michaelochs / lazy-copy-reveal.sh

Created November 23, 2013 13:27

This script copies the Reveal library in your .app file on build time as long as you have Reveal installed and you are not building the configuration 'ReleaseAppStore'. For more info please see my blog post: http://ios-coding.com/improved-way-to-integrate-reveal/

	#!/bin/sh

	APPBUNDLEPATH="${TARGET_BUILD_DIR}/${EXECUTABLE_NAME}.app/"

	REVEALFRAMEWORKPATH="/Applications/Reveal.app/Contents/SharedSupport/iOS-Libraries/libReveal.dylib"

	if [ -f "${REVEALFRAMEWORKPATH}" ] && [ "${CONFIGURATION}" != "ReleaseAppStore" ]; then
	cp "${REVEALFRAMEWORKPATH}" "${APPBUNDLEPATH}"
	fi

michaelochs / .lldbinit

Created November 23, 2013 13:24

If you add this content to your ~/.lldbinit you can launch the Reveal library from within your debugger as long as you have the library added to your app bundle. For more info please see my blog post: http://ios-coding.com/improved-way-to-integrate-reveal/

	command alias reveal_load expr (void)dlopen([(NSString)[(NSBundle*)[NSBundle mainBundle] pathForResource:@"libReveal" ofType:@"dylib"] cStringUsingEncoding:0x4], 0x2);
	command alias reveal_start expr (void)[(NSNotificationCenter*)[NSNotificationCenter defaultCenter] postNotificationName:@"IBARevealRequestStart" object:nil];
	command alias reveal_stop expr (void)[(NSNotificationCenter*)[NSNotificationCenter defaultCenter] postNotificationName:@"IBARevealRequestStop" object:nil];

michaelochs / UINavigationBar+iOS7Tint.m

Created September 20, 2013 08:56

Adds -[UINavigationBar setBarTintColor:] and -[UINavigationBar barTintColor] on iOS6 so that you don't have to check for that all the time.

	#import <objc/runtime.h>


	@implementation UINavigationBar (iOS7Tint)


	static void setter(UINavigationBar self, SEL _cmd, UIColor tintColor)
	{
	self.tintColor = tintColor;
	}

michaelochs / NSNumber+Subscripting.m

Created July 11, 2013 11:59

NSIndexSet subscripting support

	@implementation NSNumber (Subscripting)

	// call it like this: [@0:1];
	- (NSIndexSet*):(NSUInteger)length
	{
	return [NSIndexSet indexSetWithIndexesInRange:NSMakeRange([self unsignedIntegerValue], length)];
	}

	@end

michaelochs / IrisSegue.mm

Last active May 16, 2018 19:42

This is a segue that does an iris animation like the iOS camera app. Note: The name cameraIris is private API and might lead to rejection!

	@implementation IrisSegue

	- (void)perform
	{
	[self.sourceViewController presentViewController:self.destinationViewController animated:NO completion:^{
	// don't ask - it just works with two calls to dispatch_async
	dispatch_async(dispatch_get_main_queue(), ^{
	dispatch_async(dispatch_get_main_queue(), ^{
	NSString* shutterAnimationName = @"cameraIris";

michaelochs / date formatter

Last active December 17, 2015 06:39

Shared Dateformatter for performance optimization

	+ (instancetype)uiDateFormatter
	{
	static NSDateFormatter* uiDateFormatter = nil;
	static dispatch_once_t onceToken;
	dispatch_once(&onceToken, ^{
	uiDateFormatter = [[NSDateFormatter alloc] init];
	uiDateFormatter.dateStyle = NSDateFormatterFullStyle;
	uiDateFormatter.timeStyle = NSDateFormatterNoStyle;
	});
	return uiDateFormatter;
