因为原有的在很多地方都有调用，不想动，后面又想添加，代码如下：
- (instancetype)initWithFastShopModel:(FastShopModel *)fastShopModel
{
self = [super init];
if (self){
self.fastShopModel = fastShopModel;
}
return self;
}
- (instancetype)initWithMyShopMutableDic:(NSMutableDictionary *)myShopMutableDic{
FastShopModel *fastShopModel = [FastShopModel new];
fastShopModel.code = [myShopMutableDic validStringValueForKey:@"code"];
fastShopModel.company = [myShopMutableDic validStringValueForKey:@"company"];
fastShopModel.dbname = [myShopMutableDic validStringValueForKey:@"dbname"];
QbuyDetailVC *qbuyDetailVC = [self initWithFastShopModel:fastShopModel];
return qbuyDetailVC;
}
拿原有的UIViewController返回进行修改，虽然看起来是两个init，其实是一个init
