IDE及测试环境:
xcode 11.3.1(11C504)
iPhone设备:iOS13.3.1
微信 v7.0.11
问题描述:
集成微信支付已经成功,但是不走回调,也就是说APP不能立即知道是不是支付成功了。
好些场景情况下,我们是要作些处理的,这样更加的提高用户的体验,比如说充值,我们需要立即给用户的余额加上。
解决方法:
1)在iOS13中,引入了分屏,这个是之前没有的,当您用xcode11建一个新的工程的时候,会发现多了一个SceneDelegate文件,这个文件就包括了场景Scene
这里面可以建window对象,也就是说这个从AppDelegate中分离出来了,目的就是为了支持分屏。
这种情况下,微信支付回调,会走SceneDelegate
2)那么如何处理呢,有些设备因为比较老,还不是iOS13,比如iOS12等等,有些微信的版本并没有超过7.0.5,那么微信支付还是会走AppDelegate
3) 这样的话,我们既要满足iOS13, 又要满足之前的版本,可以作以下处理:
3.1)加入版本判断
3.2)将以前不支持的SceneDelegate,加入进来即可
下面是具体的实现:
- 在AppDelegate加入方法,让AppDelegate知道有SceneDelegate
-
//这个方法就是将SceneDelegate关联起来
@available(iOS 13.0, *) func application(_ application: UIApplication, configurationForConnecting connectingSceneSession: UISceneSession, options: UIScene.ConnectionOptions) -> UISceneConfiguration { // Called when a new scene session is being created. // Use this method to select a configuration to create the new scene with. return UISceneConfiguration(name: "Default Configuration", sessionRole: connectingSceneSession.role) }
//这个方法也可以不加 @available(iOS 13.0, *) func application(_ application: UIApplication, didDiscardSceneSessions sceneSessions: Set<UISceneSession>) { // Called when the user discards a scene session. // If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions. // Use this method to release any resources that were specific to the discarded scenes, as they will not return. }//这个方法加一个if,通过不同的版本来干不同的活。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { //注册微信打印日志 WXApi.startLog(by: WXLogLevel.init(rawValue: 1)!) { (msg) in print(msg) } //注册APPID let result = WXApi.registerApp(WX_APPID, universalLink: WX_UniversalLink) print(result) if #available(iOS 13.0, *) { print("如果是iOS13,那么进入scene") }else{ window = UIWindow() window?.frame = UIScreen.main.bounds window?.rootViewController = ViewController() window?.makeKeyAndVisible() } return true }
