  A factory for turning Font Awesome pictograms into icon images for user interface controls and buttons. Works for iOS and OS X.

Font Awesome by Dave Gandy - http://fortawesome.github.com/Font-Awesome

For iOS apps, edit your app's Info.plist to contain the key: "Fonts provided by application" (UIAppFonts). Then add "FontAwesome.otf" to the list under that key.

UIAppFonts

<string>FontAwesome.otf</string>

For OSX apps, edit your app's Info.plist to contain the key: "Application fonts resource path" (ATSApplicationFontsPath). Set the value to ".".

ATSApplicationFontsPath .

FontLabel

A project that includes a module for drawing arbitrary .ttf fonts for iPhone.

FontReplacer

Since iOS 3.2, you can use custom fonts in your apps but unfortunately, you can't use these custom fonts in Interface Builder. FontReplacer is a solution to this problem.

If your project contains nibs with a lot of labels, it becomes tedious to setup an outlet for every label and change the font in the code for each outlet. Instead choose a font that you won't be using anywhere in your app, e.g. Arial and use it in Interface Builder. Then create a mapping from Arial to your custom font, e.g. Caviar Dreams and let FontReplacer handle the replacement.

The navigation key (the middle one with a circle on it) allows you to navigate in the text by moving the cursor in a direction where you drag. If you drag the navigation key, the cursor will move the same way as you drag. If you double tap and drag it will start selecting text from your current position. To see the component in action, take a look at the video at http://www.becomekodiak.com/ or try our app called Kodiak PHP on the App Store.

  OCCalendar

  OCCalendar is a very simple component for iPhone/iPad that provides a 'Popover' date picker controller. It is very easy to add to your project, and is 100% CoreGraphics code, so it uses no images, and is resolution independent. I realize that I need to cut down the size for iPhone a bit more. I originally wrote it just for iPad, and my paths and sizing are all just slightly too wide for the iPhone. I'll fix it when I get a chance.

  OCHamcrest

OCMock

This implementation fully utilises the dynamic nature of Objective-C. It creates mock objects on the fly and uses the trampoline pattern so that you can define expectations and stubs using the same syntax that you use to call methods. No strings, no @selector, just method invocations.

OCMockito

OCMockito is an Objective-C implementation of Mockito, supporting creation, verification and stubbing of mock objects.

Key differences from other mocking frameworks:

• Mock objects are always "nice," recording their calls instead of throwing exceptions about unspecified invocations. This makes tests less fragile.
• No expect-run-verify, making tests more readable. Mock objects record their calls, then you verify the methods you want.
• Verification failures are reported as unit test failures, identifying specific lines instead of throwing exceptions. This makes it easier to identify failures. (It also keeps the pre-iOS 5 Simulator from crashing.)

OCTotallyLazy

OCTotallyLazy is a framework that adds functional behaviour to Objective C collection objects, as well as a lazy collection object called Sequence. It's a partial port of Java's TotallyLazy.

ODIN

What is the Open Device Identification Number?

The Open Device Identification Number (ODIN) is a number designed for mobile app developers and service providers to uniquely identify their users’ devices in a convenient and interoperable manner. Unlike existing device identification schemes, ODIN is:

• Anonymous A device’s ODIN does not encode any additional information beyond differentiating it from other ODINs. Having a single ODIN does not reveal any information about the originating device’s user, make, model, etc.
• Consistent ODIN provides a standardized format for identifying devices regardless of software platform. Thus iOS, Android, Windows Phone, and future devices all use the same number format.
• Secure The ODIN specification considers device identifiers to be personal information and details precautions in its transport accordingly. Additionally, even if the identifier were to be captured no additional information would be revealed beyond a unique number.

Maintenance of ODIN is administered by an ODIN Working Group (http://www.odinmobile.org) comprised of industry developers and service providers.

  pegged

  Pegged generates Objective-C parsers from PEG grammars. The parsers it generates are re-entrant, thread-safe, and do not leak memory: they are suitable for inclusion in other programs.

Pegged reads the grammar specified in file and will create a class of the same name. A .h and a .m file will then be created in the output directory, which may be specified from the command line and defaults to the directory containing the PEG grammar. The parser class adheres to a simple interface:

@protocol ParserDataSource;
typedef NSObject<ParserDataSource> ParserDataSource;
@interface Parser : NSObject
{
}
@property (retain) ParserDataSource *dataSource;
- (BOOL) parse;
- (BOOL) parseString:(NSString *)string;
@end

@protocol ParserDataSource
- (NSString *) nextString;
@end

The data to be parsed may either be provided via a data source (which responds to a single selector, -nextString) or via the -parseString: selector.

