How can I assign element of array to my property?

Question

I have an array that stores models:

@property (nonatomic, strong) NSMutableArray *models;

and other properties of type "Model",like:

@property (nonatomic, strong) Model *mainModel;
@property (nonatomic, strong) Model *adModel;
@property (nonatomic, strong) Model *tradeModel;
@property (nonatomic, strong) Model *tradeOpenModel;

I want to assign every element of models to property, how can I do this by runtime instead of self.mainModel = models[0];

just an example, I want to get the model by property instead of models[0]. — XM Zhang

Did you mean [models objectAtIndex:0]? You should explain you question more clearly. — trungduc

If you are able to differentiate model through a property then you don't need these extra properties. Just filter your array whenever you need a specific model by that property. — Muhammad Zohaib Ehsan

Instead of NSMutableArray use a custom model (lets say allModelList) that will contain the other four models i.e mainModel,adModel,tradeModel,tradeOpenModel as properties. So while parsing you can set these properties and then easily access by

allModelList.mainModel
allModelList.adModel
allModelList.tradeModel
allModelList.tradeOpenModel

Hope it helps you.
