iOS applications may crash (suddenly quit and return to the home screen) under a variety of circumstances. Although the exact cause of these crashes can prove elusive, there are a few simple, effective fixes that can prevent future unexpected quits.
Delete then reinstall app(s). This simple fix works in a majority of app-crash cases, as it deletes potentially problematic data associated with apps. Follow these steps:
- Tap and hold an app icon until the icons begin to wiggle, then tap the”x” in the corner of the application you want to delete.
- Choose “delete” then press the Home button.
- Redownload the app, either by syncing with your computer or searching and downloading it again from the App Store (you won’t be charged again).
Unauthorize then reauthorize. On your computer, open iTunes then go to the “Store” menu and select “Deauthorize This Computer.” After the account is deauthorized, again go to the “Store” menu and this time choose “Authorize This Computer.” Now re-sync your iOS device.
The 4 Rs. Failing the above, run through the 4 Rs of iOS troubleshooting: reboot, reset settings, restore, and reseat.
App-specific fixes. Some iOS apps have specific crash fixes. See these articles:
