[英]How to handle push notification click in iOS Swift?
我正在嘗試處理推送通知點擊。 當推送通知進來時,我想在點擊推送通知后將用戶引導到應用程序的某個部分。 首先,應用程序中有 SplashScreen,它通過檢查用戶之前是否從 API 調用登錄,將 TabBar 顯示為“Present Modally”。 我想向用戶顯示的是 TabBar 第一個選項卡中導航 controller 中表格視圖中提要的內容。 但我無法到達它並將其顯示為單擊 tableview。
-SplashScreen -------> TabBar -> Navigation Controller -> Table View Controller -> ContentView(我想顯示)
我嘗試編寫 UIApplication 擴展,但沒有成功。 這是擴展名
extension UIApplication {
class func topViewController(base: UIViewController? = (UIApplication.shared.delegate as! AppDelegate).window?.rootViewController) -> UIViewController? {
if let nav = base as? UINavigationController {
return topViewController(base: nav.visibleViewController)
}
if let tab = base as? UITabBarController {
if let selected = tab.selectedViewController {
return topViewController(base: selected)
}
}
if let presented = base?.presentedViewController {
return topViewController(base: presented)
}
return base
}
}
我在 didFinishLaunchingWithOptions 中編寫了以下代碼
if let option = launchOptions {
let info = option[UIApplication.LaunchOptionsKey.remoteNotification] as? [String:Any]
if let info = info {
if info["type"] as! String == "site-notification" {
let contentVC = Destination().FeedCoontentVC
contentVC.selectedSite = (info["link"] as! String)
contentVC.title = "asd"
UIApplication.topViewController()?.present(contentVC, animated: true, completion: nil)
}
}
}
if info["type"] as! String == "site-notification" {
let tabbarSB = UIStoryboard(name: StoryBoard.tabBar, bundle: nil)
let tabbarVC = tabbarSB.instantiateViewController(withIdentifier: ViewController.TabBar) as! TabBarController
self.window?.rootViewController = tabbarVC
tabbarVC.viewControllers = [] // add your tab view controllers
for child in (tabbarVC.childViewControllers) {
if child.restorationIdentifier == "tablevc" //add restoration id to storyboard {
tabbarVC.selectedIndex = 1
let tableVC = (child.childViewControllers[0]) as! TableViewController
let contentSB = UIStoryboard(name: StoryBoard.contentSB , bundle: nil)
let contentVC = contentSB.instantiateViewController(withIdentifier: ViewController.contentVC ) as! FeedCoontentVC
contentVC.selectedSite = (info["link"] as! String)
contentVC.title = "asd"
tableVC.navigationController?.pushViewController(contentVC, animated: false)
}
}
}
