Is there a way to use the WebKit web inspector from a Cocoa WebView object?

cocoa, webkit

Solution

Set `WebKitDeveloperExtras` to `YES` in your default user defaults when you send `-[NSUserDefaults registerDefaults:]`. This applies app-wide, of course.

Remember that the user can change it to `NO`, so don't assume that it's `YES`—if it ever matters (e.g., when customizing the contextual menu), always check.

Warning: This preference doesn't necessarily only enable the Element Inspector. Apple may extend it in the future to also control, say, a Debug menu in your menu bar. You may find this an unacceptable risk.
