#EaseMobDIYUI @(EaseMob)[自定义聊天UI|简单继承|pod]
- LeanCloud:LeanCloud 实时消息只需几行代码,就可使用户的应用完成移动 IM 的功能添加。 IM 系统与当前用户系统完全解耦,无需同步或修改现有用户体系,即可使用;除 iOS、Android 移动开发的原生 SDK 之外,还也支持网页内聊天。
- 融云:融云是国内首家专业的即时通讯云服务提供商,专注为互联网、移动互联网开发者提供即时通讯基础能力和云端服务。通过融云平台,开发者不必搭建服务端硬件环境,就可以将即时通讯、实时网络能力快速集成至应用中 针对开发者所需的不同场景,融云平台提供了一系列产品、技术解决方案,包括:客户端 IM组件,客户端 IM 基础库,服务端 RESTAPI,客户端实时网络通讯基础库等。利用这些解决方案,开发者可以直接在自己的应用中构建出即时通讯产品,也可以无限创意出自己的即时通讯场景。 融云 SDK 包括两部分:IM 界面组件和 IM 能力库。
- 环信:环信即时通讯云是移动即时通讯能力的云计算 PaaS (Platform as a Service, 平台即服务)平台服务商。移动即时通讯能力是指基于互联网和移动终端的单聊,群聊,富媒体消息,实时语音,实时视频,多人语音视频,流媒体播放及互动等通讯能力。环信将移动即时通讯能力通过云端开放的API 和客户端 SDK 包的方式提供给开发者和企业,帮助合作伙伴在自己的产品中便捷、快速的实现通讯和社交功能
- EaseMobDIYUI:LeanCloud、融云、环信是我用过IM平台,也是当前比较受欢迎的三个IM平台。通过对比它们的优缺点,还是非常明显的。LeanCloud免费内容太少,超过500用户就要收费,SDK支持的平台倒是挺多的。融云还不错,在1.0时代有太多的问题,有幸看到过它们的UI代码,写的比较烂。没有WinPhone的支持, Server SDK支持也比较多。环信在免费内容上和融云做得差不多,SDK 的API也不错,但是没有让开发者直接拿来继承使用的UI(只是有个Demo,但是直接使用太麻烦,如果能pod得话就更好,这也是我现在写这个项目的初衷)。
集成环信的即时通讯功能,pod集成,方便管理。简单继承,轻松定制自己的UI界面。当前最新版本```0.2.6```,主要由会话列表(```EM_ConversationListController```)、好友列表(```EM_FriendsController```)和聊天界面(```EM_ChatController```)组成。很多功能和界面都在开发中,聊天界面的UI也没有开发完善,所以现在显示很挫。在```1.0.0```版本之前会完成所有可以使用环信SDK实现的功能,并且加入其它实用的功能,在此之前也不适合使用。当然你也可以参考环信的[Demo](http://www.easemob.com/downloads)。 使用pod集成的[EaseMobSDKFull](https://github.com/easemob/sdk-ios-cocoapods-integration),集成版本```2.2.0```。因为pod集成[EaseMobSDK](https://github.com/easemob/sdk-ios-cocoapods/tree/master/EaseMobSDK)是没有语音和视频通讯功能的。根据环信的官方文档来看,pod集成的是私有库,cocoapods公共库上的SDK已经弃用了。所以需要大家自己单独pod环信SDK - 会话编辑状态保存 - 最近Emoji表情的保存 - 自定义扩展View,由环信的消息扩展来决定 - 语音消息发送之前的播放 - 自定义Action,除了图片、相机、语音、视频、位置和文件等Action外,可以额外添加其它Action,View会根据数量来自动增加翻页 - 语音识别(未实现) - 文件浏览器 - WiFi文件上传 - ....... iOS版本7.0以上 ``` pod 'EaseMobSDKFull',:git => 'https://github.com/easemob/sdk-ios-cocoapods-integration.git' ``` ``` pod 'EaseMobDIYUI', :git => 'https://github.com/AwakenDragon/EaseMobDIYUI.git' ``` ``` pod 'VoiceConvert',:git => "https://github.com/AwakenDragon/VoiceConvert.git" ```
PS:语音消息的播放需要VoiceConvert功能模块,开始我试图直接把VoiceConvert功能代码放到项目里使用,但在制作成pod并使用的时候,总是报找不到相关类库文件的错误。无奈只能单独将VoiceConvert功能做成pod来集成。但在制作EaseMobDIYUI的pod的时候,没有办法把VoiceConvert作为依赖添加进入,所以只能要求使用者,在pod EaseMobDIYUI 的时候,同时pod VoiceConvert。后期,我会想办法修复这个问题,好可以只pod EaseMobDIYUI。
