ios push notification and IDFA issue

Question

In my ios app I've used

 uuid = [[ASIdentifierManager sharedManager] advertisingIdentifier]

as udid for my push notification.

Today when I tried to publish my app, itunes asks me:

This app uses the Advertising Identifier to (select all that apply):

1. Serve advertisements within the app.
2. Attribute this app installation to a previously served advertisement.
3. Attribute an action taken within this app to a previously served advertisement.

I use the uuid only for push notification. which of the 3 options should I choose?

Thanks in advance.

Answer 1

[[UIDevice currentDevice] identifierForVendor]

Is the better choice. You offer one single identifier for a device, even if the settings are reset.

The value of this property is the same for apps that come from the same vendor running on the same device. A different value is returned for apps on the same device that come from different vendors, and for apps on different devices regardless of vendor.UIDevice#identifierForVendor

For more explanation, heres a good summary: iOS6 UDID - What advantages does identifierForVendor have over identifierForAdvertising?

So, in case you do not use the advertisingIdentifier at all for advertising, you shouldn't make use of this => unfortunately, your question regarding the 3 approaches is obsolete.

Answer 2

You should only use IDFA for advertising related purposes. It should not be used solely for uniquely identifying the device.

You can use IDFA for:

• frequency capping,
• conversion events,
• estimating the number of unique users,
• security and fraud detection,
• debugging

Consider using identifierForVendor class method of UIDevice.

If you want to know more about IDFA. I researched this topic and wrote an article about it here:
