Detect a tap on a URL inside a UITextView. Note: the rs_links method isn't included -- you'll need something that takes text and returns an array of detected links. This gist just demonstrates walking through the UITextView characters.
@implementation UITextView (RSExtras)
static BOOL stringCharacterIsAllowedAsPartOfLink(NSString *s) {
/*[s length] is assumed to be 0 or 1. s may be nil.
Totally not a strict check.*/
if (s == nil || [s length] < 1)
return NO;

This is a guard that tracks down UIKit access on threads other than main. This snippet is taken from the commercial iOS PDF framework http://pspdfkit.com, but relicensed under MIT. Works because a lot of calls internally call setNeedsDisplay or setNeedsLayout. Won't catch everything, but it's very lightweight and usually does the job.You might n…

A list of methods and properties conforming to `UIAppearance` as of iOS 12 Beta 3

$ grep UI_APPEARANCE_SELECTOR ./*     | \

A real world usage for git subtrees.

Let's say you have an iOS project, and you want to use some external library, like AFNetworking. How do you integrate it?

With submodules

Add the project to your repo:

git submodule add [email protected]:AFNetworking/AFNetworking.git Vendor/AFNetworking

or something to that effect.

//
// OLD AND BUSTED
//
if ([self.zoomingDelegate respondsToSelector:@selector(zoomingWindow:didZoomOutViewController:)] == YES)
{
// Do something important.
}

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:
