Simple and intuitive alert view. Similar to push notification effect. This class uses UIAlertView default methods and protocols.

Requirements

NZAlertView works on iOS 6.0+ version and is compatible with ARC projects. It depends on the following Apple frameworks, which should already be included with most Xcode templates:

• Foundation.framework

You will need LLVM 3.0 or later in order to build NZAlertView.

NZAlertView use UIImage-Helpers project for manipulating images.

Alternatively you can directly add source files to your project.

1. Download the latest code version or add the repository as a git submodule to your git-tracked project.
