I want to make simple iOS app. From the list - 300 persons you select one person based on his name ( names will be different ) and then you see 4 different atributes of this person. I see it as UITable view with one Label and 4 cells with attributes. What is common way to keep all this data - names and attributes? It will be around 1200 records. Should I use NSArray , or NSDictionary ? Name could be the key to corresponding attributes. Maybe someone could tip on some tutorial? Many thanks!
