Track deallocated object for specific classes using XAspect

DeallocTracker.m

// Just copy the fllowing code into a .m file, and include the XAspect to you project. 
// Then you'll see console log messages when objects of specific classes were deallocated.
// The block `AspectPatch(-, void, dealloc)` will be invoked just before `-dealloc` aka 'before advise'.


// Using XAspect
#import <XAspect/XAspect.h>
// Headers for classes you want to track
#import <CMDPUserLogin/UAMLoginViewController.h>
#import <CMDPUserLogin/UAMLoginTableViewController.h>
#import <ReactiveCocoa/ReactiveCocoa.h>
#import "UAMPhoneRegisterationTableViewController.h"

    klasses = @[[UAMLoginViewController class],
