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";

	@implementation NSNumber (Subscripting)

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

	@end

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 / .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 / 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/"

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
