Swift中的CTCallCenter [英] CTCallCenter in Swift

问题描述

我正在尝试在Swift中使用CTCallCenter，但是它始终显示错误.

I'm trying to use CTCallCenter in Swift, however it always displays error.

我想这可能会导致如何使用闭包，但实际上我对此并不熟悉.

I suppose it may cause in how to use closure but actually I don't familiar about it.

有人有解决此问题的想法吗?

Does anybody have idea to resolve this issue?

这是我的代码

import CoreTelephony

class ViewController: UIViewController{

    var callCenter:CTCallCenter = CTCallCenter()

    override func viewDidLoad() {

           callCenter.callEventHandler(call:CTCall) -> Void in{
                //will get CTcall status here
           }
    }
}

有三个错误.

1，括号内的语句块是未使用的闭包

1, Braced block of statements is an unused closure

2，期望的表达方式

3，一行上的连续语句必须用;"分隔.

3, Consecutive statements on a line must be separated by ";".

我试图按照指示进行更改，但是任何方法都不正确.

I tried to change as it indicated but any ways are not correct.

预先感谢！

推荐答案

我使用以下代码进行了这项工作:

I got this working using the following code:

import CoreTelephony

class SomeClass: UIViewController {

    private var callCenter = CTCallCenter()

    override func viewDidLoad() {
        super.viewDidLoad()

        callCenter.callEventHandler = { (call:CTCall!) in

            switch call.callState {
                case CTCallStateConnected:
                    println("CTCallStateConnected")
                    self.callConnected()
                case CTCallStateDisconnected:
                    println("CTCallStateDisconnected")
                    self.callDisconnected()
                default:
                    //Not concerned with CTCallStateDialing or CTCallStateIncoming
                    break
            }
        }
    }

    func callConnected(){
        // Do something when call connects
    }

    func callDisconnected() {
        // Do something when call disconnects
    }
}
