1、初始化及登陆
在程序入口初始化SDK并设置代理 - 代理类设置最好放在didFinishLaunchingWithOptions中,代码示例如下：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
#warning 设置代理
[ECDevice sharedInstance].delegate = [DeviceDelegateHelper sharedInstance];
return YES;
}
代理类示例:
DeviceDelegateHelper.h文件 Class->Model
// 代理类.h文件如下
#import <Foundation/Foundation.h>
#import "ECDeviceHeaders.h"
#import "AppDelegate.h"
@interface DeviceDelegateHelper : NSObject<ECDeviceDelegate>
/**
*@brief 获取DeviceDelegateHelper单例句柄
*/
+ (DeviceDelegateHelper*)sharedInstance;
DeviceDelegateHelper.m文件
/**
* 第一步:创建单例方法
*
*/
+ (DeviceDelegateHelper*)sharedInstance{
static DeviceDelegateHelper *devicedelegatehelper;
static dispatch_once_t devicedelegatehelperonce;
dispatch_once(&devicedelegatehelperonce, ^{
devicedelegatehelper = [[DeviceDelegateHelper alloc] init];
});
return devicedelegatehelper;
}
/**
* 第二步:连接云通讯的服务平台,实现ECDelegateBase代理的方法
@brief 连接状态接口
@discussion 监听与服务器的连接状态 V5.0版本接口
@param state 连接的状态
@param error 错误原因值
*/
- (void)onConnectState:(ECConnectState)state failed:(ECError*)error {
switch (state) {
case State_ConnectSuccess: // 连接成功
[[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_onConnected object:[ECError errorWithCode:ECErrorType_NoError]];
break;
case State_Connecting: // 正在连接
[[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_onConnected object:[ECError errorWithCode:ECErrorType_Connecting]];
break;
case State_ConnectFailed: // 失败
[[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_onConnected object:error];
break;
default:
break;
}
}
第三步:各功能回调函数实现
/**

@param amplitude 录音振幅
*/
- (void)onRecordingAmplitude:(double) amplitude{
[[NSNotificationCenter defaultCenter] postNotificationName:KNOTIFICATION_onRecordingAmplitude object:@(amplitude)];

@param message 接收的消息

return;
}

ECTextMessageBody * textmsg = (ECTextMessageBody *)message.messageBody;
textmsg.text = [[EmojiConvertor sharedInstance] convertEmojiSoftbankToUnicode:textmsg.text];
}
#warning 时间全部转换成本地时间
if (message.timestamp) {
NSDate* date = [NSDate dateWithTimeIntervalSinceNow:0];
NSTimeInterval tmp =[date timeIntervalSince1970]*1000;
message.timestamp = [NSString stringWithFormat:@"%lld", (long long)tmp];
}
