I am looking for a way (public or otherwise) to get an NSView, NSImage, CGImageRef, etc that shows the QuickLook preview for a file. Essentially the equivalent of QLThumbnailImageCreate() but for the preview. The public APIs I can find do not support this. They allow the creation of a thumbnail image or a QLPreviewPanel. The panel does in fact display the quick look preview, but I cannot get access to the preview's appearance to embed it in other views, nor can I display multiple previews at once.

My quick look generator used to work properly but is now broken. Is it a bug or am I doing something wrong? Here’s my code: OSStatus GeneratePreviewForURL(void *thisInterface, QLPreviewRequestRef preview, CFURLRef url, CFStringRef contentTypeUTI, CFDictionaryRef options) { NSDictionary * myDoc = [NSDictionary dictionaryWithContentsOfURL:(NSURL *)url]; if (myDoc) { NSData * pngData = [myDoc valueForKey:@"pngPreview"]; if (pngData) { QLPreviewRequestSetDataRepresentation(preview,(__bridge CFDataRef)pngData, kUTTypeImage,NULL); } } } My doc is a normal plist with a png preview stored as data in

Xcode 5 has a great new feature where you can hover over a variable name and get a visual representation of a UIColor, UIImage, or even UIBezierPath.

I would love to add this to a bunch of my model objects to help me debug. Anyone know whether this is a real thing yet, or even if they hinted at it in a future release? Unfortunately, Apple refers to this feature as "Quick Look" and since they have

Rather i didn't find it anywhere. I want to run the plugin in debug mode and want to hit the breakpoints so that i can figure out where the plugin crashes on different files. It would be great if someone share his knowledge. Thanks in advance. Mikhail Grebionkin You can use brake points and NSLog function for debugging QL plugin. But first you need to configure environment. Select your project on Project
