@interface ModelClass : SCObject
@property (strong, nonatomic) NSString *scObjectID;
@property (strong, nonatomic) NSString *title;
@property (strong, nonatomic) NSString *videoUrlHLS;
@property (strong, nonatomic) NSString *fileUrlDirect;
@implementation ModelClass
+ (NSDictionary *)JSONKeyPathsByPropertyKey
{
return @{ Key(ModelClass, scObjectID) : @"MediaId",
Key(ModelClass, title) : @"Title",
Key(ModelClass, videoUrlHLS) : @"VideoUrlAppleHLS",
Key(ModelClass, fileUrlDirect) : @"FileUrlS3Direct"
}
fileUrlDirect属性是新属性,更新了JSONKeyPathsByPropertyKey以将json属性转换为模型属性
@property (strong, nonatomic) NSString *fileUrlDirect;
Key(ModelClass, fileUrlDirect) : @"FileUrlS3Direct"
当我跑步时
[MTLManagedObjectAdapter managedObjectFromModel:instanceOfModelClass insertingIntoContext:context error:error];
我收到了
[0] (null) @"NSLocalizedDescription" : @"Could not serialize managed object"
[1] (null) @"NSLocalizedFailureReason" : @"No property by name \"fileUrlDirect\" exists on the entity."
我已经调试并确认instanceOfModelClass具有新属性但我无法弄清楚为什么我收到此错误
我是ios开发的新手,我猜这里还有更多工作要点,但我不知道是什么
答案 0 :(得分:0)
您在核心数据实体中缺少名为fileUrlDirect
的属性,而您正在将instanceOfModelClass
映射到该属性。
