Why are my objects changing unexpectedly?

Question

I\'ve got a very basic example where I\'m reading some data into a class from JSON, and my objects are getting corrupted somehow. I suspect I\'m missing some detail about how pr

This is not the root of yout problem but change your initWithJson: to

-(id)initWithJson:(NSDictionary *)jsonObject
{      
  if(!(self = [super init] ) ) { return nil; }    
  _references = jsonObject[@"references"];    
  return self;
}

Ditch the custom setter and getter (you obviously don't need them).

In your case you can declare property simply with:

@property (strong) NSArray* references;

Change the NSArray * _references; to:

@synthesize references = _references;

You can also omit the @synthesize line in your case.

Also change _references = jsonObject[@"references"]; to:

_references = [NSArray arrayWithArray:jsonObject[@"references"]];

To sum it all together:

ANBNote.h

@interface ANBNote : NSObject
@property (strong) NSArray* references;
- (id)initWithJson:(NSDictionary*)data;
@end

ANBNote.m

#import "ANBNote.h"

@implementation ANBNote

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

-(id)initWithJson:(NSDictionary *)jsonObject {      
  if(!(self = [super init] ) ) { return nil; }    
  _references = [NSArray arrayWithArray:jsonObject[@"references"]];    
  return self;
}

@end
