Articles about programming in Cocoa are many and in many places. The majority of them are of very high quality. To help out, I made this collected index, searchable by title or by article content. This page is very easy to maintain, so please email me any other articles out there that I've missed. Of course, make sure you also know about Apple's Cocoa docs! Also note that there are many Cocoa languages beyond Objective-C.

It’s just that the tide of Android devices is going to be primarily composed of “free with contract” uglies, not the kind of cool phones that compete with the iPhone. (Which is not to downplay cool Android phones, which I suspect will get more competitive, not less.)

It’s a typical design problem: it can’t be heavy and light and big and small. Neither decision will satisfy everyone all the time or cover every edge case: if Apple implemented Mute in Ihnatko’s preferred way, millions of people would be just as irritated when their scheduled alarms didn’t wake them up.

Even with all those reasons, I just can’t believe that there is still only one Android app that I can look at and say: “yes, that’s what I am talking about.”

Even if all the above reasons for not developing for Android are true, it would still seems highly unusual that I was only able to find one good app.

The best guess I have has to be that the “market share” is just not that high, thus not making it “worth” it for developers to make amazing apps for the platform.

Visualize how people interact with your application, find out if they touch the screen in the right place, how far they scroll to view the content or if they use gestures to control your application. Heatmaps SDK lets you increase user retention and satisfaction making your app easy to use.

FastPdfKit is a library that let you show pdf documents in iOS applications bypassing all performances and missing features problems related to QuickLook.

Code signing can be a pain, but the fact that Xcode gives very little information about a mobile provisioning file does not ease things. Let me introduce a new QuickLook plugin. This plugin allows you to get a QuickLook preview for all .mobileprovision files.

iosframeworks.com provides a carefully selected list of frameworks and classes that can be used as building blocks when creating apps for iOS devices.

SSToolkit is a collection of well-documented iOS classes for making life easier by solving common problems all iOS developers face. Some really handy classes are SSCollectionView, SSGradientView, SSSwitch, and any many more.

App Press® is the only web-based CMS tool that allows designers and developers to rapidly build iPad and iPhone apps.

Custom UI Component Database for iOS and Mac OS X

Now that we all are moving our source code gradually to iOS 4 I had to pause and think a bit about where to move which code. A problem that I’m facing frequently when updating a project is that the didFinishLaunching is only called if the app really launches.

ZoomingViewController is a class you can attach to any existing view that will let you zoom the view to fullscreen with a single tap, rotate the view while in fullscreen by rotating the device and tap to return to the original inline state.

In this post, I present a tiny iOS app that generates a continuous tone at a frequency determined by a slider. It's a small sample app intended to show the simplest way to send audio data you generate to the speaker.

No code changes need. Just build your app for the Simulator (rather than the Device), and upload your .app to us. We give you back a link to your app on the web.

In this article, we will show you the building blocks required to incorporate fixed position into your own mobile web applications.

RestKit is a powerful library that simplifies interacting with web services for iOS applications. In this article, written by RestKit creator and Two Toasters CTO Blake Watters, we will take a quick tour of RestKit’s feature set, get familiar with the core concepts presented by the library, and then explore some code samples to get a feel for what working with RestKit is really like.

This post introduces the PuttyView class, which is built to act like a moveable and resizable window-like object in iOS.  It contains one primary view, called the contentView, and moves and resizes that view according to where the user drags their finger
