JSOn解析数据显示iphone中相同对象的不同值

当我输入NSLog affecteddate值时，它显示正确，但当我将其存储在var中时，它给出错误的值

   SBJsonParser *parser= [[SBJsonParser alloc] init];

NSString *url = [NSString stringWithFormat:@"http://www.krsconnect.no/community/api.html?method=bareListEventsByCategory&appid=620&category-selected=%@&counties-selected=Vest-Agder,Aust-Agder&range=0-10", test];

NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:url]];




NSData *response = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *json_string = [[NSString alloc] initWithData:response encoding:NSUTF8StringEncoding];
NSDictionary *object = [parser objectWithString:json_string error:nil];
NSArray *results = [parser objectWithString:json_string error:nil];
appDelegate.books1 = [[NSMutableArray alloc] init];
appDelegate.dates =[[NSMutableArray alloc]init];
appDelegate.books2=[[NSMutableArray alloc]init];
appDelegate.books3=[[NSMutableArray alloc]init];
appDelegate.books4=[[NSMutableArray alloc]init];
appDelegate.books5=[[NSMutableArray alloc]init];
appDelegate.books6=[[NSMutableArray alloc]init];
appDelegate.books7=[[NSMutableArray alloc]init];
appDelegate.books8=[[NSMutableArray alloc]init];
appDelegate.books9=[[NSMutableArray alloc]init];
appDelegate.books10=[[NSMutableArray alloc]init];
NSArray *activitiesArray;

mycount=[results count];
for (int j=0;j<[results count]; j++) {

    NSDictionary *dictOne = [results objectAtIndex:j];
    NSLog(@"%@ - %@", [dictOne objectForKey:@"date"]);
    Date  *aDate = [[Date alloc] initWithDictionary:[results objectAtIndex:j]];
    [appDelegate.dates addObject:aDate];
    [aDate release];
    activitiesArray = [dictOne objectForKey:@"events"];




     for (int i=0; i<[activitiesArray count]; i++) {

        int testcount =[activitiesArray count];
        NSDictionary *dictTwo = [activitiesArray objectAtIndex:i];

        NSDictionary *eventDict=[dictTwo objectForKey:@"event"];



        //  NSLog(@"%@ - %@", [dictOne objectForKey:@"date"]);
        //  NSLog(@"%@ - %@", [dictTwo objectForKey:@"affectedDate"]);
        //  NSLog(@"%@ - %@", [eventDict objectForKey:@"location"]);



        NSInteger*date=[dictTwo objectForKey:@"affectedDate"];

        NSInteger*affecteddate=[dictTwo objectForKey:@"affectedDate"];

        NSLog(@"%@ - %@", [dictTwo objectForKey:@"affectedDate"]);

        NSString*appId =[eventDict objectForKey:@"appId"];
        NSLog(@"%@ - %@", [eventDict objectForKey:@"eventId"]);

        NSInteger*eventId=[eventDict objectForKey:@"eventId"];

        int next=[affecteddate intValue];
        int next_int = [eventId intValue];



        NSString*location=[eventDict objectForKey:@"location"];
        NSString*municipality=[eventDict objectForKey:@"municipality"];
        NSString*title=[eventDict objectForKey:@"title"];




    Book1 *aBook=[[Book1 alloc] initWithDate:date affecteddate:affecteddate   eventId:eventId location:location municipality:municipality title:title];

首先，你有：

NSInteger*affecteddate=[dictTwo objectForKey:@"affectedDate"];

后来

intValue

对整数无效

您可能想要：

NSNumber *date = [dictTwo objectForKey:@"affectedDate"];

NSNumber *affecteddate = [dictTwo objectForKey:@"affectedDate"];

可以在book对象中声明这样的值来指定此值

   NSNumber *affecteddate;
  @propert(nonatomic,retain)

这里什么是“正确的”，什么是“错误的”？您认为“正确”的NSLog输出是什么？您认为“错误”的ivar包含什么您不需要一页代码来演示这一点。我从JSON数据中获取这些数据，我已签入数据NSLog out是正确的，我还发布了JSON解析代码，这给出的worng值与我在eventId中使用的值不符，如上所示，它的工作特性我发布了Book类代码，那么我如何在那里声明affecteddate[dictTwo objectForKey:@“affectedDate”]返回一个对象，可能是NSInteger*，而不是int。只有对象才能放入字典、数组或其他对象容器类型中。因此，如何声明此对象并从书本访问它们ObjectInteger不是一个对象，而是一个int。NSNumber是一个可以保存数字的对象。

NSNumber *date = [dictTwo objectForKey:@"affectedDate"];

NSNumber *affecteddate = [dictTwo objectForKey:@"affectedDate"];

   NSNumber *affecteddate;
  @propert(nonatomic,retain)
