Here is what I'm running on the button push with no response / errors or anything else:
NSArray *keys = [NSArray arrayWithObjects:@"MyName", nil];
NSArray *objects = [NSArray arrayWithObjects:@"jeremy", nil];
NSDictionary *params = [NSDictionary dictionaryWithObjects

bjects forKeys:keys];
NSDictionary *wsResponse=[WebServices callRestService:@"HelloName"

arams];
NSString *responseString=[wsResponse objectForKey:@"string"];
MainText.text = responseString;
Let me know if you have any ideas and thanks in advance...
