Now I kinda succeded in establishing a communication between my app and my php WS, but I have some problems with types.

I created the WS using phpxmlrpc library, do you know if it's compatible with the wordpress library? I sometimes find that I dont get returned a NSDictionary but a String.

I also would like to know how to send integers or other types to the WS, not only strings.

Thanks!

Terminating app due to uncaught exception 'NSInvalidArgument
Exception', reason: '*** +[NSString decodeXMLCharactersIn:]: unrecognized selector sent to class 0×30692800'

I debugged and found that it crashes on the first line of this function:

- (id)decode
{
[_parser parse];

NSError *parseError = [_parser parserError];
if (parseError) {
return parseError;
}

return decodedValue;
}

Even though, I still don't know what I'm doing wrong. Some advice would be very helpful.

Thanks!

<methodResponse>
<params>
<param>
<value>
<boolean>0</boolean>
</value>
</param>
</params>
</methodResponse>

I tried using “boolean” and “value” as the key, but that didn't help, I get a “Terminating app due to uncaught expcetion NSUNknownKeyException, reason: NSCFBoolean 0x… valueForUndefineKey: this class is not key value coding-compliant for the key boolean/value/…”

Does the key relate to the XML at all?

Try logging some notices in the app to see where it is failing, eg:
if( [response isKindOfClass:[NSError class]] ) {
NSLog(@”Something went wrong … there was no readable response”);
return nil;
}
else {
NSLog(@”key: %@”,[response valueForKey:@"key"]);
return [response valueForKey:@"key"]; // the response key
}
return nil;

Where 'key' is some data you expect to get back from the server.

thanks for the info. I need to use XMLRPC for my iPhone app, I tried implementing an example pretty much like what Leo has on his site (http://www.leoganda.net/xml-rpc-on-iphone/). Even if I define response as an id and not NSString, I get a “NSInvalidArgumentException, reason: *** [NSError object]: unrecognized selector sent to instance …” error when I return the response as an object. Have you encountered this as well?

Thanks
