Adding Rotten Tomates API to iphone app - ios

Question

Im trying to add Rotten Tomatoes API to my app but it doesn't seem to like it? What am I doing wrong?? The error says "Data Argument not used by format string"
-(void)main {
NSLog(#"Service has run");
NSString *api_key = #"j4jz49tvf76cmnb4mwfyjvyt";
NSString *search_term = [searchTerm stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSString *url = [NSString stringWithFormat:#"http://api.rottentomatoes.com/api/public/v1.0/lists/movies/box_office.json?limit=16&country=us&apikey=j4jz49tvf76cmnb4mwfyjvyt", api_key, search_term];
NSURLRequest *theRequest=[NSURLRequest requestWithURL:[NSURL URLWithString:url]
cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSData *responseData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:nil error:nil];
if (responseData !=nil) {
NSError *error =nil;
NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData
options:kNilOptions error:&error];
if (error) {
[delegate serviceFinished:self withError:YES];
} else {
results = (NSArray *) [json valueForKey:#"movies"];
[delegate serviceFinished:self withError:NO];
}
} else {
[delegate serviceFinished:self withError:YES];
}
}
#end

Your error is on this line
NSString *url = [NSString stringWithFormat:#"http://api.rottentomatoes.com/api/public/v1.0/lists/movies/box_office.json?limit=16&country=us&apikey=j4jz49tvf76cmnb4mwfyjvyt", api_key, search_term];
String with format works with adding a data argument like %# in a string as a placeholder, and then replacing that with the following arguments in your method call.
What you want to do is probably something like:
NSString *url = [NSString stringWithFormat:#"http://api.rottentomatoes.com/api/public/v1.0/lists/movies/box_office.json?limit=16&country=us&apikey=%#&search_term=%#", api_key, search_term];
