xcode filter NSMutableArray elements by string contents

Question

I would like to filter NSMutableArray elements that contains "some" string. ListArchives is filled with string elements and listFiles must be a filtered one. XCode generates an alert at last posted line. What am doing wrong? any other method to filter elements of NSMutableArray?

NSString *match = @"*some*"; 
listFiles = [[NSMutableArray alloc] init];

NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF like[cd] %@", match];

listFiles = [listArchives filteredArrayUsingPredicate:sPredicate];

Answer 1

Try using contains instead of like , for example as follows:

NSString *match = @"some"; 
listFiles = [[NSMutableArray alloc] init];

NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF CONTAINS[cd] %@", match];

listFiles = [[listArchives filteredArrayUsingPredicate:sPredicate] mutableCopy];

If you want to search as 'like' operator. Lets say you have a NSArray with following contents :

static int count = 0;
NSArray *results = [NSArray arrayWithObjects:@"What was", @"What is", @"What will", nil];

NSString *targetString = @"What"
for (NSString *strObj in results)
{
    if ([strObj rangeOfString:targetString].location != NSNotFound){
        NSLog (@"Found: %@", strObj);
        count = count + 1;              
    }
}
NSLog(@"There were %d occurence of %@ string",count,targetString);

NSString *match = @"some";
listFiles = [[NSMutableArray alloc] init];
NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF BEGINSWITH[c] %@", match];
listFiles = [listArchives filteredArrayUsingPredicate:sPredicate];

For robust searching this can serve you as some what "Like" serve in SQL .
