Old ways don't work any more:

// way 1

void *lib = dlopen("/Symbols/System/Library/Framework/CoreTelephony.framework/CoreTelephony", RTLD_LAZY);
NSString* (*getPhoneNumber)() = dlsym(lib, "CTSettingCopyMyPhoneNumber");

if (getPhoneNumber == nil) {
    NSLog(@"getPhoneNumber is nil");
    return nil;
}
NSString* ownPhoneNumber = getPhoneNumber();

// way 2

extern NSString* CTSettingCopyMyPhoneNumber();
NSString *phone = CTSettingCopyMyPhoneNumber();

Is it possible to detect a phone number of the device in iOS?

[UPDATE]

Provided method works on iOS 6.1.4 without JB and iOS 7.1.2 with JB

Thanks to user creker for hint!

To get number you have to use following way:

1. Code

-(NSString*) getMyNumber {
    NSLog(@"Open CoreTelephony");
    void *lib = dlopen("/Symbols/System/Library/Framework/CoreTelephony.framework/CoreTelephony",RTLD_LAZY);
    NSLog(@"Get CTSettingCopyMyPhoneNumber from CoreTelephony");
    NSString* (*pCTSettingCopyMyPhoneNumber)() = dlsym(lib, "CTSettingCopyMyPhoneNumber");
    NSLog(@"Get CTSettingCopyMyPhoneNumber from CoreTelephony");

    if (pCTSettingCopyMyPhoneNumber == nil) {
        NSLog(@"pCTSettingCopyMyPhoneNumber is nil");
        return nil;
    }
    NSString* ownPhoneNumber = pCTSettingCopyMyPhoneNumber();
    dlclose(lib);
    return ownPhoneNumber;
}

2. Build application without signing: enter image description here

3. Create xml file (entitlements.xml) with following content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
    <dict>
        <key>com.apple.coretelephony.Calls.allow</key>
        <true/>
        <key>com.apple.coretelephony.Identity.get</key>
        <true/>
    </dict>
</plist>

Where:

com.apple.coretelephony.Calls.allow — for calls

com.apple.coretelephony.Identity.get — for getting own number

4. Sing app with entitlements.xml Copy files in one folder:

./FolderForRunSinging/
    YourApp.app
    entitlements.xml

entitlements.xml - created xml

YourApp.app - binaries for your app copied from XCode files To find where your binaries you can use command:

$ls -la ~/Library/Developer/Xcode/DerivedData/ | grep YourApp

Path should be like this:

/Users/username/Library/Developer/Xcode/DerivedData/YourApp-cktasembftvbmqaaiiunvljdwocs/Build/Products/Debug-iphoneos/YourApp.app

Run singing command:

$codesign --sign='iPhone Developer: FirstName  SecondName (XXXXXXXX)’
--entitlements entitlements.xml YourApp.app

'iPhone Developer: FirstName SecondName (XXXXXXXX)' - name of your certificate in keychain

enter image description here

5. Copy application YourApp.app on your device using ssh to folder

/Applications

6. Restart springboard (run on device):

$su mobile -c uicache 1>/dev/null 2>&1

Working sample could be found on github

Result on iOS 7.1.2 (JB is required!):

Result on iOS 6.1.3 (works without JB and without special signature just build and run)

In order to use this API you need to sign your app with entitlement com.apple.coretelephony.Identity.get with boolean value set to true.
