任何人都可以给我一个提示或如何从网站上获取该代码吗？
Can anyone give me a hint or how to get that code from the website?
谢谢。
这不适用于非越狱的iOS设备 - 应用程序沙箱防止它。如果您知道他们实现的URL方案（例如，电话应用程序的 tel：// ），则可以通过调用 [来测试某些单独的应用程序[UIApplication sharedApplication] canOpenURL：[NSURL URLWithString：@someScheme：// blah]] ，但如果应用程序没有响应任何URL方案，那么你将无法确定它是否出现在设备上。
This is not possible on non-jailbroken iOS devices—the app sandbox prevents it. You can test for some individual applications, if you know the URL schemes they implement (e.g. tel:// for the Phone app), by calling [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"someScheme://blah"]], but if an app doesn’t respond to any URL schemes then you’re not going to be able to determine whether it’s present on the device.
