delegates - JSONModel + 复杂对象

Question

我对这个库和我的对象有一些问题，我有 3 种对象：页面、小部件、画廊

page:
int
string
dictionary of widget

widget:
int
string 
dictionary gallery

gallery
int
string
array page

我创建了所有协议，所以我创建了类似的东西：

        page:
        import widget
        int
        string
        dict<Widget>

        widget
        import gallery
        int
        string
        Gallery
        dict<Gallery>

        Gallery
        import page
        int
        string
        array<Page>

在我创建委托和所有这些之后，我得到“未知类型”错误并且找不到协议......错误在哪里？

Answer 1

需要定义协议并导入头文件

//Page.h
@protocol Page
@end

@class Widget;

@interface Page : JSONModel

@property (nonatomic, assign) NSInteger pageID;
@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) Widget *widget;

//Widget.h
@class Gallery;

@interface Widget : JSONModel

@property (nonatomic, assign) NSInteger widgetID;
@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) Gallery *gallery;

//Gallery.h
#import "Page.h"

@interface Gallery : JSONModel

@property (nonatomic, assign) NSInteger galleryID;
@property (nonatomic, strong) NSString *name;
@property (nonatomic, strong) NSArray<Page>* pages;
