零.环信小结,以备后用
一. Cocoapods 集成
不包含实时语音版本 SDK（HyphenateLite），引用时 #import <HyphenateLite/HyphenateLite.h>
pod 'HyphenateLite'
包含实时语音版本 SDK（Hyphenate），引用时 #import <Hyphenate/Hyphenate.h>
pod 'Hyphenate'
二.依赖库相关
忘了,第一步集成完成后编译下,编译如果成功的话,那就忽略这一步,如果编译失败,去环信官网瞅瞅吧!
三.初始化
1.在全局文件中导入相关文件,或者是需要使用的文件中导入
//Lite版本
#import <HyphenateLite/HyphenateLite.h>
//Full版本
#import <Hyphenate/Hyphenate.h>
2.在 AppDelegate 中调用SDK方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// 环信
EMOptions *options = [EMOptions optionsWithAppkey:@"1155170XXXXXXX37#xiubei"];
options.apnsCertName = @"xXXXXei_push";
[[EMClient sharedClient] initializeSDKWithOptions:options];
[[EaseSDKHelper shareHelper] hyphenateApplication:application
didFinishLaunchingWithOptions:launchOptions
appkey:@"115517092XXXX37#xiubei"
apnsCertName:@"xXXXXei_push"
otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
}
// APP进入后台
- (void)applicationDidEnterBackground:(UIApplication *)application
{
[[EMClient sharedClient] applicationDidEnterBackground:application];
}
// APP将要从后台返回
- (void)applicationWillEnterForeground:(UIApplication *)application
{
[[EMClient sharedClient] applicationWillEnterForeground:application];
}
四.登陆且注册环信相关方法
EMError *error1 = [[EMClient sharedClient] loginWithUsername:_loginView.phoneTF.text password:_loginView.pwdTF.text];
if (!error1) {
NSLog(@"登录成功");
[[EMClient sharedClient].options setIsAutoLogin:YES];
}else{
NSLog(@"登录失败 ： error = %@",error1.errorDescription);
EMError *error = [[EMClient sharedClient] registerWithUsername:_loginView.phoneTF.text password:pwd];
if (error == nil) {
NSLog(@"注册成功");
}else{
NSLog(@"注册失败 ： error = %@",error.errorDescription);
}
}
** 五.导入EaseUI**
下载官方demo,导入整个EaseUI目录,[ 环信下载地址 ](http://www.easemob.com/download/im)
615D47FCF21652DD5C8E64843F754B80.jpg
六.导入 ChatDemoHelper 类
七.新建 MSUMessageController 和 MSUMessageChatController两个类,分别继承于 EaseConversationListViewController 和 EaseMessageViewController,相关代码拷贝放入其中

2. MSUMessageController.m 内容 (其他具体内容视情况而定)

八.环信消息推送
1.[ 开发者账号证书配置 ](http://www.jianshu.com/p/eb8d9493bc9d)
2.[ 上传推送证书到环信 ](http://docs.easemob.com/im/300iosclientintegration/apns)
3.在 didFinishLaunchingWithOptions 中 初始化环信及环信推送
/* EM 环信 */
- (void)setUpEMSomething{
EMOptions *options = [EMOptions optionsWithAppkey:@"115517XXXX115537#xiubei"];
options.apnsCertName = @"xiubei_develop";
[[EMClient sharedClient] initializeSDKWithOptions:options];
EMPushOptions *emoptions = [[EMClient sharedClient] pushOptions];
emoptions.displayStyle = EMPushDisplayStyleMessageSummary;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[[EMClient sharedClient] updatePushOptionsToServer];
});
[[EaseSDKHelper shareHelper] hyphenateApplication:application
didFinishLaunchingWithOptions:launchOptions
appkey:@"115517XXXX115537#xiubei"
apnsCertName:@"xiubei_develop"
otherConfig:@{kSDKConfigEnableConsoleLogger:[NSNumber numberWithBool:YES]}];
[[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
}
4.注意点
1)未上线前,通过更改 options.apnsCertName ,来进行上线和未上线的区别(证书名字在请看第2步 - 环信证书上传步骤)
2)推送显示消息内容 是 "一条新消息"还是消息详情内容,设置属性 emoptions.displayStyle
EMPushOptions *emoptions = [[EMClient sharedClient] pushOptions];
emoptions.displayStyle = EMPushDisplayStyleMessageSummary;
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
[[EMClient sharedClient] updatePushOptionsToServer];
});
九.问题小结
1. 自定义 列表视图的 tableview 高度,根据自己需求调整!
方法:- (void)chatToolbarDidChangeFrameToHeight:(CGFloat)toHeight
BB7AE49930F859B4C63B1BDA7D9B29AB.jpg
2.messageChatController 即私信对话框页面,不能实现 scrollView代理隐藏键盘,不然聊天记录超过半屏后会造成屏幕卡住,私聊页面无法使用情况!
3.在 tableViewDidTriggerHeaderRefresh 方法里面,对接服务器,获取聊天列表头像和昵称!
4.在 EaseConversationListViewController 中的 tableViewDidTriggerHeaderRefresh 方法中请求服务器,获取会话列表相关信息!
