backgrounding

When a foreground app gets backgrounded (e.g. Home button gets pressed), how can I change elements on the topmost view controller prior to when iOS takes a snapshot of it and starts the animation to show the next screen? I ask because I'm writing an app requiring HIPAA compliance, and I am concerned that the snapshot that the OS takes in order to do this animation sometimes contains sensitive data which should not be visible even for a split second when the app gets foregrounded later. I'm aware that view controllers have lifecycle methods such as viewWillDisappear which might be usable, but I

I want to write a program that can be run as a backgrounded task (i.e. my-thing & ), and that will beautifully provide relevant output when necessary. However, with background tasks that print to the terminal, there's always this annoying little progression: bash-3.2$ my-thing & ▏ bash-3.2$ my-thing & bash-3.2$ -- Hello from my-thing! -- now let me start doing what I do best ... ▏ … notice that we now have no prompt before the cursor, not to mention that there's an ugly erraneous prompt where my program spat out output while a prompt had already been printed. Thus, I want three things, only

I've been pouring over all documentation regarding background states and permissions for playing audio in iOS and I can't figure out how a particular app is able to seemingly wake itself at a specific time in the future and play non-bundled sounds. I'm looking into the issue because I'd like to add this functionality (like many others I've seen) to an app I'm building. The app in question is "Alarmy" -- formerly "Sleep if you can." It's an alarm clock. Unlike most other alarm clocks in the app store, it is able to play an iTunes song as an alarm sound without being in the foreground at all. It

I have a script that checks something on my PC every 5 minutes and I don't want Python to show on my task tray. I use Windows as my operating system. Is there any way to make Python run in the background and force it to not show in my task tray? Look for Schedule Tasks in the control panel. If you run a console script using pythonw.exe , it will neither display a window nor appear in the task bar. For example, I use the following command to launch ntlmaps on startup: C:\BenBlank\Python2.6\pythonw.exe scripts/ntlmaps Be aware, however, that there is no way to interact with the script, nor to