PHFArrayComparator

This little class is intended to be used with UITableView and other collection like views. It's purpose is to facilitate the smooth update of displayed data. It does that by telling you what is gone, what moved, and what is new in the data. These can then be directly translated to table view methods that insert, move, and delete rows or sections.

proj4

PROJ.4 is in active use by GRASS GIS, MapServer, PostGIS, Thuban, OGDI, Mapnik, TopoCad, and OGRCoordinateTransformation as well as various other projects.

Since work started on the PROJ.4.4.x series of releases, various bug fixes have been incorporated, and the build system has been overhauled to use autoconf/libtool. Support has also been added for 3 and 7 parameter datum shifts, the PJ structure now also carries datum information and PJ can be considered a full coordinate system (geographic coordinate systems are also now supported with the +proj=latlong pseudo-projection). The new cs2cs program performs a similar function to the proj program, but transforming from any one coordinate system to another. The new pj_transform() is used to access the extended coordinate system to coordinate system transformation with datum shifting. Work is underway to improve ThreadSafety.

A mapping file (epsg) has also been introduced mapping most EPSG ( http://www.epsg.org/) coordinate systems to PROJ.4 format.

As of May 2008 PROJ.4 has become part of the MetaCRS project, a confederation of coordinate systems related projects and it is hoped MetaCRS will enter incubation as an OSGeo project.

PRTween

While Apple has done an incredible job with UIView Animations and Core Animation, there are sometimes cases that are difficult to get around. PRTween is a great alternative if you'd like to: Animate a property Core Animation won't allow you to Ensure that [someView layoutSubviews] is respected during an animation Tween arbitrary numerical values, such as sound volume, scroll position, a counter, or many others Define your timing curve as a function rather than a bezier with control points PRTween aims to be as simple as possible without sacrificing flexibility. In many cases, an animation may be as simple as: [PRTween tween:someView property:@"alpha" from:1 to:0 duration:3]; In order to promote simplicity, PRTween can be used as a drop-in replacement for most animations in your app. This means that in the case displayed above, the end result is identical to writing a UIView animation yourself.

SKBindingManager

SKBindingManager - lightweight bindings for iOS

SKBindingManager is component which allows you to easily add bindings to your code with support for ARC.

It is designed so you can bind two objects or UIViews, or any other combination of those two. Basic purpose of this component is to enable binding between models and Views without having to write a lot of unnecessary code which handels everything.

SKBindingManager allows you to dynamically add or remove bindings. You can specify wheather you would like one-way or two-way binding. It has an integrated support for cycle detection in your bindings. For instance if you have object A with properties a, b and c. You will not be allowed to make bindings like this A.a -> A.b -> A.c -> A.a because that would cause bindings to refresh themselves indefinetly. You can also define specific transformations you want to do before for instance A.a refreshes object A.b via blocks.

unoffical-twitter-sdk

Unoffical Twitter SDK

While creating an app which needed simple twitter interactions i found that all of the exisiting libraries used OOB signon. I also found that all the libraries looked different to the facebook login method. What i have done is using the code from the facebook-ios-sdk built something that behaves the same as the facebook-ios-sdk without using OOB login for oAuth.

The license is Apache 2.0, as i copied a lot of code from the facebook-ios-sdk. All of the copied code is in TwitterDialog.h/.m

I also copied alot of code from https://github.com/jaanus/PlainOAuth as the basis of this project.

The credit here should really go to Facebook and Jaanus Kase because all i have done is put their code together and made something new.

It should be fairly self explanatory to use, but it was written quickly and might still be buggy. If you know of any bugs please tell me so i can fix them, or submit a pull request.

zipzap

The zip file is an ideal container for compound Objective-C documents. Zip files are widely used and well understood. You can randomly access their parts. The format compresses decently and has extensive operating system and tool support. So we want to make this format an even easier choice for you. Thus, the library features:

• Easy-to-use interface: The public API offers just three classes! Yet you can look through zip files using familiar NSArray collections and properties. And you can zip, unzip and rezip zip files through familiar NSData, NSStream and Image I/O classes.
• Efficient implementation: We've optimized zip file reading and writing to reduce virtual memory pressure and disk file thrashing. Depending on how your compound document is organized, updating a single entry can be faster than writing the same data to a separate file.
• File format compatibility: Since zipzap closely follows the zip file format specification, it is works with most Mac, Linux and Windows zip tools.
