[https://ke.qq.com/webcourse/index.html#cid=320169&term_id=100380031&taid=2357932750856873&vid=o1428qrmocv|Swift_EaseUI集成]]
===== 快速集成 =====
=== 方法一: ===
pod 'EaseUI', :git => 'https://github.com/easemob/easeui-ios-hyphenate-cocoapods.git'
pod 'EaseUILite', :git =>'https://github.com/easemob/easeui-ios-hyphenate-cocoapods.git'
如果要指定版本，可以在后面添加tag，如
pod 'EaseUI', :git => 'https://github.com/easemob/easeui-ios-hyphenate-cocoapods.git', :tag => ‘3.3.4’
具体tag号和对应sdk版本号，可以从
https://github.com/easemob/easeui-ios-hyphenate-cocoapods/tags查看
**注意：**
EaseUI:对应Hyphenate SDK（sdk包含实时音视频）
EaseUILite:对应HyphenateLite SDK(sdk不包含实时音视频)
Pod集成EaseUI时，会同时通过Pod集成SDK
=== 方法二：===
* 集成 EaseUI 前，首先需要集成环信 iOS SDK，参考：集成文档
* 参考ChatDemo3.0 导入的方式,直接将EaseUI拖入已经集成SDK的项目中
**注意：**
* 添加的SDK要和EaseUI是同时下载的(目的是版本一致)。
* 如果使用Lite版本SDK，并用拖动的方式添加EaseUI, 需要在 ''Build Settings'' > ''GCC_PREPROCESSOR_DEFINITIONS'' 中添加 ''ENABLE_LITE=1'' (等号左右不能有空格)
**easeui中包含了拍照，发语音，发图片，发位置的功能，使用了录音，摄像头，相册，地理位置的权限。需要在您项目的info.plist中添加对应权限。**
===== 初始化 =====
第 1 步：引入相关头文件 #import "EaseUI.h"。
第 2 步：在工程的 AppDelegate 中的以下方法中，调用 EaseUI 对应方法。(注: 此方法不需要重复调用)
[[EaseSDKHelper shareHelper] hyphenateApplication:application
didFinishLaunchingWithOptions:launchOptions
appkey:appkey
apnsCertName:apnsCertName
otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
===== 聊天会话 =====
创建聊天会话、传递用户或群 ID 和会话类型（EMConversationType）。
EaseMessageViewController *chatController = [[EaseMessageViewController alloc] initWithConversationChatter:@"8001" conversationType:EMConversationTypeChat];
===== 聊天页面刷新 =====
EaseRefreshTableViewController提供了列表上拉加载、下拉刷新（加载）功能的UIViewController，其中已添加控件UITableView，默认未开启上拉加载、下来刷新（加载）的功能
==== 实现上拉加载功能 ====
继承自**EaseRefreshTableViewController**的子类，开启上拉加载需要设置showRefreshFooter为YES，并重写父类方法**- (void)tableViewDidTriggerFooterRefresh;**，如下：
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.showRefreshFooter = YES;
}
- (void)tableViewDidTriggerFooterRefresh {
//子类需要重写此方法
}
==== 实现下拉加载（刷新）功能 ====
继承自**EaseRefreshTableViewController**的子类，开启下拉加载（刷新）需要设置showRefreshHeader为YES，并重写父类方法**- (void)tableViewDidTriggerHeaderRefresh;**，如下：
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
self.showRefreshHeader = YES;
}
- (void)tableViewDidTriggerHeaderRefresh {
//子类需要重写此方法
}
===== 聊天会话功能扩展 =====
EaseUI 提供现成的聊天会话 ViewController，可以通过继承 EaseMessageViewController 方式（参考 ChatDemo-UI3.0 中 ChatViewController）实现对聊天会话的扩展。
也可以直接使用 EaseMessageViewController，通过 EaseMessageViewControllerDelegate 和 EaseMessageViewControllerDataSource 两个协议实现对 EaseMessageViewController 的扩展。
==== 实现自定义聊天样式 ====
EaseMessageViewControllerDelegate
获取自定义消息 cell，根据 messageModel，用户自己判断是否显示自定义消息 cell。如果返回 nil 会显示默认；如果返回 cell 会显示用户自定义消息cell。
/*!
@method
@brief 获取消息自定义cell
@discussion 用户根据messageModel判断是否显示自定义cell。返回nil显示默认cell，否则显示用户自定义cell
@param tableView 当前消息视图的tableView
@param messageModel 消息模型
@result 返回用户自定义cell
*/
- (UITableViewCell *)messageViewController:(UITableView *)tableView
cellForMessageModel:(id)messageModel;
/*!
