回答：
自定义消息的@消息的编解码
编码参考：
- (NSData *)encode {
NSMutableDictionary *dataDict = [NSMutableDictionary dictionary];
[dataDict setObject:self.content forKey:@"content"];
if (self.extra) {
[dataDict setObject:self.extra forKey:@"extra"];
}
if (self.mentionedInfo) {
NSMutableDictionary *mentionedInfodic = [[NSMutableDictionary alloc] init];
[mentionedInfodic setObject:@(self.mentionedInfo.type) forKeyedSubscript:@"type"];
if (self.mentionedInfo.type == RC_Mentioned_Users) {
[mentionedInfodic setObject:self.mentionedInfo.userIdList
forKeyedSubscript:@"userIdList"];
}
[mentionedInfodic setObject:self.mentionedInfo.mentionedContent
forKeyedSubscript:@"mentionedContent"];
[dataDict setObject:mentionedInfodic forKey:@"mentionedInfo"];
}
NSData *data = [NSJSONSerialization dataWithJSONObject:dataDict
options:kNilOptions
error:nil];
return data;
}
解码参考：
- (void)decodeWithData:(NSData *)data {
__autoreleasing NSError *__error = nil;
if (!data) {
return;
}
NSDictionary *dictionary = [NSJSONSerialization JSONObjectWithData:data
options:kNilOptions
error:&__error];
RCDictionary *json = [[RCDictionary alloc] initWithDictionary:dictionary];
if (json) {
self.content = [json stringObjectForKey:@"content"];
self.extra = [json stringObjectForKey:@"extra"];
NSDictionary *mentionedInfoDic = [json objectForKey:@"mentionedInfo"];
[self decodeMentionedInfo:mentionedInfoDic];//调用下面方法进行解码
}
}
- (void)decodeMentionedInfo:(NSDictionary *)dictionary {//此方法在RCMessageContent中已经实现，直接调用即可
RCDictionary *mentionedInfoDic =
[[RCDictionary alloc] initWithDictionary:dictionary];
if (mentionedInfoDic) {
RCMentionedInfo *mentionedInfo = [[RCMentionedInfo alloc] init];
mentionedInfo.type =
[[mentionedInfoDic numberObjectForKey:@"type"] intValue];
if (mentionedInfo.type == RC_Mentioned_Users) {
mentionedInfo.userIdList = [mentionedInfoDic objectForKey:@"userIdList"];
}
mentionedInfo.mentionedContent =
[mentionedInfoDic objectForKey:@"mentionedContent"];
self.mentionedInfo = mentionedInfo;
}
}