在pod [EaseMobDIYUI](https://github.com/AwakenDragon/EaseMobDIYUI)的时候,EaseMobUI已经添加了以下依赖: - ```'SDWebImage', '3.7.3'``` 用来加载图片的 [SDWebImage](https://github.com/rs/SDWebImage) - ```'MJRefresh', '2.4.7'``` 上拉下拉,相信你也会用到 [MJRefresh](https://github.com/CoderMJLee/MJRefresh) - ```'MWPhotoBrowser', '2.1.1'``` 图片浏览,同时也支持视频播放 [MWPhotoBrowser](https://github.com/mwaterfall/MWPhotoBrowser) - ```'MBProgressHUD', '0.9.1'``` 主要还是toast功能 [MBProgressHUD](https://github.com/jdg/MBProgressHUD) - ```'TTTAttributedLabel', '1.13.4'``` 富文本显示 [TTTAttributedLabel](https://github.com/TTTAttributedLabel/TTTAttributedLabel) - ```'SWTableViewCell','0.3.7'``` Cell左滑显示自定按钮 [SWTableViewCell](https://github.com/CEWendel/SWTableViewCell) - ```'FXBlurView','1.6.3'``` 毛玻璃效果 [FXBlurView](https://github.com/nicklockwood/FXBlurView) - ```'JSONModel','1.1.0'``` JSON数据解析 [JSONModel](https://github.com/icanzilb/JSONModel) - ```'pop','1.0.7'``` View动画 [pop](https://github.com/facebook/pop) - ```GPUImage``` 图片及视频处理,pod运行的时候报错,暂时直接将代码放到了项目里 [GPUImage](https://github.com/BradLarson/GPUImage) - ```CocoaHTTPServer``` 用来实现WiFi文件上传,pod无效 [CocoaHTTPServer](https://github.com/robbiehanson/CocoaHTTPServer) - ```Emoji``` Emoji表情,无法pod [Emoji](https://github.com/limejelly/Emoji) 所以你不需要再额外pod这些了。后期我会对依赖做适当的增加或删除。**注意事项1:*在pod完成开始运行的时候, EaseMobSDKFull
的一个文件EMErrorDefs.h
*可能会报错,具体原因是几个枚举没有或者重复。
**解决办法:**从环信最新的SDK(EaseMobSDK )中拿到这个文件,然后进入自己项目EaseMobSDKFull的对应pod目录,覆盖掉该文件即可。虽然在XCode
里不允许修改pod的文件,但这样做事没有问题的。
**注意事项2:**当前Git上的项目其实就是一个Demo
,然后把其中一部分作为pod
。相信你在看podspec文件的时候就能够看出来,当你clone
本项目的时候,也需要pod install
命令来集成一些必要的组件。如果你直接运行pod install
命令是不行的,直接报错。因为项目的Podfile
文件中有的组件是通过本地路径来pod
的,我也是通过这种方式来测试pod
的。
**解决办法:**将本地pod
路径修改为对应的网络路径便可。例如pod 'EaseMobSDKFull', :git => '/Users/ZhouYuzhen/Documents/Git/IOS/EaseMobSDKFull'
改为pod 'EaseMobSDKFull',:git => 'https://github.com/easemob/sdk-ios-cocoapods-integration.git'
即可。项目所用到的所有第三方组件都会在文档中有跳转链接。不过我的建议是,最好把一些大的组件clone
到本地,然后进行本地pod
,这样速度会很快。

<h4 id = "2.4.2">权限</h4>
为了功能的正常时候,我们需要以下权限
- **位置** *在Info.plist中添加NSLocationAlwaysUsageDescription(始终允许使用)、NSLocationWhenInUseUsageDescription(使用期间允许使用)*
- **照片**
- **麦克风**
- **相机**
- **通知** *注册APNS*
- **后台应用程序刷新** *在Info.plist中添加Required background modes 并添加App plays audio or streams audio/video using AirPlay、App downloads content in response to push notifications和App provides Voice over IP services三项;或者在Capabilities中打开Background Models,勾选Audio and Airplay、Voice over IP和Remote notifications*
- **使用蜂窝移动数据**
- **iOS9下的网络访问** *iOS9引入了新特性```App Transport Security (ATS)```,新特性要求App内访问的网络必须使用```HTTPS```协议。所以可能会导致网络访问不通,在```Info.plist```中添加```NSAppTransportSecurity类型Dictionary```,
