I hope this helps you,.. add this line at .m file or create a separate class and integrate this code.

@implementation NSString (Contains)

- (BOOL) containsString: (NSString*) substring
{
NSRange range = [self rangeOfString : substring];
BOOL found = ( range.location != NSNotFound );
return found;
}    
@end
