akuraru / NSArray-Fanctional.h

Created October 10, 2012 12:03

Objective-Cで関数型プログラミングしたいなーと思ってやってみた。とりあえずFizzBuzz

	#import <Foundation/Foundation.h>

	typedef id (^fanc_t)(id);
	typedef void (^noReturn_t)(id);

	@interface NSArray (Fanctional)

	+ (NSArray *)from:(NSInteger)from to:(NSInteger)to;

	- (NSArray *)map:(fanc_t)fanc;

[Objective-C]ランダムな長さのランダムな文字列を作る

	- (NSString *)randStringWithMaxLenght:(NSInteger)max {
	NSInteger length = [self randBetween:1 max:max];
	unichar letter[length];
	for (int i = 0; i < length; i++) {
	letter[i] = [self randBetween:65 max:90];
	}
	return [[NSString alloc] initWithCharacters:letter length:length];
	}
	- (NSInteger)randBetween:(NSInteger)min max:(NSInteger)max {
	return (random() % (max - min + 1)) + min;

Objective-Cでタプル

	#define tuple(_1, _2) [Tuple tupleWithFirst:_1 second:_2];

	@interface Tuple : NSObject

	@property (readonly, nonatomic) id _1;
	@property (readonly, nonatomic) id _2;

	+ (id)tupleWithFirst:(id)_1 second:(id)_2;
	- (id)initWithFirst:(id)_1 second:(id)_2;

segueのidをいちいち比較するのが面倒なので、最近はこんな感じで書いてたりする。senderがBlocks以外だったらどうするか？知りませんよそんなの


	- (IBAction)touchMove:(id)sender {
	__weak typeof (self) this = self;
	[self performSegueWithIdentifier:kSeguePicture sender:^(id controller) {
	[controller setViewObject:this.viewObject];
	}];
	}

	- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(void (^)(id))sender {
	if (sender) {

	@implementation HogeViewController {
	__weak IBOutlet UIView *piyo;
	}

Objective-Cで翌日の9時を取得する

	// pod 'NSDate-Escort'

	#import "NSDate+AZDateBuilder.h"

	NSDate *date = [[[NSDate date] dateByAddingDays:1] AZ_dateByUnit: @{

ぶどう問題。最後の方は明らかに力尽きている

	require 'set'

	class Bunch
	def initialize(bunch1, bunch2 = nil)
	(bunch2 != nil) ? mergeBunch(bunch1, bunch2) : initValue(bunch1)
	end
	def initValue(value)
	@bunch1 = nil
	@bunch2 = nil
	@value = value
