ASDepthModal

ASDepthModal is mostly inspired by a nice CSS work from http://lab.hakim.se/avgrund/.

It gives a sense of depth between the current fullscreen view which is sent backward with a blur effect and a modal popup view which appears in front.

Works on iOS 5 and 6.

The blur effect is a code borrowed from https://github.com/rnystrom/RNBlurModalView.

Try it

Download the whole project and run it under Xcode. You can choose either iPhone or iPad destination. It supports all orientations change.

Use it

Just copy ASDepthModalViewController.h, ASDepthModalViewController.m, UIImage+Blur.h and UIImage+Blur.m in your project and #import "ASDepthModalViewController.h" where you need it.

You can also add pod 'ASDepthModal' to your Podfile.

Show

Once you have your popup view, here is how you would present it

[ASDepthModalViewController presentView:yourPopupView];

Hide

The popup view is automatically closed as soon as you tap outside of it.

If you need to close the popup view by code (you usually have a "close" button for this purpose)

[ASDepthModalViewController dismiss];

Configure

You can configure the background color as well and different kind of options:

  • the effect applied on the popup when it appears ans disappears
  • whether the underlay view is blurred
  • whether a tap outside of the popup closes it. You can also add some code to execute once the popup is closed.
[ASDepthModalViewController presentView:yourPopupView
                        backgroundColor:color
                                options:options
                      completionHandler:handler];

Three styles are available : no effect, grow effect or shrink effect.
