Can an iPhone app block phone calls?
提问by
Is it possible to write an application that will block incoming and outcoming phone calls? Or is the iPhone locked down too much? Thanks!
是否可以编写一个应用程序来阻止来电和来电？还是 iPhone 被锁定太多了？谢谢！

EDIT: See Rajan Maheshwari's answer below. CallKit now provides this. Even things that seemed they would never change, can change eventually.
编辑：请参阅下面的 Rajan Maheshwari 的回答。CallKit 现在提供了这个。即使是看起来永远不会改变的事情，最终也会改变。
Anything that modifies a user's ability to make or receive phone calls is going to run afoul of Apple's basic approach to third-party apps. There are a lot of things that are questionable and you might get away with. Blocking calls is clearly forbidden.
任何改变用户拨打或接听电话能力的行为都将违反 Apple 对第三方应用程序的基本方法。有很多事情是有问题的，你可能会侥幸逃脱。阻塞呼叫是明确禁止的。

It is now possible to detect and block unwanted phone calls from iOS 10and above.
现在可以检测和阻止来自iOS 10及更高版本的不需要的电话。
See the CallKitframework
查看CallKit框架
The CallKit framework (CallKit.framework) lets VoIP apps integrate with the iPhone UI and give users a great experience. Use this framework to let users view and answer incoming VoIP calls on the lock screen and manage contacts from VoIP calls in the Phone app's Favorites and Recents views.
CallKit also introduces app extensions that enable call blocking and caller identification. You can create an app extension that can associate a phone number with a name or tell the system when a number should be blocked.
CallKit 框架 (CallKit.framework) 允许 VoIP 应用程序与 iPhone UI 集成并为用户提供出色的体验。使用此框架可让用户在锁定屏幕上查看和接听传入的 VoIP 呼叫，并在电话应用程序的收藏夹和最近的视图中管理来自 VoIP 呼叫的联系人。
CallKit 还引入了支持呼叫阻止和呼叫者识别的应用程序扩展。您可以创建一个应用扩展，将电话号码与姓名相关联，或者告诉系统何时应该阻止某个号码。

It is possible in iOS 10.
在 iOS 10 中是可能的。
Here's how to do it ->
这是如何做到的->
1.Create a call directory extension
1.创建呼叫目录扩展
2.Block the incoming call ->
2.阻止来电 ->
class CustomCallDirectoryProvider: CXCallDirectoryProvider {
override func beginRequest(with context: CXCallDirectoryExtensionContext) {
let blockedPhoneNumbers: [CXCallDirectoryPhoneNumber] = [ phone Numbers here with country code! ]
for phoneNumber in blockedPhoneNumbers.sorted(by: <) {
context.addBlockingEntry(withNextSequentialPhoneNumber: phoneNumber)
}
context.completeRequest()
}
}
Note: If you are using callKit to receive incoming calls then there is no need to manually block other calls.
注意：如果您使用 callKit 接听来电，则无需手动阻止其他来电。

A number of events will potentially interrupt an application - incoming call, SMS message or calendar alert. If the user ignores the interruption your application will continue running. If not, it will terminate.
许多事件可能会中断应用程序 - 来电、短信或日历提醒。如果用户忽略中断，您的应用程序将继续运行。如果没有，它将终止。
See Apple docsfor more details.

An app has not access to the phone feature, and has no way to block a call.
The alternative is to wait for Apple to offer that feature in the future.
应用程序无法访问电话功能，也无法阻止呼叫。
另一种选择是等待 Apple 将来提供该功能。
In the meantime, you can
在此期间，您可以
- Ask your provider - some providers do that
- Create a custom ring tone (silent) to be associated to some number (no ring).
- 询问您的提供商 - 有些提供商会这样做
- 创建自定义铃声（静音）以与某个号码（无铃声）相关联。
