Bridger, Which version of Interface Builder are you using? Do you have multiple installations of the developer tools on your system? -Joey On Jan 29, 2009, at 10:14 AM, Bridger Maxwell wrote: Hey, I created a custom Interface Builder plug-in, which seemed to work great until I actually

re: Core data storage of objects whose class is loaded from a bundle

I am working on an app in which plugin subclasses are loaded from bundles at launch time (didFinishLaunching in app delegate). The base plugin class is specified in a framework against which the main app is linked. I can create instances of these dynamically loaded subclasses, and assign them as

It turns out the error is completely different from what I thought it was (isn't it always?). It turns out Xcode was omitting part of the output from IBTool. When I tried to compile my xib from Terminal, I got this error: Description: ibtool encountered an error while loading the ibplugin from /Us

Looks like your plug-in is being running as a tool without a connection to the window server. On 01/29/2009 3:54 PM, "Bridger Maxwell" wrote: > It turns out the error is completely different from what I thought it was > (isn't it always?). It turns out Xcode was omitting part of the output from

Re: Interface Builder Plugin Dependency

Bridger, Because ibtool runs from the command line, it is executed without a connection to the window server so it can be run remotely in non- graphical login sessions. This environment might exist, for example, on a build server with nobody logged in at the console. You'll need to find an

Is the NSData used to create a NSImage copied or retained?

This is a simple question, that I can not find in the documentation. When a programmer uses the NSImage's initWithData: method to create an image, the call is passed an NSData object. This is usually a data representation of a JPEG, GIF or other graphic file format (usually read from a file

Re: Interface Builder Plugin Dependency

Hey Bridger - Does your plug-in and framework really need to create and crop an image while being unarchived and re-archived by ibtool? Perhaps you could retool your class so that the work happens lazily, and doesn't occur durring XIB compilation. As Joey said, ibtool to runs with no wind
