Sure, replace:
[feeds insertObject:[item copy] atIndex:index];
with:
NSString *strToEvaluate = item[@"description"];
NSString *word = @"facebook";
NSString *word2 = @"news";
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains[c] %@", word];
NSPredicate *predicate2 = [NSPredicate predicateWithFormat:@"SELF contains[c] %@", word2];
if([predicate evaluateWithObject:strToEvaluate] || [predicate2 evaluateWithObject:strToEvaluate]) {
[feeds insertObject:[item copy] atIndex:index];
}
Or you can also use regularExpression
.
