Today's iOS Developer Resources, Articles and Open Sources

1. Example: An Open Source iOS App For Creating Apps With An Excellent User Interface

A newly open sourced iOS Objective-C app that has been in the app store that allows users to create their own apps within the app using a great wysiwyg app creation app.

You can download the AppSlate source code through Github here.

You can find AppSlate on the App Store here.

No statement about the exact licensing as of yet, but it is stated that you can "download, compile and modify".

2. Open Source iOS Library For Detecting When A User Is Taking A Screenshot

An iOS Objective-C library that allows you to detect when the user has taken a screenshot.

You can find ShotBlocker with usage instructions on Github here.

A simple solution to this problem. Chpwn has written on his blog about how taking screenshots cancels all screen touches so possibly using UILongPressGestureRecognizer and looking for the state to be UIGestureRecognizerStateCancelled rather than polling based on a timer could be a better approach.

3. Open Source iOS UI Control Mimicking A UITableView Within A UIAlertView

An open source iOS Objective-C user interface control for creating a UIAlertView with an embedded table view.

You can find MLTableAlert on Github here.

You can read more about the creation of this control on the Matthew Labs blog  here.

A sample project is included, and it makes for a great selector style view.  The feature set is different from SBTableAlert and in my testing worked great.

4. Category Allowing You To Recreate The Mac OS X Genie Animation Effect On An iOS UIView

An open source iOS Objective-C user interface control allowing you to create the genie animation effect used for opening/closing
windows in Mac OS X.

You simply need to define the duration, and the starting or ending rectangle size.

You can find BCGenieEffect on Github here.

You can also find this Stackoverflow question thread that explains the technique used transform a rectangle into a quadrilateral.

An  very well done implementation of this staple Mac effect.
