iphone - CoreTelephony Framework iOS 7

Question

Are there any Changes which will allow more in the CoreTelephony Framework in iOS 7?! I found the new Headerfiles here:

https://github.com/EthanArbuckle/IOS-7-Headers/tree/master/Frameworks/CoreTelephony.framework

So, does that mean that it is now allowed to use those methods?! Or are they still private?!

Answer 1

The last available documentation on Apple Dev is from March 15, 2010, covers iOS 4.0, and includes the following classes:

• CTCall
• CTCallCenter
• CTCarrier
• CTTelephonyNetwork

The only available documentation for iOS 7 updates include what Kogus posted as well as a single line that says "for updates, look at the header files". When you open up the framework in XCode, the following classes are available in iOS 7:

• CTCall
• CTCallCenter
• CTCarrier
• CTSubscriber
• CTSubscriberInfo
• CTTelephonyNetwork

Based on the iOS 7 note about radio technology, it looks like the most pertinent change is within the CTTelephonyNetwork class, with the addition of the currentRadioAccessTechnology property.

It looks like there is actually a LOT more available, just based on the github link. But I'm willing to bet that those are mostly private APIs. I think the safest approach would be to stick to public headers available in Xcode. To that end, the pertinent bits added in iOS 7 would be (with pre iOS 7 code removed):

/*
 * CTSubscriberTokenRefreshed
 *
 * Description:
 *     The name of the NSNotification sent when the carrier token is available.
 */
CORETELEPHONY_EXTERN NSString * const CTSubscriberTokenRefreshed  __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);

CORETELEPHONY_CLASS_AVAILABLE(7_0)
@interface CTSubscriber : NSObject

/*
 * carrierToken
 *
 * Description:
 *     A data blob containing authorization information about the subscriber.
 *
 *     May return nil if no token is available.
 */
@property (nonatomic, readonly, retain) NSData* carrierToken  __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);

And...

CORETELEPHONY_EXTERN NSString * const CTRadioAccessTechnologyLTE           __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);

/*
 * currentRadioAccessTechnology
 *
 * Discussion:
 *   The current radio access technology the device is registered with. May be NULL
 *   if device is not registered on any network.
 */
@property (nonatomic, readonly, retain) NSString* currentRadioAccessTechnology __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_7_0);

@end

Hope that helps.
