Dictionary-to-model, model-to-dictionary, convert an array in a class directly into a model

/**

* Model classes that need to be converted in an array

*

* The key in the @return dictionary is the array property name, and value is the class that holds the model in the array

*/

-(Nsdictionary *) Objectclassinarray;

Usage examples:

@property (Nonatomic,strong) Nsarray *pic_urls;

-(Nsdictionary *)objectclassinarray{

return @{@ "Pic_urls": [Statusphoto class]};

}

Nsarray *statusarray = [Statusmodel objectarraywithkeyvaluesarray:json[@ "statuses"]];

With this method, the elements inside the array pic_urls will all be converted to the Statusphoto type.
