使用 DDMenuController 类的方法（非常好用的抽屉类）

#pragma mark - 界面配置左右导航条的按钮
    //[self configureLeftButton];//配置导航条左边按钮
    [self configureRightButton];//配置导航条右边按钮

上面是要在ViewDidLoad 里面调用的

下面是方法的实现
#pragma mark - 界面配置类
//配置导航条左边按钮
- (void)configureLeftButton {
    UIBarButtonItem *left = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"qr_toolbar_more_hl"] style:UIBarButtonItemStylePlain target:self action:@selector(handleLeftBack:)];
    self.navigationItem.leftBarButtonItem = left;

}
//配置导航条右边按钮
- (void)configureRightButton {
    UIBarButtonItem *right = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"qr_toolbar_more_hl"] style:UIBarButtonItemStylePlain target:self action:@selector(handleRightBack:)];
    self.navigationItem.rightBarButtonItem = right;

}
#pragma mark -action
//导航条左边按钮点击事件
- (void)handleLeftBack:(UIBarButtonItem *)item {
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
    DDMenuController *menuC  = delegate.menuController;
    [menuC showLeftController:YES];
}
//导航条右边按钮点击事件
- (void)handleRightBack:(UIBarButtonItem *)item {
    AppDelegate *delegate = (AppDelegate *)[UIApplication sharedApplication].delegate;
    DDMenuController *menuC  = delegate.menuController;
    [menuC showRightController:YES];
}

可以使用appdelegate

-(void)leftBtnClick
{
    [(DDMenuController *)[UIApplication sharedApplication].delegate.window.rootViewController showLeftController:YES];
    
}
