wh1pch81n / UIKit_Animator_API.swift

Created December 10, 2016 22:18

A wrapper that allows you to set animation and completion handler in a more consistent way

	extension UIKit.UIView {

	public class Animator {
	fileprivate var animatorBlock: ((@escaping () -> (), @escaping (Bool) -> ()) -> ())
	fileprivate var animations: () -> () = { _ in }

	public init(animatorBlock: @escaping ((@escaping () -> (), @escaping (Bool) -> ()) -> ())) {
	self.animatorBlock = animatorBlock
	}

wh1pch81n / UIViewAnimation_as_block

Created December 7, 2016 19:02

using Currying on UIView Animation

	public class func animation(withDuration duration: TimeInterval) -> (@escaping () -> ()) -> (@escaping (Bool) -> ()) -> Void {
	return { (animations: @escaping () -> ()) in
	return { (completion: @escaping (Bool) -> ()) in
	UIView.animate(withDuration: duration, animations: animations, completion: completion)
	}
	}
	}

wh1pch81n / enum_count.swift

Last active November 5, 2016 06:12

A method to help count enums. The switch statement will enforce you cover a state where you count. This is in response to this: https://github.com/jtbandes/swift-evolution/blob/case-enumerable/proposals/0000-derived-collection-of-enum-cases.md

	enum Planets {
	case Mercury
	case Venus
	case Earth
	case Mars
	case Jupiter

	static let count: Int = _count()
	private static func _count(_ first: Planets = .Mercury) -> Int {
	print("blahp")

wh1pch81n / simplified_NS_STRING_ENUM.h

Created November 5, 2016 03:12

Using NS_STRING_ENUM can be verbose when used in objective c. Below is an example of how macros can be used to shorten it. These macros can be used and reused by cleverly defining and underlining macros.

	//global macro helpers
	#define DH_Str(I) #I
	#define __DH_STRING_ENUM(PREFIX, SUFFIX, PREFIX2, SUFFIX2) \
	static PREFIX PREFIX##_##SUFFIX = @DH_Str(PREFIX2##SUFFIX2);
	#define _DH_STRING_ENUM2(PREFIX, SUFFIX, VAL) \
	static PREFIX PREFIX##_##SUFFIX = VAL;
	#define _DH_STRING_ENUM(T,I) \
	__DH_STRING_ENUM(T, I, T, I)
	//------ file dependent
	// the enum type shall be DHBlahKey

wh1pch81n / almostProtected.swift

Created November 5, 2016 01:43

Swift has no access modifier "Protected". Below is the closest thing to protected. You can call this semi-protected.

	import UIKit

	// discourage directly setting property m by using private(set). Anyone can still set the value of the property via setValue(_ :forKey:)

	public class Abe: NSObject {
	public private(set) var m: [String] = ["abc"]
	}

	public class Billy: Abe {
	override init() {

wh1pch81n / page_names.swift

Last active October 8, 2016 03:12

An example of stringifying an enum string state

	enum PageNames: String {
	case sc🖍search = "MySearch"

	var page_name: String {
	return String(describing: self).replacingOccurrences(of: "🖍", with: "/")
	}
	}

	PageNames.sc🖍search.rawValue // "MySearch"

wh1pch81n / ABC_Project_preprocessorDirective_example_Debug

Created September 16, 2016 02:47

	// This is a conditional inclusion.
	// It searches for a file called Captain.xcconfig that lives one file level up in relation to this file.
	#include? "../Captain.xcconfig"

	#if ABC
	// Code between here that runs only when ABC exists
