基于环信用户头像与昵称的集成

其中有一个扩张消息类的方法：

+ (EMMessage *)sendTextMessage:(NSString *)text

to:(NSString *)toUser

messageType:(EMChatType)messageType

messageExt:(NSDictionary *)messageExt；

在该方法中将你要赋予的用户头像和昵称进行赋值。（这里可以用登录时拿到的用户头像和昵称）

如下：

+ (EMMessage *)sendTextMessage:(NSString *)text

to:(NSString *)toUser

messageType:(EMChatType)messageType

messageExt:(NSDictionary *)messageExt

{

NSString *willSendText = [EaseConvertToCommonEmoticonsHelper convertToCommonEmoticons:text];

EMTextMessageBody *body = [[EMTextMessageBody alloc] initWithText:willSendText];

NSString *from = [[EMClient sharedClient] currentUsername];

//开始 设置 扩展类消息

NSMutableDictionary * dic = [[NSMutableDictionary alloc]init];

[dic setValue:userDic[@"username"] forKey:@"username"];

[dic setValue:userDic[@"userHeadImg"] forKey:@"userHeadImg"];

[dic setValue:userDic[@"userid"] forKey:@"userid"];

[dic setValue:userDic[@"phonenum"] forKey:@"phonenum"];

for (NSString *key in messageExt.allKeys) {

[dic setValue:messageExt[key] forKey:key];

}

EMMessage *message = [[EMMessage alloc] initWithConversationID:toUser from:from to:toUser body:body ext:[dic copy]];

// 结束

// EMMessage *message = [[EMMessage alloc] initWithConversationID:toUser from:from to:toUser body:body ext:messageExt];

message.chatType = messageType;

return message;

}

除此方法外： 发送语音、位置、图片的扩展消息中也需设置头像和昵称。
