Using the "More" button. Of course the simple way that Apple uses in Mail/iOS is not public. rdar://16600859

	- (NSString )tableView:(UITableView )tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath {

	// Hide the More/Delete menu.
	[self setEditing:NO animated:YES];

Declare on your main init that all other init methods should call. It's a nice additional semantic warning. Works with Xcode 5.1 and above. Not tested with earlier variants, but should just be ignored. A reference to this macro shortly appeared in https://developer.apple.com/library/ios/releasenotes/ObjectiveC/ModernizationObjC/AdoptingModernObj…

	#ifndef NS_DESIGNATED_INITIALIZER
	#if __has_attribute(objc_designated_initializer)
	#define NS_DESIGNATED_INITIALIZER __attribute((objc_designated_initializer))
	#else
	#define NS_DESIGNATED_INITIALIZER
	#endif
	#endif

	/**
	Provides the ability to verify key paths at compile time.

	If "keyPath" does not exist, a compile-time error will be generated.

	Example:
	// Verifies "isFinished" exists on "operation".
	NSString *key = SQKeyPath(operation, isFinished);

	// Verifies "isFinished" exists on self.

Works around the issue where UITextView doesn't scroll to the new line until there's a character in there. Super horrible workaround.

	- (BOOL)textView:(UITextView )textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString )text {
	// Horrible HACK for bug in UITextView where it won't scroll to the new line after pressing enter in the text view.
	// I feel dirty for having to write this. Buggy at least within iOS 7.0 - 7.1b1.
	if (PSPDFIsUIKitFlatMode() && [text isEqualToString:@"\n"] && range.location == textView.text.length) {
	dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC));
	dispatch_after(popTime, dispatch_get_main_queue(), ^{
	CGPoint contentOffset = textView.contentOffset;
	CGFloat fontSize = textView.font.pointSize;
	if (textView.contentSize.height - fontSize > textView.bounds.size.height) {
	contentOffset.y += fontSize + 2.f; // add spacing

Detect if you're currently running a development version or an App Store/Ad Hoc version.

	static BOOL PSPDFIsDevelopmentBuild(void) {
	#if TARGET_IPHONE_SIMULATOR
	return YES;
	#else
	static BOOL isDevelopment = NO;
	static dispatch_once_t onceToken;
	dispatch_once(&onceToken, ^{
	// There is no provisioning profile in AppStore Apps.
	NSData *data = [NSData dataWithContentsOfFile:[NSBundle.mainBundle pathForResource:@"embedded" ofType:@"mobileprovision"]];
	if (data) {

Delegate proxying (`protocol_methodForEach()` is a custom function that does just what its name implies)

	@interface DDDelegateProxy : NSProxy

	+ (id)proxyForDelegate:(id)delegate conformingToProtocol:(Protocol *)protocol;

	@property (weak, readonly) id delegate;
	@property (strong, readonly) Protocol *protocol;

	/*!
	* Set a default return value for a method on the delegate's protocol.
	* \param value This must be a block that returns the default value. Bad Things will happen if it's not.

steipete / UIKitLegacyDetector.m

A simple way to detect at runtime if we're running in UIKit legacy mode or the new "flat" variant. Written for our PDF iOS SDK (http://pspdfkit.com), where the precompiled binary needs to detect at runtime in what variant it's running. Want more stuff like that? Follow me on Twitter: http://twitter.com/steipete

	// Taken from http://PSPDFKit.com. This snippet is under public domain.
	#define UIKitVersionNumber_iOS_7_0 0xB57
	BOOL PSPDFIsUIKitFlatMode(void) {
	static BOOL isUIKitFlatMode = NO;
	static dispatch_once_t onceToken;
	dispatch_once(&onceToken, ^{
	// We get the modern UIKit if system is running >= iOS 7 and we were linked with >= SDK 7.
	if (kCFCoreFoundationVersionNumber >= kCFCoreFoundationVersionNumber_iOS_7_0) {
	isUIKitFlatMode = (NSVersionOfLinkTimeLibrary("UIKit") >> 16) >= UIKitVersionNumber_iOS_7_0;
	}

Search the current directory for unused images. Useful for finding leftover assets from files which exist in Xcode project or in your repository.

	# This simple python utility crawls the current directory and finds all images.
	# It will then search the directory for files using these images and also mark
	# any xcode projects which include these images.
	#
	# Allowing you to easily find images which are no longer used (or even images
	# included in xcode and not used).
	#
	# Usage, cd into your repository and then run:
	#
	# curl https://gist.github.com/kylef/6316920/raw/images.py -# \| python -
