backgrounding

问题 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

问题 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? 回答1: Look for Schedule Tasks in the control panel. 回答2: 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

问题 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

问题 I really can't figure this out. When I click a link to open Safari from within my app, browse through the webpage, then return to my app, I can open and browse two tabBarItems in my UITabBar . But, when I try to select the one atIndex: 0 , I get an EXEC_BAD_ACCESS and the following :(. Can anyone help me figure out how to make this not happen? I currently don't have any code that executes in will or didEnterBackground or Foreground . None. So the problem must be in the UIViewController for

问题 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
