JWFolders is a class that attempts to mimic the folder animation present on the iOS SpringBoard.
JWFolders is being used in my commercial application, QuickWeather. Depicted here is a beta version of the app:
Just include the entire folder,
JWFolders, in your project. Import
JWFolders.h in the class in which you wish to create the folder.
Here's a quick example of how to create a new folder and open it upwards.
JWFolders *folder = [JWFolders folder]; folder.contentView = self.sampleFolder.view; folder.containerView = self.view; folder.position = openPoint; folder.direction = JWFoldersOpenDirectionUp; folder.contentBackgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"noise"]]; folder.shadowsEnabled = YES; folder.showsNotch = YES; [folder open]; // opens the folder.
An issue can arise if the folder is set to show the notch, and the
position is set to a point with an x-coordinate of 0. The notch will appear to be cut off on the left side of the screen. This can be simply resolved by providing a non-zero x-coordinate. Most likely this will be the center of the item from which you present the folder.
Please check the header file for complete documentation.
##ARC The project currently uses Automatic Reference Counting, which means that if your project does not use ARC there will be memory leaks. There are no plans to create a non-ARC branch at this time.
This library makes use of
renderInContext: method to render the current state of your view into an image. Unfortunately,
renderInContext: does not take 3D transforms into account. If you would like this to be fixed, please file a radar.

- Finish implementing the animated notch content to complete the effect.
- Optimize the
renderInContext:call. I fear this is impossible.
Please feel free to fork the project and improve it as much as possible!
