    NSError *error;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
    NSString *documentsDir = [[paths objectAtIndex:0] stringByAppendingString:@"/NewFolder/"];

    NSString *dbPath = [documentsDir stringByAppendingPathComponent:@"MyDB.sql"];
    BOOL success = [fileManager fileExistsAtPath:dbPath];

    if(!success) {

        NSString *defaultDBPath = [[NSBundle mainBundle] pathForResource:@"MyDB" ofType:@"sql"];

        success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];

        if (!success)
            NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);

Try to create directory by following code, may you get help..

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/YourFolder"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])//Check
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:&error]; //Will Create folder
