Weekly Roundup: App Architecture

A drop-in UITableView/UICollectionView superclass category for showing empty datasets whenever the view has no content to display.

It will work automatically, by just conforming to DZNEmptyDataSetSource, and returning the data you want to show. The -reloadData call will be observed so the empty dataset will be configured whenever needed. It is (extremely) important to set the dataSetSource and dataSetDelegate to nil, whenever the view is going to be released. This class uses KVO under the hood, so it needs to remove the observer before dealocating the view.

The custom collectionView layout that can perform reordering of cells by dragging it.

Bookshelf like iBooks layout for UICollectionView.

iOS control that acts like indeterminate progress bar

LKAssetsLibrary provides grouping / filtering / sorting functions for ALAssetsLibrary.

Simple NSView or NSViewController based picker for Emoji.

I took the wonderful work of AGEmojiKeyboard (https://github.com/ayushgoel/iOS-emoji-keyboard) as a base to create an OS X version.

Its extremely simple and worth a couple hours of work. Its useful if you want to allow a user to enter Emoji without having to use the "special keyboard" in the edit menu.

An example would be like Messages/iChat which has a smiley face picker next to the text entry.

As a developer, we struggle to understand and reproduce few UI bugs reported by the beta-tester. In tester's point of view, tester writes paragraphs to explain a simple UI misalignment when they test.

Tattle-UI solves this problem by providing simpler mechanism to get UI feedback from beta-testers.

This is a custom button for iOS with a ripple effect. It is simple to integrate and is customizable. Supports a callback using blocks.

RColorPicker is a lightweight color picker for iOS that's easy to use for both users and developers.

PROBLEM

In one of my working projects, I need to show a picker view in a UITableViewController's tableView, so I add a picker view as a subview of the tableView. The result is this picker view will be scrolled together with the tableView.

HOW TO SOLVE THIS

We need a control which can show like modal and block actions, so here comes UIActionSheet. And we have to customize the UIActionSheet to show the picker view.

As we all know, the UIActionSheet can't be dragged into a empty xib, but UIView can. so we start with an UIView and do the layout and then change the class name of the UIView to UIActionSheet. That works fine for some UIView based controls.

JPRequest is a simple Objective-C object to send and receive POST and GET data from a webservice

UAProgressView is a simple and lightweight, yet powerful animated circular progress view.

Contains a Swift file to add the spaceship operator ( <=> ) to a project

6.0 <=> 17.0 // Outputs -1

9001.0 <=> 9000.0 // Outputs 1

4.0 <=> 4.0 // Outputs 0

Works on iOS and OS X but the Xcode project is set up as an OS X command line tool.

An animating search bar.

Originally developed for ShopNow v2. (http://www.shopnow.de)

The search bar is designed as a standalone component that can be easily drag'n'dropped into any existing iOS project.

For a story behind this control see http://salanki.com/insomniac/2014/06/03/the-search-bar-experiment/

A pretty basic implementation to help keep track of a users streak of days where he/she has launched your app.

The component uses NSUserDefaults to keep track of the dates. It also makes use of NSDate+Helpers category used in the PMCalendar repo here: https://github.com/kovpas/PMCalendar which is MIT Licensed.

Install:

Copy TMConsecutiveDayHelper.h and TMConsecutiveDayHelper.m into your project as well as NSDate+Helpers.h and NSDate+Helpers.m.

Place a call to:

[TMConsecutiveDayHelper appLaunched];

In your App Delegate's application didFinishLaunchingWithOptions: method

Then to check on your users streak you can call:

[TMConsecutiveDayHelper streakSizeInDays]; Or Alternatively call:

[TMConsecutiveDayHelper hasComeBackForThisExactNumberOfDaysConsecutively:5] which returns a BOOL

There's no logic as of yet to reset the streak but it could be added quite easily. basically you're responsible for what you want to do with the info and the class just keeps track of the streak itself.

Downsides:

Because the app uses NSUserDefaults it could be gamed pretty easily, by the user changing the date on their device. The component also uses ARC so if your project is using reference counting (ie retain release) then place the compiler flag ' -fobjc-arc ' inside the TMConsecutiveDayHelper.m row under the 'Compile Sources' located within the 'Build Phases' Tab for your App/Target settings.

Yet another accordion style container view.

This is a simple popup menu for iOS. Inspired by iOS7 grouping folder (loook alike) in the springboard. Is is purely based on UIView. Includes flats looks, callbacks using blocks & several options for curved corners & flat corners, bordered popup. This control supports paging using scrolls, so that user can add n number of menu items to the popUp.

Any menu when selected creates a ripple effect on the tapped item.

Simple to use, easy to integrate.

UIViewController category making life easier when working with animations on keybard appearing/disappearing. Provides a simple block based API to set animations to be performed on each of UIKeyboardNotifications.
