Receiving an unrecognized selector error

Question

Here's what I'm trying to do:

I'm attempting to pass a string from a UITableView selection into a web service and return a data set. When I hard code the parameter, the code works fine. When using the code below, I get this error:

-[NSCFString stringByReplacingOccurencesOfString:withString:]: unrecognized selector sent to instance 0x6054

-(void) getStateData 
{
    stateWebService = [[NSMutableData data] retain];
    NSMutableURLRequest *request = [[NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.**********.com/webservices.asmx/getCGbyState?"]] retain];
    //[request appendString:_Campground.country];
    NSString *country = [_Campground.country stringByReplacingOccurencesOfString:@" " withString:@""];
    [request setHTTPMethod:@"POST"];
    NSString *postString = (@"country=%@",country);
    [request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
    NSURLConnection *myConnection = [NSURLConnection connectionWithRequest:request delegate:self];
    [myConnection start];
}

Can you provide the header for whatever class _Campground is? I suspect it's `country` member may not be an NSString. — Tim Reddy, Jan 06 '12 at 20:08
It's definitely an NSString. In the Campground.h file I have it declared with NSString *country; — tallybear, Jan 06 '12 at 20:12
I got it... It would help if I spelled Occurrences correctly... :-/ lol — tallybear, Jan 06 '12 at 20:16

You have a missing 'r' in stringByReplacingOccurencesOfString. It should be stringByReplacingOccurrencesOfString.

Yeah. Thanks. Lol. I figured it out right before I saw this. – tallybear Jan 06 '12 at 20:32
Man, how do see something like that, Eagle eyes for sure! – Hubert Kunnemeyer Jan 06 '12 at 20:52
Well Google helped me out :) I wanted to check on the documentation for the method and see if it had anything to with the error and searched for `stringByReplacingOccurencesOfString`, and the all seeing Big G said _Showing results for stringByReplacingOccurrencesOfString Search instead for stringByReplacingOccurencesOfString_ End of story :) – Krishna K Jan 06 '12 at 21:02
to easy I actually had to past one under the other and notice one was sorter than the other and double check every letter to come up with it. – Vincent Bernier Jan 06 '12 at 21:07

You are missing a "r" in stringByReplacingOccurrencesOfString

occurrences take 2 "r"

Where is _Campground.country defined? It is potentially getting released before you are calling stringByReplacingOccurencesOfString:withString: on it.

You can enable zombie objects to see what 0x6054 actually is.
