XCODE auto save code when build and run?

问题:

How to tell Xcode to save the source code automatically without prompting, each time I hit on the build and run?

回答1:

1. Xcode preferences
2. Pick 'Building' tab
3. Lower right corner "For unsaved files:" pick "Always save".

回答2:

Xcode Preferences → Building → Build Options → For Unsaved Files → Always Save?

it seems this is the default behaviour in the current xcode 5. hopefully it will return so we can turn it OFF and dont have this painfully slow rebuild.
