changing a picker to table view OR having multiple table views on the same view

- by Brodie4598

Hello - My iPad app was rejected due to my use of a picker. The picker was used to control a table view. In my view, a picker was displaying a series of items and when one of those items was selected, it used that selection to populate a table with data. (hopefully that makes sense). Now I need to do this without the picker so I need to have the data that was in the picker be represented in a table view. My question, is how do I have multiple tableViews in the same view? I'm guessing I need to have some kind of if statement in the tableview delegate methods, but I'm not quite sure what the if statement needs to be. Or maybe i'm thinking of this the totally wrong way thanks

iPad device orientation is null?

- by Brodie4598

([UIDevice currentDevice].orientation); using the above code in my app, all i get is 0 (unknown) is there something thats going wrong here? Seems pretty straightforward edit: more research led me to the problem with using device orientation early in the app, which I am doing. However when I instead use interfaceOrientation, it always returns 1 (portrait)

iphone view controller class - how to

- by Brodie4598

Hello - I need to create my own UIView class and it is not something I have had to do. I created the class, then laid out the small view in IB (it's just a few labels that i will later need to add data to ). but now im stuck on how to actually put an instance of it in my main view. Can someone point me in the direction of a good tutorial? The closest thing I have done to this is creating a custom tableViewCell. DataTagViewController *dataTag = [[DataTagViewController alloc]init]; [theMap addSubView: dataTag];

Retaining objects in game iphone

- by Brodie4598

Hello - I am trying to create a game and have run into what is probably a pretty easy problem to solve. As the player goes through the game, many objects (Vehicle) will be added and removed. The Vehicles get added to an array called currentVehiclesMutableArray. My problem is I cant figure out how to retain a Vehicle so that it remains in the array until I am finished with it.
