在NSOrderedSet中生成的异常生成访问器 [英] Exception thrown in NSOrderedSet generated accessors

问题描述

在我的Lion应用程式上，我有这种资料模式：

subitems code> 已订购。

Xcode 4.1（build 4B110）为我创建了 h ， Item.m ， SubItem.h 和 SubItem .h 。

以下是 Item.h 的内容（自动生成）

  #import< Foundation / Foundation.h> 
 
 #import< CoreData / CoreData.h> 
 
 @class SubItem; 
 
 @interface项目：NSManagedObject {
 @private 
} 
 
 @property（nonatomic，retain）NSString * name; 
 @property（nonatomic，retain）NSOrderedSet * subitems; 
 @end 
 
 @interface Item（CoreDataGeneratedAccessors）
 
  - （void）insertObject：（SubItem *）value inSubitemsAtIndex：（NSUInteger）idx; 
  - （void）removeObjectFromSubitemsAtIndex：（NSUInteger）idx; 
  - （void）insertSubitems：（NSArray *）value atIndexes：（NSIndexSet *）indexes; 
  - （void）removeSubitemsAtIndexes：（NSIndexSet *）indexes; 
  - （void）replaceObjectInSubitemsAtIndex：（NSUInteger）idx withObject：（SubItem *）value; 
  - （void）replaceSubitemsAtIndexes：（NSIndexSet *）indexes withSubitems：（NSArray *）values; 
  - （void）addSubitemsObject：（SubItem *）value; 
  - （void）removeSubitemsObject：（SubItem *）value; 
  - （void）addSubitems：（NSOrderedSet *）values; 
  - （void）removeSubitems：（NSOrderedSet *）values; 
 
 @end 
  

这里是<自动生成的 Item.m ：

  #importItem.h
 #importSubItem.h
 
 @implementation项目
 
 @dynamic名称; 
 @dynamic subitems; 
 
 @end 
  

正如你所看到的， Item 提供了一个名为 addSubitemsObject：的方法。不幸的是，当试图以这种方式使用它：

  Item * item = [NSEntityDescription insertNewObjectForEntityForName：@IteminManagedObjectContext：self .managedObjectContext]; 
 item.name = @FirstItem; 
 
 SubItem * subItem = [NSEntityDescription insertNewObjectForEntityForName：@SubIteminManagedObjectContext：self.managedObjectContext]; 
 
 [item addSubitemsObject：subItem]; 
  

出现此错误：

  2011-09-12 10：28：45.236测试[2002：707] ***  -  [NSSet intersectsSet：]：set参数不是NSSet 
  
 
 
 
您能帮我吗？

从我的错误报告，今天（2016年8月1日）只有1787天后，苹果给我写了这个：请验证这个问题与最新的iOS 10测试版本和更新您的错误报告在bugreport.apple.com与您的结果。。让我们希望这是正确的时间：）
解决方案
我将您的设置与您的数据模型和我自己的名称。我在两种情况下都有相同的错误。 
 
 
 
看起来像是Apple自动生成的代码中的一个错误。 
 
On my Lion app, I have this data model:



The relationship subitems inside Item is ordered.

Xcode 4.1 (build 4B110) has created for me the file Item.h, Item.m, SubItem.h and SubItem.h.

Here is the content (autogenerated) of Item.h:
#import <Foundation/Foundation.h>

#import <CoreData/CoreData.h>

@class SubItem;

@interface Item : NSManagedObject {
@private
}

@property (nonatomic, retain) NSString * name;
@property (nonatomic, retain) NSOrderedSet *subitems;
@end

@interface Item (CoreDataGeneratedAccessors)

- (void)insertObject:(SubItem *)value inSubitemsAtIndex:(NSUInteger)idx;
- (void)removeObjectFromSubitemsAtIndex:(NSUInteger)idx;
- (void)insertSubitems:(NSArray *)value atIndexes:(NSIndexSet *)indexes;
- (void)removeSubitemsAtIndexes:(NSIndexSet *)indexes;
- (void)replaceObjectInSubitemsAtIndex:(NSUInteger)idx withObject:(SubItem *)value;
- (void)replaceSubitemsAtIndexes:(NSIndexSet *)indexes withSubitems:(NSArray *)values;
- (void)addSubitemsObject:(SubItem *)value;
- (void)removeSubitemsObject:(SubItem *)value;
- (void)addSubitems:(NSOrderedSet *)values;
- (void)removeSubitems:(NSOrderedSet *)values;

@end
And here is the content (autogenerated) of Item.m:
#import "Item.h"
#import "SubItem.h"

@implementation Item

@dynamic name;
@dynamic subitems;

@end
As you can see, the class Item offers a method called addSubitemsObject:. Unfortunately, when trying to use it in this way:
Item *item = [NSEntityDescription insertNewObjectForEntityForName:@"Item" inManagedObjectContext:self.managedObjectContext];
item.name = @"FirstItem";

SubItem *subItem = [NSEntityDescription insertNewObjectForEntityForName:@"SubItem" inManagedObjectContext:self.managedObjectContext];

[item addSubitemsObject:subItem];
this error appear:
2011-09-12 10:28:45.236 Test[2002:707] *** -[NSSet intersectsSet:]: set argument is not an NSSet
Can you help me?

Update:

After just 1,787 days from my bug report, today (August 1, 2016) Apple wrote me this: "Please verify this issue with the latest iOS 10 beta build and update your bug report at bugreport.apple.com with your results.". Let's hope this is the right time :)
解决方案
I reproduced your setup both with your data model and one of my own with different names. I got the same error in both cases. 

Looks like a bug in Apple's autogenerated code.
