comparing string to an NSMutable array.

Question

hi all, another quick question. how to compare an string with the values of an array for example

string a =@"abc";

compare = [[NSMutableArray arrayWithObjects:@"a",@"b",@"abc",@"d",nil]];

if string matches any of the element in array, i should show some alert or something.

regards

Answer 1

if ([compare containsObject:a]) {
   // show alert;
}

If that array will become arbitrarily long, it's better to use an NSSet instead.
