如何从 iPhone 上的来电中获取来电者的电话号码

你好，我想构建一个应用程序，在来电时执行某些操作。但我认为手机需要在 iPhone 上越狱才能访问执行此操作的类。我想在手机不越狱的情况下做到这一点。

不可能。

但是，您可以使用 CoreTelephony 框架。

如果您想在来电或去电时执行任何操作，则必须使用此代码：

CTCallCenter *callCenter; //make it ivar if you are using ARC or handler will be auto-released...
callCenter = [[CTCallCenter alloc] init];
callCenter.callEventHandler=^(CTCall* call) {
    NSLog(@"Call id:%@", call.callID);
    [self callStateChange:call.callState andId:call.callID];
    if (call.callState==CTCallStateDialing) {
       NSLog(@"Call state:dialing");
    }
    if (call.callState==CTCallStateIncoming) {
       NSLog(@"Call state:incoming");
       //here you lower your speaking volume if you want
    }
    if (call.callState==CTCallStateConnected) {
       NSLog(@"Call state:connected");
    }
    if (call.callState==CTCallStateDisconnected) {
       NSLog(@"Call state:disconnected");
    }
};

但是当您的应用程序处于活动状态或从后台转到前台时，这将起作用。如果应用程序将杀死或暂停该应用程序，则该应用程序将不起作用。首先，您检测呼叫状态，然后立即显示本地通知。当单击查看详细信息时，再次显示您的应用程序。但这并没有得到苹果的批准，因为它会在后台发送电话。所以可能会有风险。

If you want to do anything when a call come or going then you have to use this code:

CTCallCenter *callCenter; //make it ivar if you are using ARC or handler will be auto-released...
callCenter = [[CTCallCenter alloc] init];
callCenter.callEventHandler=^(CTCall* call) {
    NSLog(@"Call id:%@", call.callID);
    [self callStateChange:call.callState andId:call.callID];
    if (call.callState==CTCallStateDialing) {
       NSLog(@"Call state:dialing");
    }
    if (call.callState==CTCallStateIncoming) {
       NSLog(@"Call state:incoming");
       //here you lower your speaking volume if you want
    }
    if (call.callState==CTCallStateConnected) {
       NSLog(@"Call state:connected");
    }
    if (call.callState==CTCallStateDisconnected) {
       NSLog(@"Call state:disconnected");
    }
};

but that will work when u app will active or go background to foreground. If app will kill or suspended the that will not work. First you detect state of call and then show a local notification immediately. And when click on view details then show ur app again. But this is not approved by apple because it will send phone call in background. So it may be risky.