并在```NSAppTransportSecurity```下添加```NSAllowsArbitraryLoads类型Boolean```,值设为```YES```,便可。*

<h3 id = "2.8">自定义扩展</h3>
**自定义扩展**是通过环信```EMMessage```的扩展属性```ext```来实现的,我只是对自定义扩展进行了规范,可以让大家方便扩展的同时实现了自己的一些功能。为了统一iOS和Android,在声明属性的时候请尽量只声明NSString、BOOL和数字类型,因为Android只支持这些类型。
EM_ChatMessageExtendBody
所有的自定义扩展必须继承```EM_ChatMessageExtendBody```,且必须重写```+ (NSString *)identifierForExtend```、```+ (Class)viewForClass```、```+ (BOOL)showBody```和```+ (BOOL)showExtend```方法。同时在初始化```EaseMobUIClient```的时候注册自定义消息,```[[EaseMobUIClient sharedInstance] registerExtendClass:[UserCustomExtend class]];```。
发送自定义扩展消息,在聊天界面中调用```- (void)sendMessage:(EM_ChatMessageModel *)message```方法。
UserCustomExtend *custom = [[UserCustomExtend alloc]init]; EM_ChatMessageModel *customMessage = [EM_ChatMessageModel fromText:@"" conversation:self.conversation]; customMessage.messageExtend.extendBody = custom; [self sendMessage:customMessage];
#import "JSONModel.h"
#define kIdentifierForExtend (@"kIdentifierForExtend")
@interface EM_ChatMessageExtendBody : JSONModel
/**
- 扩展标示,iOS和Android两个平台必须一致
- @return */
- (NSString *)identifierForExtend;
/**
- 扩展对应的显示View
- @return */
- (Class)viewForClass;
/**
- 是否显示消息体
- @return */
- (BOOL)showBody;
/**
- 是否显示扩展体
- @return */
- (BOOL)showExtend;
@end
扩展绑定的```View```必须继承自```EM_ChatMessageExtendView```,同时必须重写```+ (CGSize)sizeForContentWithMessage:(EM_ChatMessageModel *)message maxWidth:(CGFloat)maxWidth config:(EM_ChatMessageUIConfig *)config```方法。
#import "EM+ChatMessageExtendView.h"
@interface UserCustomExtendView : EM_ChatMessageExtendView
@end
#import "UserCustomExtendView.h" #import "EM+ChatMessageModel.h" #import "UserCustomExtend.h"
@implementation UserCustomExtendView{ UILabel *label; }
- (CGSize)sizeForContentWithMessage:(EM_ChatMessageModel *)message maxWidth:(CGFloat)maxWidth config:(EM_ChatMessageUIConfig *)config{ return CGSizeMake(80, 30); }
-
(instancetype)init{ self = [super init]; if (self) { label = [[UILabel alloc]init]; label.textColor = [UIColor blackColor]; [self addSubview:label]; } return self; }
-
(void)layoutSubviews{ [super layoutSubviews]; label.frame = self.bounds; }
-
(void)setMessage:(EM_ChatMessageModel *)message{ [super setMessage:message]; UserCustomExtend *extend = (UserCustomExtend *)message.messageExtend.extendBody; label.text = extend.extendProperty; }
EM_ChatMessageExtendView本身没有太多可以实现的(后期会加入更多的实现),和```EM_ChatMessageBodyView```(用来显示消息内容的View)一样都是继承自```EM_ChatMessageContent```。你可以重写```EM_ChatMessageContent```的一些方法来实现更多的功能。
