`NSFormattingContextDynamic` makes a formatter return string proxies that change based on where you but them inside a format string.

	NSDate *date = [NSDate new];

	NSDateFormatter *dateFormatter = [NSDateFormatter new];
	dateFormatter.locale = [NSLocale localeWithLocaleIdentifier:@"nl_NL"];
	dateFormatter.dateStyle = NSDateFormatterFullStyle;
	dateFormatter.formattingContext = NSFormattingContextDynamic; // this is the important setting

	NSString *dateString = [dateFormatter stringFromDate:date];

	NSString *s1 = [NSString stringWithFormat:@"Foo %@", dateString]; // "Foo dinsdag 13 december 2016"

Created July 16, 2016 13:27

michaelochs / NSCharacterSet+Logographic.m

Created December 17, 2015 12:32

A NSCharacterSet containing (hopefully) all logographic characters from unicode.

	#define CharacterRange(__from__, __to__) NSMakeRange(__from__, __to__ - __from__ + 1)

	@implementation NSCharacterSet (HRSCharacterSet)

	+ (instancetype)logographicCharacterSet
	{
	NSRange ranges[] = {
	CharacterRange(0x2E80, 0x2EFF), // CJK Radicals Supplement

	CharacterRange(0x3300, 0x33FF), // CJK Compatibility

michaelochs / ExtendUITableViewDelegate.m

Created August 26, 2015 14:18

An example of how we at HRS expand the `UITableViewDelegate` protocol to trigger custom actions from a cell and communicate them to the table view's delegate.

	@protocol HRSStepperTableViewCellDelegate<UITableViewDelegate>
	- (void)tableView:(UITableView )tableView didChangeStepperValue:(UIStepper )stepper forRowWithIndexPath:(NSIndexPath *)indexPath;
	@end

	@implementation HRSStepperTableViewCell

	- (UITableView *)tableView {
	UIView *superview = self.superview;

	while (superview != nil && [superview isKindOfClass:[UITableView class]] == NO) {

michaelochs / LocalNotifications.m

Last active August 29, 2015 14:23

Short snipped with an explanation of how your app needs to respond to local notifications.

	- (BOOL)application:(UIApplication )application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {
	UILocalNotification *localNotification = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];
	if (localNotification) {
	// the user opened your app by tapping either the notification banner, the notification
	// center entry or the open action in the alert view of the notification while your app
	// was not running / suspended.
	// This is where you want to react to the user's action!
	}
	}

michaelochs / post-checkout

Created March 12, 2015 07:50

A git post checkout hook that ensures your pods are up to date. If there are no changes in the pods environment, this script does nothing.

	#!/bin/sh

	diff "Podfile.lock" "Pods/Manifest.lock" > /dev/null
	if [[ $? != 0 ]] ; then
	echo 'CocoaPods needs some more clean up...'
	echo 'Quit iOS simulator...'
	osascript -e 'tell app "iPhone Simulator" to quit'
	echo 'Quit Xcode...'
	osascript -e 'tell app "Xcode" to quit'
	pod install
