懒加载

在get中加载，且只加载一次

- (NSArray *)shops

{

if (_shops == nil) {

NSString *file = [[NSBundle mainBundle] pathForResource:@"shops" ofType:@"plist"];

self.shops = [NSArray arrayWithContentsOfFile:file];

//        _shops = [NSArray arrayWithContentsOfFile:file];

//        [self setShops:[NSArray arrayWithContentsOfFile:file]];

}

return _shops;

}

模型

根据具体业务数据来确定的数据模型，可以替代NSDictionary

自定义代码片段

用<#param#>来设置变量

重写构造方法

- (instancetype)initWithDict:(NSDictionary *)dict

{

if (self = [super init]) {

self.name = dict[@"name"];

self.icon = dict[@"icon"];

}

return self;

}

+ (instancetype)shopWithDict:(NSDictionary *)dict

{

return [[self alloc] initWithDict:dict];

}
