Disconnect or connect an iPhone call programmatically

Question

I\'m working on a personal tweak for iOS. I want to disconnect/connect a phone call before the phone would show anything. I\'m hooking into the initWithAlertController

Answer 1

For iOS 8.*:

The hooking seems pretty easy with Theos/Logos.

Example Tweak.xm file (you need the TelephonyUtilities private framework headers for 8.1):

#import "TelephonyUtilities/TUTelephonyCall.h"

%hook MPTelephonyManager

-(void)displayAlertForCall:(TUTelephonyCall*)phoneCall { // for iOS 9: displayAlertForCallIfNecessary
    NSLog(@"hooked displayAlertForCall method");
    if ([[NSBundle mainBundle].bundleIdentifier isEqualToString:@"com.apple.springboard"]) { // (don't know if required)
        [phoneCall answer]; // or [phoneCall disconnect];
    }
    %orig;
}

%end


%ctor {
    if ([[NSBundle bundleWithPath:@"/System/Library/SpringBoardPlugins/IncomingCall.servicebundle"] load]) {
        NSLog(@"IncomingCall.servicebundle loaded succesfully!");
    }
    else {
        NSLog(@"IncomingCall.servicebundle did not load succesfully.");
    }
}
