PZSlideMenu

一个抽屉效果

• 1.能过管理多个ViewController
• 2.支持滑动手势

##使用方法

    RootViewController * rootVC = [[RootViewController alloc] init];
    SecondViewController * secondVC = [[SecondViewController alloc] init];
    LeftViewController * leftVC = [[LeftViewController alloc] init];
    PZSlideMenu * menu = [[PZSlideMenu alloc] initWithLeftVC:leftVC viewControllers:@[rootVC, secondVC]];

//    menu.openOffset = 180;
//    menu.scale = 0.7;
    self.window.rootViewController = menu;
