在我的应用程序中我使用Yahoo Api并获得响应我现在使用JSONModel创建一个json JSONModel类。

中的如果我删除//
并尝试获取NSString
c
,dt
,cd
个对象,则会出现问题我的Past_Match对象变为空。所有3 NSString
都有同样的问题,我无法获得该值。所有其他价值都在增加。我错过了什么?在此先感谢..
答案 0 :(得分:1)
由于响应对象中的可选值可能会发生此错误,请尝试此操作....可能有效
@property (strong, nonatomic)NSString<Optional> *c;
@property (strong, nonatomic) NSString<Optional> *dt;
@property (strong, nonatomic) NSString<Optional> *cb;
提示:请将所有属性设为可选
