Try this,This will result the array of values which contains matched string.

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSArray *renameArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:documentsDirectory  error:nil];

NSString *strprdicate = [NSString stringWithFormat:@"SELF CONTAINS '%@'",@"start"];
 NSPredicate *predicate = [NSPredicate predicateWithFormat:strprdicate];
renameArray =  [renameArray filteredArrayUsingPredicate:predicate];

NSLog(@"files array %@", renameArray);

Make sure you should pass input string in '' if input is a string for NSPredicate.
