如何在iOS中以编程方式重新启动或重新加载iPhone应用程序

Question

I have dowloaded an xml file that contains some update parameters and then I need to reload these parameters and init some views. Easiest way is to apply this configuration on next app boot. Is there any way to reboot iOS application programmatically?

Thank you.

Answer 1

Rebooting the app is a bad idea, I'm pretty sure Apple would reject it. However, You could display a popup telling the user to open a close the app to apply your updated information. But the best way would be just to manually call the methods needed to rebuild your app (Ie the ones that need to use the updated data). If you have to do some extensive rebuilding (ie things that the user would immediately notice) it might be a good idea to add in a "loading" progress bar of sorts.

Answer 3

You can quit and restart an iOS app with a bit of user assistance. Set the app's plist key for application exits on suspend. Create a local notification for your app to trigger a few seconds into the future. Then send Safari a URL. The OS will terminate your app when launching Safari to handle the URL. The URL might be to a web landing page telling the user that a relaunch is in progress. Then the local notification will go off and ask the user to relaunch your app.

However an app should be (re)designed so that there is never a reason to do this.

You can do it only if your device is jailbroken

Put a reboot button in your app and call abort(); . This will crash the app.

Hook the -(void)exitedAbnormally ; from SBApplication and write code to launch your app.

If its not jailbroken, you have no choice

Answer 5

if you develop for jailbroken devices you can use uicache command to clean the springboard cache and reload new apps/icons (available from UIKit package).

for example,

1) if you're under root:

    su mobile -c uicache 1>/dev/null 2>&1

2) if you're under mobile:

    uicache

for reboot you can use reboot command under root and killall SpringBoard for respring
