[![Build Status](https://travis-ci.org/youknowone/FoundationExtension.svg?branch=master)](https://travis-ci.org/youknowone/FoundationExtension)

This library includes small Cocoa/UIKit extensions. This library does not includes high-level data structure, algorithm or frameworks, but collection of code snippets.

 * Many common snippets in a method call.

 * Looks like native foundation methods - It follows Apple Coding Guideline and Foundation naming convention.

See document on [Github] (http://youknowone.github.com/FoundationExtension)

# How to use

* Compiled library

  1. Build project

  2. Add FoundationExtension or UIKitExtension target as dependency

* Directy source

  1. Add files what you need to your project

* CocoaPod ~> 1.7.5

  1. Visit and follow http://cocoapods.org/

If your compiler is gcc or old clang, add '-force\_load' to static library.

# Download for editing

    git clone git://github.com/youknowone/FoundationExtension.git

    cd FoundationExtension

    git submodule update --init

# Why useful

Make your code short! Do not allow evil objc to make your code verbose.

This library includes many shortcuts for common work.

## NSData from URL

Foundation

    NSString *URLString = [NSSring stringWithFormat:@"http://"HOST_URL"/api/%@", key];

    NSURL *URL = [NSURL URLWithString:URLString];

FoundationExtension

    NSURL *URL = [[@"http://"HOST_URL"/api/%@" format:key] URL];

@see @ref NSString(Shortcuts)

@see @ref NSString(NSURL)

## iPhone MAC Address

Foundation

  * No way.

FoundationExtension

    [[UIDevice currentDevice] MACAddress]

@see @ref UIDevice(Shortcuts)

## performSelector, with 3 object

Foundation

  * No way. You should use 

FoundationExtension

    [obj performSelector:sel withObject:o1 withObject:o2 withObject:o3];

@see @ref NSObject(ObjCRuntime)

## Get NSData from post request

Foundation

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];

    [request setHTTPMethod:@"POST"];

    [request setHTTPBody:@"field1=value1"];

    NSData *data = [NSURLConnection sendSynchronousRequest:request returningResponse:NULL error:NULL];

FoundationExtension

    NSData *data = [NSData dataWithContentsOfURL:URL postBody:@{@"field1":@"value1"} encoding:NSUTF8StringEncoding];

@see @ref NSData(NSURLRequest)

## Get NSData from Multipart Form POST

Foundation

  * No way.

FoundationExtension

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];

    [request setHTTPMultiPartFormPostBody:@{@"filename":data} encoding:NSUTF8StringEncoding];

    NSData *data = [NSData dataWithContentOfURLRequest:request];

@see NSURLRequestAdditions.h

## Truncate strings in array

Foundation

    NSMutableArray *newArray = [NSMutableArray array];

    for (NSString *s in array) {

        [newArray addObject:[s substringToIndex:20]];

    }

FoundationExtension NSArray

    NSArray *newArray = [array arrayByMappingOperation:^(NSString *obj){ [obj substringToIndex:20]; }];

FoundationExtension NSMutableArray

    [array map::^(NSString *obj){ [obj substringToIndex:20]; }];

@see @ref Map/Filter/Reduce

@see NSAFunctional.h

## Get a class name

Foundation

    NSString *className = [NSString stringWithUTF8String:class_getName(obj.class)];

FoundationExtension

    NSString *className = obj.class.name;

@see @ref NSObject(ObjCRuntime)

@see @ref NSObject(ObjCRuntimeClass)

## Get hexadecimal value from base 16 string

Foundation

    int value;

    sscanf(string.UTF8String, "%x", &value);

FoundationExtension

    NSInteger value = [string hexadecimalValue];

@see @ref NSData(Serialization)

## How about base 12 string?

Foundation

  * Why should foundation has this?

FoundationExtension

    NSInteger value = [string integerValueBase:12];

@see @ref NSString(Evaluation)

## md5 hash

Foundation

    unsigned char hashedChars[CC_MD5_DIGEST_LENGTH];

    CC_MD5([data bytes], (CC_LONG)[self length], hashedChars);

    NSMutableString *result = [[NSMutableString alloc] init];

    for ( int i = 0; i
