ios - openfire 聊天服务器在发送表情符号时出错

Question

我在 openfire 聊天应用程序服务器中发送表情符号时发现了这个错误。请建议如何解决它。

Error Domain=GCDAsyncSocketErrorDomain Code=7 "Socket closed by remote peer" UserInfo={NSLocalizedDescription=Socket closed by remote peer}

Answer 1

使用 NSNonLossyASCIIStringEncoding 和 NSUTF8StringEncoding 对您的消息进行编码>

 NSString *messageStr = [NSString stringWithUTF8String:[textview.text UTF8String]];

 // encode message

 NSData *msgData = [textview dataUsingEncoding:NSNonLossyASCIIStringEncoding];
 NSString *goodMsg = [[[NSString alloc] initWithData:msgData encoding:NSUTF8StringEncoding] autorelease];

注意:如果您的客户端应用程序获取格式为\ue415 的表情符号，您可以在之后使用类似这样的方式转换它们:

- (NSString *) substituteEmoticons {

    NSString *res = [self stringByReplacingOccurrencesOfString:@"\ue415" withString:@":)"];
    res = [res stringByReplacingOccurrencesOfString:@"\ue403" withString:@":("];
    res = [res stringByReplacingOccurrencesOfString:@"\ue405" withString:@";-)"];
    res = [res stringByReplacingOccurrencesOfString:@"\ue418" withString:@":-x"];
        .....
    return res;
}
