Currently we miss calling `-[super touches*]` on `_ASDisplayView` touch events. We delegate handling to the node which then forwards all touch events to the *superview*, skipping the current view. This seems to have some side effects with `UITableView` and it's cells/content views.
fixes#188
ASRangeController previously enqueued display of individual nodes by
adding their views to the hierarchy, wrapping each `-addSubview:` call
in an explicit CATransaction to force displays to occur in order. This
hack is no longer necessary -- kill it.
ASDisplayNodes now have an overidable method -placeholderImage that lets you provide a custom UIImage to display while a node is displaying asyncronously. The default implementation of this method returns nil and thus does nothing. A provided example project also demonstrates using the placeholder API.
These weren't correctly handling teardown: nilling the `asyncDelegate`
created a new selector-forwarding NSProxy that crashed and burned
because there was nowhere to forward to. Nil everything correctly.
Tentatively fixes#121.
Postpone manual display until a future release when it can be called on any thread. Provide the current node manual display logic as a category on ASDisplayNode only available for ASRangeController. Deprecate -displayImmediately.
On iOS 7, NSURLSessionTask is actually a __NSCFURLSessionTask (private class) and our NSURLSessionTask category to add the associated object asyncdisplaykit_metadata was crashing on iOS 7 stating that there was no method. This commit changes the category to extend NSURLRequest as well as change NSURLSessionTask to NSURLSessionDownloadTask.
Use ASBasicImageDownloader by default -- you can now do...
ASNetworkImageNode *imageNode = [[ASNetworkImageNode alloc] init];
imageNode.URL = [NSURL URLWithString:@"..."];
[self.view addSubview:imageNode.view];
...and it'll do the right thing.
Add a `usleep(1.0 * USEC_PER_SEC)` delay to ASBasicImageDownloader and
slowly scroll through the Kittens sample project. Without this patch,
you'll see that images only start downloading after their purple
placeholders appear onscreen. With it, images can download and render
before you scroll them onscreen, thanks to the working range.
