设计模式

处理Model ： 推荐采用适配器模式

目标接口

@protocol BusinessCardAdapterProtocol <NSObject>

- (NSString *)name;

- (UIColor *)lineColor;

- (NSString *)phoneNumber;

@end

//目标对象

/**
 *  名字
 */
@property (nonatomic, strong) NSString *name;

/**
 *  线条颜色
 */
@property (nonatomic, strong) UIColor  *lineColor;

/**
 *  电话号码
 */
@property (nonatomic, strong) NSString *phoneNumber;

//输入方使用适配器

BusinessCardAdapter *modelAdapter = [[CardAdapter alloc] initWithData:model]2;

//适配器初始化函数
- (instancetype)initWithData:(id)data {
    
    self = [super init];
    if (self) {
        
        self.data = data;
    }
    
    return self;
}

使用方使用适配器

- (void)loadData:(id <BusinessCardAdapterProtocol>)data {
    self.name        = [data name];
    self.lineColor   = [data lineColor];
    self.phoneNumber = [data phoneNumber];
}
