Hello,

Try this...

NSPredicate *containsAuthorPredicate = [NSPredicate 
predicateWithFormat:@"(SELF like %@)", [self wikiID]];
NSArray *validAuthors = [authors filteredArrayUsingPredicate: 
containsAuthorPredicate];

if([validAuthors count] > 0)
{    
   NSLog(@"Yes");
} else {
   NSLog(@"No");
}


hth,

Jaime
