前言

  应用内跳转到 AppStore 的文章很多,一般都是用 SKStoreProductViewController 来实现的,不知道有没有在意一个问题:打开很慢!!怎么忍?!

 正文

  一般网上的文章的代码:

 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) }

实现的效果很好,就是很慢,点击按钮调用 openAppStore 要很久才能显示出界面,就算加一个转圈效果也很差。原因是因为要去  linkmaker.itunes.apple.com 根据 identifier 查找链接,仔细看代码我们会发现 presentViewController 是在查找到结果才被调用,其实我们可以不用让界面现出来,虽然时间是一样的,但是用户体验会很好,修改后代码如下:

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) }

代码说明:

    不等 loadProductWithParameters 返回直接 presentViewController ,解析失败再尝试用 openURL 的方式打开。
