NSUserDefaults对每个项目都是唯一的

Question

在我的应用程序中，我有很多工厂使用这种类型的代码，除非我希望用户为他们查看的每个工厂保存他们自己的注释，否则效果很好......

在我的PerennialDataPurple.h

中

//  PerennialDataPurple.h
//  Created by John Lein Feb. 2017.
//  Copyright (c) 2017 Lein Design Inc. All rights reserved.

@interface PerennialDataPurple : NSObject

@property (nonatomic, strong) NSString* name;

@property (nonatomic, strong) NSString* namethumb;

... 

@property (nonatomic, strong) NSString* image3Title;

*@property (nonatomic, strong) NSString* save_userNote;*

+(NSArray* )createMultipleSampleDishes;

@end

在我的PerennialDataPurle.m中，我有以下代码，除了再次保存笔记外...

//  PerennialDataPurple.m
//  Created by John Lein Feb. 2017.
//  Copyright (c) 2017 Lein Design Inc. All rights reserved.

#import "PerennialDataPurple.h"

@implementation PerennialDataPurple

+(NSArray* )createSampleDishes{

PerennialDataPurple* purpleconeflower = [[PerennialDataPurple alloc] init];
purpleconeflower.name = @"Purple Cone Flower";
purpleconeflower.namethumb = @"Purple\rCone Flower";
... 
purpleconeflower.image3Description = @"Put some information in here to describe the design feature of image 3";
purpleconeflower.save_userNote = [[NSUserDefaults standardUserDefaults] stringForKey:@"userNotes"];

我的详细控制器（PicDetailController.h）（除了save_userNote之外的工作）

//
//  PicDetailController.h
//
//  Created by John Lein Feb. 2017.
//  Copyright (c) 2017 Lein Design Inc. All rights reserved.
//

#import <UIKit/UIKit.h>
#import "PerennialDataYellow.h"
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#import "SMPageControl.h"

@interface PicDetailController : UIViewController   <NSFetchedResultsControllerDelegate, UIActionSheetDelegate, UIAlertViewDelegate, MFMailComposeViewControllerDelegate, UIScrollViewDelegate>

{

//    NSString *save_userNote;

    BOOL pageControlBeingUsed;
    UIImage *blurrredImage;

    BOOL didEdit;
    IBOutlet UITextView *userNotes;

}

// allows me to use the plant label over again...

@property (nonatomic, strong) IBOutlet UILabel *plantnameLabel;

@property (nonatomic, strong) IBOutlet UILabel *plantnameLabel2;

...

@property (nonatomic, retain) IBOutlet UITextView *userNotes;

- (IBAction)handleSingleTap:(id)sender;

- (IBAction)emailButton:(id)sender;

- (IBAction)saveAction:(id)sender;

- (IBAction)clearNote:(id)sender;

@end

我的详细控制器（PicDetailController.m）可以正常工作，它确实保存了save_userNotes，但它为我查看的每个工厂保存了相同的注释。因此，虽然它成功保存了用户输入的注释，但它并不是每个记录（工厂）都是唯一的...我不会在PerennialDataPurple.h文件中回调这个东西来建立连接......

//  PicDetailController.m
//  Created by John Lein Feb. 2017.
//  Copyright (c) 2017 Lein Design Inc.. All rights reserved.

- (void)saveAction:(id)sender
{

NSString *valueToSave = userNotes.text;
[[NSUserDefaults standardUserDefaults] setObject:valueToSave forKey:@"userNotes"];
[[NSUserDefaults standardUserDefaults] synchronize];

}

- (void) viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];

NSString *text = [[NSUserDefaults standardUserDefaults]objectForKey:@"userNotes"];
self.userNotes.text = text;

}

注意在第一张图片中 - 用户输入的注释已保存...如果我杀了应用程序，强制退出，并返回它保存...但是没有保存到每个工厂的独特......所以当我查看第二张或第三张或第四张图像时，相同的用户注释出现......

任何想法如何使这项工作如此EACH用户注释是每个工厂独有的......

我感谢任何帮助或见解...
