PDFThumbnailView broken on macOS 10.12

Same here. Couldn't find any way to make it respond to selecting and dragging again. Will probably just ditch it altogether and roll out my own based on a collection view.

Did you find a solution for the selection problem or can you share your collection view? Thank you!

I didn't get around to writing my own PDFThumbnailView replacement yet. I want to check wheter 10.12.2 update solves any of the PDFKit problems before I decide how to approach this and the many other PDFKit issues.

PDFThumbnailView continues to be broken in macOS 10.12.3 beta 1.

Also filed a bug report: #29739427.

😟

I cannot wait for a fix in 10.3. I need also a fallback for 10.12.1 an 10.12.2. I wrote my own PDFThumbnailView implementation which should work as expected.

Search on Github for HSPDFThumbnailView.

I hope it will also work for your projects.

Thanks for your code :-) I've just added a check on selectionIndex to prevent a potential crash

- (void)observeValueForKeyPath:(NSString *)keyPath

ofObject:(id)object

change:(NSDictionary *)change

context:(void *)context

{

if ([keyPath isEqualToString:@"selectedObjects"])

{

if ( self.arrayController.selectionIndex != NSNotFound )

[self.PDFView goToPage:[self.PDFView.document pageAtIndex:self.arrayController.selectionIndex]];

}

else if ([keyPath isEqualToString:@"document"])

{

[self willChangeValueForKey:@"items"];

[self.items removeAllObjects];

for (int i=0; i < self.PDFView.document.pageCount; i++)

{

NSMutableDictionary *newDict = [NSMutableDictionary new];

[newDict setObject:[NSString stringWithFormat:@"%d", (i + 1)] forKey:@"label"];

[newDict setObject:[self.PDFView.document pageAtIndex:i] forKey:@"page"];

[self.items addObject:newDict];

}

[self didChangeValueForKey:@"items"];

}

}
