Weekly Roundup: Coding in Anger

This is a parallax for the cells inside UICollectionView. It gives us an effect just like scrolling the images in Whatsapp or scrolling through the Weather app for iOS.

A UIActivity subclass that share files via GCDWebServer with Twitter Bootstrap UI.

Xcode plugin to optimize images using ImageOptim.

A UIView category to make autolayout (more) readable and less verbose. Write this:

[view lyt_centerInParent];

Instead of:

NSLayoutConstraint *centerXConstraint = [NSLayoutConstraint
    constraintWithItem:view attribute:NSLayoutAttributeCenterX
    relatedBy:NSLayoutRelationEqual toItem:view.superview
    attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0];

[view.superview addConstraint:centerXConstraint];

NSLayoutConstraint *centerYConstraint = [NSLayoutConstraint
    constraintWithItem:view
    attribute:NSLayoutAttributeCenterY
    relatedBy:NSLayoutRelationEqual toItem:view2
    attribute:NSLayoutAttributeCenterY multiplier:1.0 constant:0];

[view.superview addConstraint:centerYConstraint];

UICollectionView layout for both horizontal and vertical management of hexagonal cells

Button with rounded border and animation, which is identical to AppStore's open/download/update/.. button.

A UIWebView ViewController to be used with a UINavigationController or on its own as a modal segue.

KAWebViewController is a view controller class for UIWebView. I never found a similar solution that suited my needs so I decided to write my own basic UIWebViewController Class. You can use KAWebViewController outside a navigation controller with the use of KAWModalWebViewController. Feel free to use this as base for your own UIWebView ViewController. This class currently supports:

• iPad and iPhone
• iOS 6.1 to 7.1 (iOS6 on iPad could use some UI improvements)
• Portrait & Landscape mode

iOS UIImageView subclass - download image with different progress indicators

One viewController can display multiple viewController, works like Tabbar or set of UIButton can placed anywhere by just connecting segues.

iOS library to create elegant, interactive clocks.

iOS audio playing (both local and streaming) made easy through a complete and block-driven Objective-C class. AFSoundManager uses AudioToolbox and AVFoundation frameworks to serve the audio. You can pick a local file or you can use a URL to stream the audio, the choice is up to you.

Custom transition between viewcontrollers holding tableviews. Each cell is animated to simulate a 'wave effect'.

Class to keep any selected input fields visible on screen when the keyboard is shown.

A lightweight view that adds marquee scrolling to any view.

Add gravity bouncing to UIScrollView content.

An easy way to store user preferences using NSUserDefaults.

A 2D table view for iOS apps, that works just like UITableView! This is the demo project, the code is available here: https://github.com/mochidev/MDSpreadView

Xcode plugin that highlights the current editing line in Xcode

A UICollectionViewLayout that uses supplemental views to display a folder below a cell that looks like the screen was split. Mimics the pre iOS7 springboard groups visualization. Wrote this because all of the other "folder" controls like this use a screen shot to do the splitting, but I wanted my collection view to still be functional even with the folder open.

Temporarily adds a loading indicator below the title of your view controller.

Augmented Reality classes that track and display the sun position on the screen

NYSegmentedControl is a customizable, animated replacement for UISegmentedControl inspired by controls found in Instagram, Foursquare, and other apps.

Custom container view controller ala MailBox app.

A iOS 7 NotificationCenter like view that helps you visualizing background elements just putting for example a white object on its top!

A block-based widget that brings slide-to-confirm interfaces to your apps.

Caveat emptor: Dream Engine has had apps approved with this widget, but we make no claim as to whether or not it is generally safe for the App Store.

A cycling or looping scroll view for banners and galleries.
