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)

Download

git clone git://github.com/youknowone/FoundationExtension.git
cd FoundationExtension
git submodule update --init

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

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

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];

performSelector, with 3 object

Foundation

No way. You should use <objc/runtime.h>

FoundationExtension

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

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];

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];

get class name

Foundation

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

FoundationExtension

NSString *className = obj.classObject.name;

encode base64 string (especially for IAP)

Foundation

No way.

FoundationExtension

NSString *base64String = [data base64String];

get hexadecimal value from base 16 string

Foundation

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

FoundationExtension

NSInteger value = [string hexadecimalValue];

How about base 12 string?

Foundation

Why should foundation has this?

FoundationExtension

NSInteger value = [string integetValueBase:12];

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<CC_MD5_DIGEST_LENGTH; i++ )
    [result appendFormat:@"%02x", *(hashedChars+i)];

FoundationExtension

NSString *result = [data digestStringByMD5];

plist dictionary decode from HTTP post request

Foundation

Get data from NSURLRequest. Ehh.. so what can I do now? (Use NSPropertyListSerialization)

FoundationExtension

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:URL];
[request setHTTPPostBody:@{@"key1":@"value1"} encoding:NSUTF8StringEncoding];
NSData *data = [NSData dataWithContentOfURLRequest:request];
NSDictionary *dictionary = [NSDictionary dictionaryWithData:data];

UIColor from HTML color code

FoundationExtension

UIColor *color = [UIColor colorWithHTMLExpression:@"#f0f0f0"];

Change implementation to new one

FoundationExtension

NSAClass *c = obj.classObject;
[c methodObjectForSelector:@selector(method1)].implementation
  = [c methodObjectForSelector:@selector(method2)].implementation;
// now [obj method1] is [obj method2]
