Product:iPhone SDK Product Version:6.1
Classification: Reproducible:Always
 
Summary:

In the 2013 WWDC session entitled "Using Store Kit for In-App Purchases", it says:

Use weak linking to support both iOS 6 and iOS 7 receipts
 [[NSBundle mainBundle] respondsToSelector:@selector(appStoreReceiptURL)];

However, when I run this on iOS 6 this call returns YES. If I then actually invoke it I get an unrecognized selector exception.

This happens even if I build against iOS 7 SDK but target iOS 6.

Steps to Reproduce:

Call: [[NSBundle mainBundle] respondsToSelector:@selector(appStoreReceiptURL)]

Expected Results:

Returns NO on iOS 6

Actual Results:

Returns YES

Regression:

Notes:

This also seems to happen with other methods that are decorated with the NS_AVAILABLE_MAC macro. For example, +[NSFileVersion temporaryDirectoryURLForNewVersionOfItemAtURL:]