@method
@brief 获取消息cell高度
@discussion 用户根据messageModel判断，是否自定义显示cell的高度
@param viewController 当前消息视图
@param messageModel 消息模型
@param cellWidth 视图宽度
@result 返回用户自定义cell
*/
- (CGFloat)messageViewController:(EaseMessageViewController *)viewController
heightForMessageModel:(id)messageModel
withCellWidth:(CGFloat)cellWidth;
//具体创建自定义Cell的样例：
- (UITableViewCell *)messageViewController:(UITableView *)tableView cellForMessageModel:(id)model
{
//样例为如果消息是文本消息显示用户自定义cell
if (model.bodyType == eMessageBodyType_Text) {
NSString *CellIdentifier = [CustomMessageCell cellIdentifierWithModel:model];
//CustomMessageCell为用户自定义cell,继承了EaseBaseMessageCell
CustomMessageCell *cell = (CustomMessageCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[CustomMessageCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier model:model];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
cell.model = model;
return cell;
}
return nil;
}
- (CGFloat)messageViewController:(EaseMessageViewController *)viewController
heightForMessageModel:(id)messageModel
withCellWidth:(CGFloat)cellWidth
{
//样例为如果消息是文本消息使用用户自定义cell的高度
if (messageModel.bodyType == EMMessageBodyTypeText) {
//CustomMessageCell为用户自定义cell,继承了EaseBaseMessageCell
return [CustomMessageCell cellHeightWithModel:messageModel];
}
return 0.f;
}
通过自定义cell展示动态表情的效果图：

- (void)messageViewController:(EaseMessageViewController *)viewController
didSelectAvatarMessageModel:(id)messageModel;
//获取用户点击头像回调的样例：
- (void)messageViewController:(EaseMessageViewController *)viewController
didSelectAvatarMessageModel:(id)messageModel
{

//样例的逻辑是选中消息头像后，进入该消息发送者的个人信息
UserProfileViewController *userprofile = [[UserProfileViewController alloc] initWithUsername:messageModel.message.from];
[self.navigationController pushViewController:userprofile animated:YES];
}

==== 聊天会话样式自定义 ====
聊天样式的自定义需要在 EaseMessageViewController 中 viewDidload 结束前设置。\\
@property中带有UI_APPEARANCE_SELECTOR，都可以通过set的形式设置样式，具体可以参考EaseBaseMessageCell.h,EaseMessageCell.h\\
=== 发送气泡图片设置 ===
[[EaseBaseMessageCell appearance] setSendBubbleBackgroundImage:[[UIImage imageNamed:@"chat_sender_bg"] stretchableImageWithLeftCapWidth:5 topCapHeight:35]];//设置发送气泡
[[EaseBaseMessageCell appearance] setRecvBubbleBackgroundImage:[[UIImage imageNamed:@"chat_receiver_bg"] stretchableImageWithLeftCapWidth:35 topCapHeight:35]];//设置接收气泡
=== 头像设置 ===
[[EaseBaseMessageCell appearance] setAvatarSize:40.f];//设置头像大小
[[EaseBaseMessageCell appearance] setAvatarCornerRadius:20.f];//设置头像圆角
=== 消息字体颜色设置 ===
[[EaseMessageCell appearance] setMessageTextFont:[UIFont systemFontOfSize:15]];//消息显示字体
[[EaseMessageCell appearance] setMessageTextColor:[UIColor blackColor]];//消息显示颜色
[[EaseMessageCell appearance] setMessageLocationFont:[UIFont systemFontOfSize:12]];//位置消息显示字体
[[EaseMessageCell appearance] setMessageLocationColor:[UIColor whiteColor]];//位置消息显示颜色
=== 语音消息图片样式设置 ===
[[EaseBaseMessageCell appearance] setSendMessageVoiceAnimationImages:@[[UIImage imageNamed:@"EaseUIResource.bundle/chat_sender_audio_playing_full"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_sender_audio_playing_000"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_sender_audio_playing_001"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_sender_audio_playing_002"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_sender_audio_playing_003"]]];//发送者语音消息播放图片
[[EaseBaseMessageCell appearance] setRecvMessageVoiceAnimationImages:@[[UIImage imageNamed:@"EaseUIResource.bundle/chat_receiver_audio_playing_full"],[UIImage imageNamed:@"EaseUIResource.bundle/chat_receiver_audio_playing000"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_receiver_audio_playing001"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_receiver_audio_playing002"], [UIImage imageNamed:@"EaseUIResource.bundle/chat_receiver_audio_playing003"]]];//接收者语音消息播放图片
==== 聊天会话输入框自定义 ====
继承EaseMessageViewController,或者EaseMessageViewController的实例调用以下方法设置底部输入框
CustomerInputView *inputView = [[CustomerInputView alloc] init];//CustomerInputView用户自定义底部输入框
[self setChatToolbar:inputView];
实现默认底部输入框delegate
@interface CustomerInputView : UIView
@property (weak, nonatomic) id delegate;
@end
=== 自定义输入框发送消息 ===
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text{
if ([text isEqualToString:@"\n"]){
if(self.delegate && [self.delegate respondsToSelector:@selector(didSendText:)]) {
[self.delegate didSendText:self.textView.text];
}
self.textView.text = @"";
self.placeholderLabel.text = @"说点什么吧...";
return NO;
}
return YES;
}
=== 自定义输入框高度变化 ===
//这是一个举例,初始化输入框的时候注册监听键盘高度变化
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:)name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:)name:UIKeyboardWillHideNotification object:nil];
- (void)keyboardWillShow:(NSNotification *)aNotification{
//获取键盘的高度
NSValue *aValue = [[aNotification userInfo] objectForKey:UIKeyboardFrameEndUserInfoKey];
CGRect keyboardRect = [aValue CGRectValue];
if (keyboardRect.size.height > self.keyboardHeight) {
self.keyboardHeight = keyboardRect.size.height;
}
self.frame = CGRectMake(0, _originY - self.keyboardHeight - 64, App_Width, self.inputH + self.keyboardHeight);
if (self.delegate && [self.delegate respondsToSelector:@selector(chatToolbarDidChangeFrameToHeight:)]) {
[self.delegate chatToolbarDidChangeFrameToHeight:self.frame.size.height];
}
}
- (void)keyboardWillHide:(NSNotification *)aNotification{
self.frame = CGRectMake(0, _originY - 64, App_Width, self.inputH) ;
if (self.delegate && [self.delegate respondsToSelector:@selector(chatToolbarDidChangeFrameToHeight:)]) {
[self.delegate chatToolbarDidChangeFrameToHeight:self.frame.size.height];
}
}
==== 聊天会话底部菜单自定义 ====
**EaseChatBarMoreView**为自定义的功能菜单选择视图，目前已添加的功能有：\\
/*!
@method
@brief 新增一个新的功能按钮
@discussion
@param image 按钮图片
@param highLightedImage 高亮图片
@param title 按钮标题
@result
*/
- (void)insertItemWithImage:(UIImage*)image
highlightedImage:(UIImage*)highLightedImage
title:(NSString*)title;
/*!
@method
@brief 修改功能按钮图片
@discussion
@param image 按钮图片
@param highLightedImage 高亮图片
@param title 按钮标题
@param index 按钮索引
@result
*/
- (void)updateItemWithImage:(UIImage*)image
highlightedImage:(UIImage*)highLightedImage
title:(NSString*)title
atIndex:(NSInteger)index;
/*!
@method
@brief 根据索引删除功能按钮
@discussion
@param index 按钮索引
@result
*/
- (void)removeItematIndex:(NSInteger)index;
各个选项的功能需要ViewController实现EaseChatBarMoreViewDelegate协议中的回调方法来编写或调整.
===== 消息发送 =====
EaseSDKHelper 封装了发送消息的方法。
具体发送消息样例：
/*
EMChatTypeChat 单聊消息
EMChatTypeGroupChat 群聊消息
EMChatTypeChatRoom 聊天室消息
*/
//发送文字消息
EMMessage *message = [EaseSDKHelper sendTextMessage:@"要发送的消息"
to:@"6001"//接收方
messageType:EMChatTypeChat//消息类型
messageExt:nil]; //扩展信息
//发送位置消息
EMMessage *message = [EaseSDKHelper sendLocationMessageWithLatitude:35.1//经度
longitude:35.1//纬度
address:"地址"
to:@"6001"//接收方
messageType:EMChatTypeChat//消息类型
messageExt:nil];//扩展信息
//发送图片消息
EMMessage *message = [EaseSDKHelper sendImageMessageWithImageData:imageData//发送的图片数据NSData
to:@"6001"//接收方
messageType:EMChatTypeChat//消息类型
messageExt:nil];//扩展信息
//发送音频消息
EMMessage *message = [EaseSDKHelper sendVoiceMessageWithLocalPath:localPath//音频本地地址
duration:duration//语音的时长，单位是秒
to:@"6001"//接收方
messageType:EMChatTypeChat//消息类型
messageExt:nil];//扩展信息
//发送视频文件消息
EMMessage *message = [EaseSDKHelper sendVideoMessageWithURL:url//发送的视频地址
to:@"6001"//接收方
messageType:EMChatTypeChat//消息类型

===== EaseUI中使用的第三方库 =====
* MBProgressHUD
* MJRefresh
* MWPhotoBrowser
* SDWebImage
* DACircularProgressView
==== EaseUI中第三方库冲突问题 ====
目前推荐Pod的方式集成EaseUI。如果集成了EaseUI，而且上述第三方依赖在开发者的代码中也有引用，会造成冲突，无法编译，针对此问题有如下两种场景：
* 开发者使用的第三方依赖也是通过pod方式集成，这样pod只会安装一份，不会重复安装多个版本。如果是依赖版本不兼容，例如开发者依赖了'''MBProgressHUD', '~> 1.0.0' ''，而EaseUI通过MWPhotoBrowser间接依赖了'''MBProgressHUD', '~> 0.9' ''，这样会导致pod install失败，开发者可以改变''MBProgressHUD''的依赖版本。EaseUI也会在后续版本中尽量减少使用第三方依赖。
* 如果是手动导入了上述第三方库，建议直接删除手动导入的部分，避免冲突的产生，如果EaseUI使用第三方库的版本不能满足开发者的需求，开发者也可以手动将第三方库进行重命名，保证兼容（手动方式集成EaseUI也可以参考此解决方案）。
