How to detect if any external libraries are calling [UIDevice currentDevice] uniqueIdentifier]?

Question

So, since Apple is now rejecting apps that access UDID, on our company\'s current project, we need to eliminate all APIs that make a call to this property:

[[UID         


        

Answer 1

It can be difficult to reliably determine if a closed-source library is actually calling a method, but there are some ways you can see if they might be:

• Using strings to see if "uniqueIdentifier" appears in the library, regardless of how it's used:

  $ strings libFoo.a | grep uniqueIdentifier

• Using nm or otool (see this answer)

• Using otx (see this answer)

These approaches can help turn up potential invocations that setting a breakpoint may miss.
