iOS之OC随笔-Model数据类型

if (_dataArray == nil) {
// 初始化数组dataArray

// 1.获得plist的全路径
NSString *path = [[NSBundle mainBundle] pathForResource:@"app.plist" ofType:nil];

// 2.加载数组
NSArray *dictArray = [NSArray arrayWithContentsOfFile:path];

// 3.将dictArray里面的所有字典转成模型对象,放到新的数组中
NSMutableArray *modelArray = [NSMutableArray array];

for (NSDictionary *dict in dictArray) {
// 3.1.创建模型对象
//Model *model = [[Model alloc] initWithDict:dict];下面代替
Model *model = [Model modelWithDict:dict];

// 3.2.添加模型对象到数组中
[modelArray addObject:model];
}

// 4.赋值
_dataArray = modelArray;
}
return _dataArray;

/** 名称 */
@property (nonatomic, copy) NSString *name;
/**  图标*/
@property (nonatomic, copy) NSString *icon;
/**通过字典来初始化模型对象
- (instancetype)initWithDict:(NSDictionary *)dict;

//或者自己创建类方法
+ (instancetype)modelWithDict:(NSDictionary *)dict;

- (instancetype)initWithDict:(NSDictionary *)dict{
if (self = [super init]) {
self.name = dict[@"name"];
self.icon = dict[@"icon"];
}
return self;
}

//或者
+ (instancetype)modelWithDict:(NSDictionary *)dict{
//    Model *model =[[Model alloc]initWithDict:dict];
//    return model;
return [[self alloc] initWithDict:dict];
}
