bleeckerj / NSDataExtensions.swift

Created February 3, 2017 04:18 — forked from tanner0101/NSDataExtensions.swift

Convert to and from NSData for common Swift types. Includes Eddystone URL conversion.

bleeckerj / Data to UInt32

Created February 7, 2017 02:18

Two idioms for converting Data representing 4 UInt8's into a UInt32

	do {
	let count = 1 // number of UInt32s
	let stride = MemoryLayout<UInt32>.stride
	let alignment = MemoryLayout<UInt32>.alignment
	let byteCount = count * stride

	var bytes : [UInt8] = [0x0D, 0x0C, 0x0B, 0x0A] // little-endian LSB -> MSB
	var data : Data = Data.init(bytes: bytes)

	print("---------------- 1 ------------------")

bleeckerj / DataToTypedPointerConversion

Last active February 7, 2017 04:01

Given a Type and some Data, convert to and return the Type in that Data

	let bytes : [UInt8] = [0xF1, 0xE1, 0xD1, 0xC1, 0xB1, 0xA1, 0x91] // little-endian LSB -> MSB
	let data : Data = Data.init(bytes: bytes)

	let result = convert(from: data, to:UInt32.self, at:3)
	print("\(String(format: "0x%8X",result!))")
	print(result!)



	func convert<T>(from data: Data, to: T.Type, at offset:Int) -> T? {

bleeckerj / NSData+Convert.swift

Created February 7, 2017 04:49

Adds a simple conversion to specified Type treating Data a bit like a Struct.

bleeckerj / RxToggleTrueFalse

Last active February 9, 2017 05:49

Toggle between true and false at an interval in RxSwift, bound to a UISwitch and enabling/disabling a UITextField in the bargain

	@IBOutlet weak var usernameOutlet: UITextField!
	@IBOutlet weak var switchOutlet: UISwitch!

	let t = Observable<Int>.interval(1, scheduler: MainScheduler.instance).take(4)
	let trueOrFalse = t.mapWithIndex{ $0 }.map{ $1 % 2 == 0 }
	_ = trueOrFalse.bindTo(switchOutlet.rx.isOn)
	_ = trueOrFalse.bindTo(usernameOutlet.rx.isEnabled)


	_ = trueOrFalse.subscribe(onNext: {

bleeckerj / RxSkipEveryNth

Created February 9, 2017 06:02

Skip every Nth element in a sequence RxSwift

	let a : [Int] = [1,2,3,4]
	let n = Observable<Int>.from(a).mapWithIndex{ $0 }
	.filter {$1 % n == 0 }
	.map{ $0.0 }

	_ = n.subscribe(onNext: {
	print("every nth \($0)")
	})

bleeckerj / RxEveryNthOfFixedLengthSequence

Last active February 10, 2017 00:18

Pick Every Nth Elements Of Fixed Length Sequence in RxSwift

	let a : [Int] = [1,2,3,4,5,6,7,8,9,10]

	Observable<Int>.interval(1, scheduler: MainScheduler.instance)


	Observable<Int>.interval(2, scheduler: MainScheduler.instance).mapWithIndex{ $0 }.filter { ($1 % 2 == 0 && $1 < a.endIndex)}.map{ a[$0.0]}.subscribe(onNext: {
	print("every 2nd \($0)")
	})
