My app produces a list of images (NSData format), and I'd like the app
Preview to display the image when the user double-clicks on an image
in my app.
Currently I use NSPerformService as shown below, which works, but
Preview always asks to save the file when you close its window. I've
seen other apps where you double-click an image and Preview opens a
window with a title something like "Preview of ...." and it doesn't
try to save the image when you close the window.
To send an image to Preview using NSPerformService:
NSData *data; /* assume exists */
NSPasteboard *pb = [NSPasteboard pasteboardWithUniqueName];
[pb declareTypes:[NSArray arrayWithObject:NSTIFFPboardType] owner:nil];
[pb setData:data forType:NSTIFFPboardType];
NSPerformService( @"Preview/Open images", pb );
It works, but is there a better way to send image data to Preview?
Thanks in advance!
