#import <Foundation/Foundation.h>

@interface Car : NSObject

@property (nonatomic, copy)NSString *icon;

@property (nonatomic, copy)NSString *name;

//初始化+便利构造器初始化
- (instancetype)initWithDic:(NSDictionary *)dict;

+ (Car *)carWithDic: (NSDictionary *)dict;

//自定义返回数组方法，此数组即为存放 “Car”这个model的数组，在MVC - V or C种可以用NSArray * arr = 【Car cars】调用, arr即为VC种数据源

+ (NSArray *)cars;

@end

#import "Car.h"

@implementation Car

- (instancetype)initWithDic:(NSDictionary *)dict {
    self = [super init];
    if (self) {
        [self setValuesForKeysWithDictionary:dict];
    }
    return self;
}
