Is there any reason adding a UIPicker to a view might somehow rob a programatically created button of its functionality? I initially instantiated a UIButton to take me to a different view, and all was well and fine. Then I went ahead and added a UIPicker to the same view with the purpose of selecting a few key fields which could then b...

In the method itself, how do I determine what type of object touches actually contain? In this case, it contains a set of UITouch. But I knew that from reading some tutorials online. In ge...
I'd like some assistance to properly remove subviews from a scrollview, to reduce memory usage. Every time the user scrolls, I ask to grab page, page -1 and page+1 to get the views loaded in the scrollview.

I want to introduce the ability for the my core-data app to download a NEW sqlite file and update its stored data. Note the data model is not changing. At first I am not worrying about user changes to the stored data, and simply want to overwrite it. I am finding the only way the stored data is updating is to change the name of the sq...
