how to Send & symbol in xml body to server

问题

I am trying to send the & symbol to the server in an XML body but only received a blank. I tried HTML code to send this also but in vain.

回答1:

You can create a category on NSString and then encode few characters that you cant send directly... few are implemented below:

@implementation NSString (URLEncoding)

- (NSString *) stringByUrlEncoding{
    return (NSString *)CFBridgingRelease(CFURLCreateStringByAddingPercentEscapes(NULL,  (CFStringRef)self,  NULL,  (CFStringRef)@"!*'();:@&;=+$,/?%#[]",  kCFStringEncodingUTF8));
}

@end
