关于猿题库MVVM without binding with d

先借用一张图，大致的逻辑如下：

新建项目，结构如下：

各个类的代码如下：

DYBaseDataVC

#import <Foundation/Foundation.h>
typedef void (^DYDataResponseBlock)(id response,NSError *error);
@interface DYBaseDataVC : NSObject

@end

#import "DYBaseDataVC.h"

@implementation DYBaseDataVC

@end

HomeModel

#import <Foundation/Foundation.h>

@interface HomeModel : NSObject
@property (nonatomic,strong)NSString *name;
@property (nonatomic,assign)NSInteger age;
@property (nonatomic,strong)NSString *address;
@end

#import "HomeModel.h"

@implementation HomeModel

@end

ViewController

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController


@end

#import "ViewController.h"
#import "CustomView.h"
#import "ViewControllerDatacontroller.h"
#import "HomeViewModel.h"
@interface ViewController ()
@property (nonatomic,strong) CustomView *userInfoView;
@property (nonatomic,strong) ViewControllerDatacontroller *dataController;

@end

@implementation ViewController

ViewControllerDatacontroller

    model.age = 20;
    model.name = @"张三";
    if (block) {
        block(model,nil);
    }
}
@end

CustomView

#import <UIKit/UIKit.h>
#import "HomeViewModel.h"
@interface CustomView : UIView
//根据viewModel组装的数据，显示ui
- (void)bindData:(HomeViewModel *)model;
@end

#import "CustomView.h"

    }

@end

HomeViewModel

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import "HomeModel.h"

@interface HomeViewModel : NSObject
//model
@property (nonatomic,strong)HomeModel *model;
//背景颜色
@property (nonatomic,strong)UIColor *bgColor;
//字体大小
@property (nonatomic,strong)UIFont *titleFont;

+ (HomeViewModel *)viewModelWith:(HomeModel *)homeModel;
@end

#import "HomeViewModel.h"

@implementation HomeViewModel
+ (HomeViewModel *)viewModelWith:(HomeModel *)homeModel{
    //组装view需要的数据
    HomeViewModel *model = [[HomeViewModel alloc] init];
    model.model = homeModel;
    model.bgColor = [UIColor lightGrayColor];
    model.titleFont = [UIFont systemFontOfSize:10];
    return model;
}
@end

功能很简单，只是实现了获取数据后，UI的刷新展示。不知道理解的是否有问题，有问题欢迎提出。
