Summary:

When using XCode refactoring to rename a property which is autosynthesized, and the implementation contains references to the autogenerated ivar (property name prefixed with one underscore), these references are not renamed.

Steps to Reproduce:

1) Create a test class as follows:

//  renameTest.h

#import <Foundation/Foundation.h>

@interface renameTest : NSObject

@property (strong, nonatomic) id testProperty;

@end



//  renameTest.m

#import "renameTest.h"

@implementation renameTest

- (id)init
{
  self = [super init];
  if (self) {
    _testProperty = nil;
  }
  return self;
}

@end


2) Use XCode refactor->rename to rename testProperty.

Expected Results:

references to the autogenerated ivar _testProperty should be renamed to match the new property name

Actual Results:

reference to _testProperty remains unchanged


Notes:

With the new autosynthesizing properties, the existence of the _ivar is no longer only a convention, but a inevitable consequence of declaring a property without providing setter AND getter. So refactor->rename should take care of renaming the _ivar.
