I am about to embark on developing a mobile application for both the iPhone and the Android based phone. I have most of my gui mock ups written down on a white board and some in my head.

I have some animations happening upon fine acceleration detections. But when the user sits in a car or is walking it may get annoying. Basically, all that stuff has to be disabled automatically as soon as there is too much vibration or shaking. Conceptually, I think that it's very hard to filter those vibrations out , since the "vibrati...

I have a UIScrollView where a lot of objects appear (UIImageView's) during scrolling. However, when the user is scrolling, I want to fire messages to all these objects, in order to tell them that they shall not do anything stupid.

I am implementing a sound effect that plays while a user is dragging a UISlider. In a previous question, I used AudioServicesPlaySystemSound() but that type of sound can't be halted. I need the sound to halt when the user is not actively dragging the slider but has not released it. Now I am creating a sound using an AVAudioPlayer objec...
I have a small iPhone app that stores a list of objects. The user can add and remove objects, but this list will remain fairly small (most users would have 10-30 objects). NSUserDefaults seems much easier to work with, but will sqlite3 be faster? With only 30 "records" will there be any noticeable difference? ...
