How to search through a NSMutableArray

Question

I have a NSMutableArray that I need to search for a string and return the key in the array where the string was found. So for example if I'm searching "ipod" and it's the 4th in the array, it would return 3 or whatever position the string is in. What's the best way to do this?

Answer 1

return [theArray indexOfObject:@"ipod"];

Reference: http://developer.apple.com/iphone/library/documentation/Cocoa/Reference/Foundation/Classes/NSArray_Class/NSArray.html#//apple_ref/occ/instm/NSArray/indexOfObject:.

Note that NSMutableArray inherits from NSArray, so any NSArray methods can be used on NSMutableArray too.
