IOS 運用內顯示 AppStore 某個運用的概況

編輯:IOS開發綜合

媒介

  運用內跳轉到 AppStore 的文章許多,普通都是用 SKStoreProductViewController 來完成的,不曉得有無在乎一個成績:翻開很慢!!怎樣忍?!

 注釋

  普通網上的文章的代碼:

 func openAppStore(url: String){
  if let number = url.rangeOfString("[0-9]{9}", options: NSStringCompareOptions.RegularExpressionSearch) {
   let appId = url.substringWithRange(number)
   let productView = SKStoreProductViewController()
   productView.delegate = self
   productView.loadProductWithParameters([SKStoreProductParameterITunesItemIdentifier : appId], completionBlock: { [weak self](result: Bool, error: NSError?) -> Void in
    if result {
     self?.presentViewController(productView, animated: true, completion: nil)
    } else {
     self?.openAppUrl(url)
    }
   })
  } else {
   openAppUrl(url)
  }
 }
 
 private func openAppUrl(url: String) {
  let nativeURL = url.stringByReplacingOccurrencesOfString("https:", withString: "itms-apps:")
  if UIApplication.sharedApplication().canOpenURL(NSURL(string:nativeURL)!) {
   UIApplication.sharedApplication().openURL(NSURL(string:url)!)
  }
 }
 
 func productViewControllerDidFinish(viewController: SKStoreProductViewController) {
  viewController.dismissViewControllerAnimated(true, completion: nil)
 }

完成的後果很好,就是很慢,點擊按鈕挪用 openAppStore 要良久能力顯示出界面,就算加一個轉圈後果也很差。緣由是由於要去  linkmaker.itunes.apple.com 依據 identifier 查找鏈接,細心看代碼我們會發明 presentViewController 是在查找到成果才被挪用,其實我們可以不消讓界面現出來,固然時光是一樣的,然則用戶體驗會很好,修正子女碼以下:

func openAppStore(url: String){
  if let number = url.rangeOfString("[0-9]{9}", options: NSStringCompareOptions.RegularExpressionSearch) {
   let appId = url.substringWithRange(number)
   let productView = SKStoreProductViewController()
   productView.delegate = self
   productView.loadProductWithParameters([SKStoreProductParameterITunesItemIdentifier : appId], completionBlock: { [weak self](result: Bool, error: NSError?) -> Void in
    if !result {
     productView.dismissViewControllerAnimated(true, completion: nil)
     self?.openAppUrl(url)
    }
   })
   self.presentViewController(productView, animated: true, completion: nil)
  } else {
   openAppUrl(url)
  }
 }
 
 private func openAppUrl(url: String) {
  let nativeURL = url.stringByReplacingOccurrencesOfString("https:", withString: "itms-apps:")
  if UIApplication.sharedApplication().canOpenURL(NSURL(string:nativeURL)!) {
   UIApplication.sharedApplication().openURL(NSURL(string:url)!)
  }
 }
 
 func productViewControllerDidFinish(viewController: SKStoreProductViewController) {
  viewController.dismissViewControllerAnimated(true, completion: nil)
 }

代碼解釋:

    不等 loadProductWithParameters 前往直接 presentViewController ,解析掉敗再測驗考試用 openURL 的方法翻開。
