Restkit映射错误

Question

我是restkit的新手,我在我的应用程序中使用它以及核心数据.我非常惊讶restkit与核心数据一起工作的方式.简直太棒了.但是在解析我的一个Web服务时,我遇到了一个重大问题.该应用程序继续崩溃,无法映射响应中的值.以下是我的回应 -

[{"id":10,"created":"2012-10-06 13:32:09 +0000","createdBy":null,"functionalCurrency":null,"imageUrl":null,"lat":null ,"lon":null,"maxOccupancy":0,"name":"Patio Dining","posX":0,"posY":0,"reportingCurrency":null,"salesTaxRate1":0,"salesTaxRate2": 0,"salesTaxRate3":0,"salesTaxRate4":0,"timezone":" - 0830","transactionalCurrency":null,"updated":"2012-10-06 13:32:09 +0000","updatedBy" ": 空值}]

我收到以下错误.-

E restkit.object_mapping:RKObjectMappingOperation.m:262将关键路径'locationId'的属性映射到值10时验证失败.错误:无法完成操作.(Cocoa error 1610.) - [__ NSCFNumber length]:无法识别的选择器发送到实例0x774e020

我的位置类声明如下 -

@interface Location : NSManagedObject


@property (nonatomic,strong)NSNumber *locationId;
@property (strong, nonatomic) NSString *created;
@property (nonatomic,strong)  NSString *createdBy;
@property (nonatomic,strong)  NSString *functionalCurrency;
@property (nonatomic,strong)  NSString *imageUrl;
@property (strong, nonatomic) NSString *lat;
@property (strong, nonatomic) NSString *lon;

我将经理初始化如下 -

    RKURL *baseURL = [RKURL URLWithBaseURLString:serverUrl];

            objectManager = [RKObjectManager objectManagerWithBaseURL:baseURL];

            objectManager.client.baseURL = baseURL;

            objectManager.client.requestQueue.showsNetworkActivityIndicatorWhenBusy = YES;
[RKObjectManager setSharedManager:objectManager];

[objectManager loadObjectsAtResourcePath:[NSString stringWithFormat:@"%@", [URL resourcePath]] delegate:self];

当我尝试将locationId设置为NSString时,RKObjectManager根本不匹配'9'之后的任何值.当设置为NSNumber时,它与'2'后的任何值都不匹配.

请帮我.RKManagedObjectMapping也发生了同样的事情,因此没有数据进入我的核心数据文件.

Answer 1

嗯这真是非常尴尬,经过大量的敲击后终于找到了问题所在.核心数据中我的locationId的最大值设置为1.这导致验证错误.
