NSMutableArray addObjects - unrecognized-selector

Question

This is how I initialize my NSMutablearray. I copy the content of cityList into cityArray. Both are NSMutableArray. FYI, I declared the\'cityArray\' using extern.

Answer 1

An NSArray doesn't implement valueForKey:. Your want either an NSDictionary or use objectAtIndex:.

Your second section of code should read:

NSString *allCities = @"All Cities";
[cityArray addObject:allCities];
