Accessing an API using CoreData's NSIncrementalStore

Note: the original location of this article is on my blog, however, it is posted here too for better readability.

In this article, we will see how to use Core Data for accessing your API. We will use the Bandcamp API as our running example. I've only been experimenting with this code for a few days, so there might be mistakes in there.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

MrRooni

@interface SomeViewController ()

// Declare some collection properties to hold the various updates we might get from the NSFetchedResultsControllerDelegate
@property (nonatomic, strong) NSMutableIndexSet *deletedSectionIndexes;
@property (nonatomic, strong) NSMutableIndexSet *insertedSectionIndexes;
@property (nonatomic, strong) NSMutableArray *deletedRowIndexPaths;
@property (nonatomic, strong) NSMutableArray *insertedRowIndexPaths;
@property (nonatomic, strong) NSMutableArray *updatedRowIndexPaths;

@end

Convert MOV to GIF using FFmpeg and ImageMagick

I tried a few different techniques to make a GIF via command-line and the following gives me the best control of quality and size. Once you're all setup, you'll be pumping out GIFs in no time!

Preparation

Install FFmpeg

• $ brew install ffmpeg [all your options]
  • Example: $ brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

Install ImageMagick
