    // ...
    UIButton *plus = [UIButton buttonWithType: UIButtonTypeCustom];
    [plus setImage:[UIImage imageNamed:@"plus"] forState:UIControlStateNormal];
    plus.frame = CGRectMake(185, 200, 40, 40);
    [plus addTarget:self action:@selector(addButton) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview: plus];
}

- (void)addButton {
    UIButton *btn5 = [UIButton buttonWithType: UIButtonTypeCustom];
    btn5.backgroundColor = [UIColor grayColor];
    [_ExpandMenuButton addOneButton:btn5];
}

[_ExpandMenuButton addOneButton:btn];
