如何通过网页上的按钮在iPhone上调用USSD电话？

How to make a USSD call on a iPhone from a button in a webpage?

我试过urlencode tel％3A * 141 ％23 但仍然无法工作。

I have tried the urlencode tel%3A*141%23 but that still does not work.

这可能是因为我可以通过Iphone上的联系人应用程序执行USSD呼叫吗？

This is possible cause I can do a USSD call from my contacts application on Iphone?

有没有人有这方面的解决方案，我甚至不需要USSD调用在后台运行
，只是为了进行USSD调用。

Does anyone have a solution for this, I don't even need the USSD call to run in the background, just to make the USSD call.

我已阅读 https://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/PhoneLinks.html 了解特殊字符 * 和＃

I have read https://developer.apple.com/library/ios/#featuredarticles/iPhoneURLScheme_Reference/Articles/PhoneLinks.html about the special characters * and #

但我的通讯录应用程式如何操作？

But how does my Contacts app do it?

推荐答案

联系人应用程序具有特殊特权，仅限于凡人开发者无法拥有的特权。

The contacts app has special privileges us mere mortal developers cannot possess.

*和＃字符是块在电话：URL中使用。

The * and # characters are blocked from being used in tel: URLs.
