Get NSString value from app on jailbroken device

Question

Is it possible to get value of hard coded NSString from app on jailbroken device(with reverse engineering for example):

NSString *mySecretString = [NSString stringWithFormat:@"stringValue"]; 

Can someone get value "stringValue"?

Answer 1

Use the 'strings' utility from binutils on the app binary. http://sourceware.org/binutils/docs-2.18/binutils/strings.html

Example:

root@jailbroken-iPhone:~# strings HelloWorld
Hello, World!
root@jailbroken-iPhone:~# _
