Questions tagged [nib]

NIB files are similar to XIB files (XCode Interface Builder), with the difference being XIB files are modified during development and NIB files are created during the build process. NIBs store static information about the interface as well as any behavior that has been implemented.

Storyboards have since succeeded NIB/XIB files as the latest UI interface tool.

If you have an IBOutlet, but not a property, is it retained or not?
