Question

I’m new in Cocoa.

I have NSString – (e.g) MUSIC . I want to add some new NSString in Array,
And want to check something like this

if MUSIC already contained in Array, add Music_1 , after Music_2 and so on.

So I need to be able read that integer from NSString, and append it +1 .

Thanks

Use

NSString *newString = [myString stringByAppendingString:[NSString stringWithFormat:@"_%i", myInteger]];

if myString is “music”, newString will be “music_1” or whatever myInteger is.

EDIT: I seem to have gotten the opposite meaning from the other answer provided. Can you maybe clarify what it is you are asking exactly?
