Fix to Enable Display Features - Google Analytics iOS SDK
In the official Google Analytics iOS SDK documentation, this function call will enable Display Features in your app:
id tracker = [[GAI sharedInstance] defaultTracker]; // Enable Advertising Features. [tracker set:allowIDFACollection value:@YES];
Sadly, this causes an error, as
allowIDFACollection is an invalid key. The real way to enable display features is to call this method:
[[GAI sharedInstance].defaultTracker setAllowIDFACollection:YES];
Save yourself a few minutes of frustration. Build and be happy.
