Require CoreTelephony framework examples.

Question

Greetings everyone.

Can any one has a working example for the CoreTelephony framework? I dumped all the CoreTelephony headers using class-dump and added them to "/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/System/Library/PrivateFrameworks/CoreTelephony.framework". Now I'm following the Erica's tutorial (http://blogs.oreilly.com/iphone/2008/08/iphone-notifications.html).

I added these following lines of code in my main.m,

  id ct = CTTelephonyCenterGetDefault();
  CTTelephonyCenterAddObserver(
        ct, 
        NULL, 
        callback,
        NULL,
        NULL,
        CFNotificationSuspensionBehaviorHold);

but I'm getting a warning like,

Implicit declaration of function "CTTelephonyCenterGetDefault()" and "CTTelephonyCenterAddObserver(...)".

Can any one has full working example, which will explain how to get the CoreTelepony notifications?

Answer 1

The warning "Implicit declaration of function" means that the compiler cannot find a definition for the function in the header.

If the functions are defined in the header then you most likely did not import them correctly.

I would also note that you should not put any code in the main.m of an iPhone app. Most of the important code does not load until UIApplication is launched. Put the code in the application delegate's applicationDidFinishLaunching: instead.

even using http://www.alexwhittemore.com/?p=281 - Open Tool Chain for 3.0 sdk (last tool chain i'd found) - i couldn't have CoreTelephony working - so it's seams to be impossible in last Xcode's/SDK's

prathumca, are you still having this issue? I have been successfully using this private framework. The warnings will not prevent your code from running, but you could put the following declaration in your code to get rid of the warning on CTTelephoneCenterGetDefault()

id CTTelephonyCenterGetDefault();
