Question

我的代码

·H

@interface fileHandler : NSObject

@property NSMutableArray *arrCategoryList;
@property NSMutableDictionary *dicCategoryList;
@property NSMutableDictionary *dicAllSubCategoryList;
@property NSMutableDictionary *dicProductList;

+(fileHandler *)getDataHandler;
-(void)categoryStorage:(NSMutableArray *)arrCategory :(NSMutableDictionary *)dicCategory :(NSMutableDictionary *)dicSubCategory;

的.m

static fileHandler *internalInstance=Nil;
static dispatch_once_t internalOnceToken=0;

@implementation fileHandler
-(id)init
{
    self=[super init];
    [self allocateMemory];
    return self;

}

+(fileHandler *)getDataHandler
{

    dispatch_once(&internalOnceToken,^{
        internalInstance = [[fileHandler alloc] init];
        if(internalInstance) {
            NSLog(@"Internal instance created: %@", internalInstance);
        }
    });
    if(internalOnceToken == -1) {
        NSLog(@"Internal instance exists: %@", internalInstance);
    }
    return internalInstance;

}
-(void)allocateMemory
{       NSLog(@"incoming");
        self.arrCategoryList=[[NSMutableArray alloc]init];
        self.dicCategoryList=[[NSMutableDictionary alloc]init];
        self.dicAllSubCategoryList=[[NSMutableDictionary alloc]init];
        self.dicProductList=[[NSMutableDictionary alloc]init];
}
-(void)categoryStorage:(NSMutableArray *)arrCategory :(NSMutableDictionary *)dicCategory :(NSMutableDictionary *)dicSubCategory
{
//        arrCategory =[[NSMutableArray alloc]init];
        self.arrCategoryList=arrCategory;
//       [self.arrCategoryList addObject:arrCategory];
//        NSLog(@"inside data handler file==%@",self.arrCategoryList);
//        dicCategory=[[NSMutableDictionary alloc]init];
        self.dicCategoryList=dicCategory;
//        dicSubCategory=[[NSMutableDictionary alloc]init];
        self.dicAllSubCategoryList=dicSubCategory;

}

这里我创建了静态线程，然后我试图将所有值存储到其他类中提到的数组和字典中，一旦我在这里存储了值，那么我必须访问那些数据到我的app中的任何位置

可能吗？

这是对的吗？另一个类文件的的.m

像这样我试图将值存储在NSobject类数组中。

 for(NSDictionary *DicHoleCategories in ArrCategory)
        {

              NSMutableDictionary *DicAllValues=[[NSMutableDictionary alloc]init];

              [DicAllValues setObject:[[DicHoleCategories objectForKey:@"name"] length]  !=0?[DicHoleCategories objectForKey:@"name"] :@"" forKey:@"name"];

               StrName=[DicHoleCategories objectForKey:@"image"];
              [DicAllValues setObject:[DicHoleCategories objectForKey:@"subcategory"] forKey:@"subcategory"];
              if(StrName!=nil)
              {
                subimages=[NSString stringWithFormat:LocalImage"%@",StrName];
                [DicAllValues setObject:subimages forKey:@"image"];
                [arrImages addObject:[DicAllValues objectForKey:@"image"]];
              }
              [ArrName addObject:DicAllValues];
              [arrSubCategory addObject:[DicAllValues objectForKey:@"subcategory"]];

            [dicSubCategory setObject:[DicAllValues objectForKey:@"subcategory"] forKey:@"subcategory"];
            [dicAllValues setObject:dicAllValues forKey:@"hole"];
        }
        [file categoryStorage:ArrCategory :dicAllValues :dicSubCategory];

输出：

Collection <__NSArrayM: 0x7f8c33c7b220> was mutated while being enumerated.'

如何存储json值一次到移动应用程序删除的生命周期？
