Answer 1

You can use NSPredicate for this purpose.

For example:-

NSMutableArray *mutableArray = [array with objects];
NSPredicate *predictate = [NSPredicate predicateWithFormat:@"%K == %d",@"isDefault",1];
NSArray *filterArray = [mutableArray filteredArrayUsingPredicate:predictate];
NSLog(@"filterArray :%@",filterArray);

OR also you can try with this :-

NSMutableArray *matches = [[NSMutableArray alloc]init];
NSFileManager *manager = [NSFileManager defaultManager];

    NSString *item;
    NSArray *contents = [manager contentsOfDirectoryAtPath:[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"] error:nil];
    for (item in contents)
    {
        if ([[item pathExtension]isEqualToString:@".pdf"])
        {
            [matches addObject:item];
        }
    }
