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。
