QuickLook插件显示图像和一些信息

Question

我正在编写一个QuickLook插件，我想知道如何同时显示图像和有关该图像的一些信息，类似于http://www.code-line.com/software/sneakpeekphoto/ 。

Answer 1

There is only one way to do so: Convert your content to an already supported one. This means either PDF or HTML. There are two options you have:

1. For static information you create a simple PDF preview by rendering a view into a PDF. (Use -dataWithPDFInsideRect: method of NSView )
2. For dynamic information create a HTML page with links and so on. QuickLook will then show it. (I think this is also the way your example does it.)

We have not found a way to create complex previews on ur own and had to stick to one of the methods, too. Keynote and Pages do the same -- they convert their presentations to multi-page PDF previews...
