How to close the SideBar menu manually when using SWRevealViewController ( ios)
提问by moni_sind
I am trying to implement a SideBar/ slide out menu using the SWRevealViewController. I have a bunch of menus. One of the menu is to get app version info. So When I click on the cell, An AlertViewdisplays the version number and on pressing the OK button I would like to close/hide the SideBarmenu and return to the pervious view(front controller). For example, if I am on log in controller and I press the settings button to reveal the side bar and I choose version menu from TableViewcells, a pop will open displaying version# and when I press Ok, the SideBarshould close and return to the login screen without me having to tap the settings button again or swiping to return. How can I return to the login screen when I press OK on the alert view.
我正在尝试SideBar使用SWRevealViewController. 我有一堆菜单。菜单之一是获取应用程序版本信息。因此，当我单击单元格时，AnAlertView会显示版本号，然后按 OK 按钮，我想关闭/隐藏SideBar菜单并返回上一个视图（前控制器）。例如，如果我在登录控制器上并按下设置按钮以显示侧栏并从TableView单元格中选择版本菜单，则会弹出一个显示版本#的弹出窗口，当我按下确定时，SideBar应该关闭并返回登录我无需再次点击设置按钮或滑动即可返回。当我在警报视图上按 OK 时，如何返回登录屏幕。
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
// the user clicked OK
if (buttonIndex == 0) {
//close the side bar and return to front view controller
}
}

I just figured out the answer. I just use the following code to hide the side bar.
我刚刚想出了答案。我只是使用下面的代码来隐藏侧边栏。
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {
[self.revealViewController revealToggleAnimated:YES];
}
}

If anyone is looking for a swiftversion, just use this single line:
如果有人正在寻找swift版本，只需使用这一行：
self.revealViewController().revealToggleAnimated()

//View Did load add this // Swift 4.2
//查看是否加载添加了这个 // Swift 4.2
func viewDidLoad() {
super.viewDidLoad()
let leftMenuItem = UIBarButtonItem(image: UIImage(named: "menu"), style: .plain, target: revealViewController, action: #selector(SWRevealViewController.revealToggle(_:)))
navigationItem.setLeftBarButton(leftMenuItem, animated: true)
}
