openfire聊天服务器在发送表情符号时发出错误

Question

我在openfire聊天应用服务器中发送表情符号时发现此错误。请建议如何解决。

Answer 1

使用NSNonLossyASCIIStringEncoding和NSUTF8StringEncoding

对您的邮件进行编码

 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将表情符号格式化为\ ue415，您可以使用以下内容对其进行转换：

- (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;
}
