标题: ios - "unrecognized selector sent to instance"属性 setter
我有一个继承自 UILocalNotification 的自定义类，它有一个 Store 对象属性(继承自 NSObject 的类):
customLocalNotification.h:
@property (strong,nonatomic) 存储 *store;
但是当我尝试像这样在 viewController 中设置“Store”对象时:
customLocalNotification *notification=[[customLocalNotification alloc] init];
notification.store=store; //Crashes here
编辑:我将使用 userInfo 字典来保存我的 Store 对象，但是当我尝试这样做时，它会因此错误而崩溃留言:

Best Answer-推荐答案
UILocalNotifications 旨在包含一些轻量级数据。也就是说，userInfo 可以包含 property list encodable仅限项目。而且我要补充一点，整个事情并不是为了扔重物而设计的，而只是传递一些上下文信息，当通知到达时您需要处理这些信息(即一些标识符、数字等)。
