Progress HUD for Mac OS X. The HUD include progress and activity indicators. The HUD has been designed to use the indicators to show the status of a process. Present the HUD from any view. With the ability to swap colors easily, you will be able to easily match the look of your application.

If desired, the indicators can be used independently from the HUD.

BlurImageProcessor offers a very easy and practical way to generate blurred images in real time.

CCDebugHelper is a library made to speedup application debug. Instead of clicking interface to get to right view controller you can define all view controllers in your application and easy decide which one should appear on start or list all defined controllers. But, this isn't everything. You can define before actions to prepare your controller to show. There are two version of before action synchronized and asynchronized.

Custom animation transition for presenting modal view controllers.

An iOS collection view subclass to present a list of skewed images and parallax of the images during the scroll!

History

I wanted to make something like this since I saw this: http://capptivate.co/2014/01/18/timbre-2/

While I was waiting to have the time to make it TWRSkewedCollectionView came out.

I forked it and decided to contribute. I was going to add the parallax effect when I realized that there were some decision that I didn't like so I preferred to use that as a base but I need to edit a lot of stuff that probably the original owner do not want to change.

For example: I want a collection view that works like any other collectionView, where the user needs to provide a data source instead of loading a simple list of URL for the images.

Just to have it as exensible as the original CollectionView, and have more reusable code.

I don't like NIBs, and this project shouldn't be a collectionview but just a cell (+ layout for the parallax)

Even for the way how the original is structured is difficult to add the parallax effect or edit the behaviors, and it becomes too much confusing. Instead of use a custom collection view+cell+layout here you just have to use the cell (and the layout if you want the parallax). I tried to made something that preserve all the other behaviors and settings in the collectionView.

At the end I guess there is no code shared between the two, TWRSkewedCollectionView is just simple to use but not as reusable and customizable as I wanted.

This is a simple project inspired by Paper application of Facebook.

NSDictionary+ImageMetadata and NSDictionary-MetadataDatasource are categories for working with image metadata provided by the ImageIO framework.

Preparing a UITableView with image metadata can be done in as little as two lines of code:

self.metadata = [NSDictionary imageMetadataWithImageAtURL:imageURL]; self.tableView.dataSource = self.metadata;

iOS inspector for curious people. Inspect the hierarchy of apps and objects' available methods! Useful for debugging, and knowing how something works.

iOS and OS X implementation of forced graph using SpriteKit. See demo here:https://raw.githubusercontent.com/garnett/DLForcedGraphView/master/img/demo.gif

A simple Cocoa NSScrollView subclass that allows to draw on its top and its bottom small shadow rectangles to provide a subtle and discrete fade effect, for a smoother visual transition.

AFViewShaker is a simple utility for performing UIView shake animations.

A UINavigationController subclass that re-enables the interactive pop gesture recognizer when the navigation bar is hidden or a custom back button is used.

It's described in detail in the blog post: http://holko.pl/ios/2014/04/06/interactive-pop-gesture/

CZWeatherKit is a simple, extensible weather library for iOS and OS X that allows for easy downloading of weather data from various weather services.

A UISlider subclass that improves the precision of selecting values. Please read http://holko.pl/ios/2014/05/26/improving-uisliders-precision/ to learn the background story behind it.

a collection view layout + cell that can do something percent driven ( parallax for image + custom)

A collection view layout and a cell subclass usefull to made parallax of an image during the scrolling. But even thanks to the delegate useful to make cool percent driven effect, in the example I used my MPTextReveal to show you how to use.

Transition between view controllers using pre-built custom transitions. Transition animations include: scale up/scale down, slide in from left/right/top/bottom, slide out to left/right/top/bottom, fade. None of these are all too complicated but will save you some time from creating your own custom animation object. Have an animation suggestion? Let me know and I'll add it to the list!

Subclass of UIButton that gives a colored border around a UIButton. The subclass takes the textColor attribute and creates a border with that color. When a user presses the button, it will change to be filled with the border color creating a solid color button.

A popping label with optional buttons, useful for tutorial-like tips.

Subclass of UICollectionViewFlowLayout and UICollectionViewCell with 'rubbery' effect. Inspired by Nike's 'Making' app.
