If you’re working with a remote Web Service, your apps are probably displaying TableViews of objects. As soon as your dataset grows beyond 20 or 30 objects, it’s time to implement sections in your Table View. I’m going to show you how you can do this without too much trouble. In this example, we’ll use an array of dictionary objects (Books) to construct a single ‘sections’ dictionary that will be

Today I’m going to show you how to make a static library for iOS. We will make a simple library and use it in a separate project. What’s a static library Here is what has to say: In computer science, a static library or statically-linked library is a set of routines, external functions and variables which are resolved in a caller at compile-time and copied into a target application by a compiler,

Hello, I’m () and I recently finished working on . Many applications use Facebook for posting content from their respective applications, there could be infinite items that a developer would like to post to users feeds whilst using their applications but today we will be focusing on posting a link to a users feed. In order to get started using the Facebook SDK & API’s you will need to download the

This tutorial will show you how to automatically fill in CFBundleVersion and CFBundleShortVersionString, when using Git. This has been tested in Xcode 3.2.5 (Updates for Xcode 4 at the bottom) Git Setup First off you need a project that is checked into git, and is also tagged with an initial version number. If you already have git setup for your project, skip down to XCode Setup To locally setup u

Hello iCoders, today I am going to be open sourcing a UITableViewCell we have created over at ELC that we have found to be very useful. When developing apps we have found that many times a form of some type is required. This is common in Registration forms, contact forms, feedback forms, etc. The problem was writing the same basic code over and over to have an elegant fast form experience for the

Introduction Table Views are one of the most common things within iPhone Applications. The standard UITableViewCells that are provided by Apple are nice but have always had a HUGE flaw in my mind. When you apply some text to the textLabel or detailTextLabel of a UITableViewCell the length of the text is not considered at all. If the text is longer than a single line you need to set the numberOfLin

Overview If you have an iPad you have probably used iBooks, Apple’s eBook application that gives users access to the iBooks store. In this application you can navigate through books in a number of ways. Today we are going to focus on the scroll bar at the bottom of a book that a user can utilize to skip to any given page within the book. This control involves a customized UISlider and a UIPopoverV

Hey iCoders! Today we are going to make a fun project that takes advantage of UIGestureRecognizers which were introduced in iOS 3.0, way back when it was called iPhone OS. UIGestureRecognizer is an abstract class that several concrete classes extend Eg. UITapGestureRecognizer, UIPinchGestureRecognizer. Today we are going to be building a simple photo board application. You will be able to add phot

Hello iCoders. This is a follow up post to my initial post on the Assets Library Framework and Blocks. We came across an interesting problem when working on the application for . They have had an since the very early days of the app store, and one of our biggest struggles has been creating an interface to allow users to select multiple photos from their photo album for a slideshow. While the iPhon

As many of you may have seen in recent weeks, Twitter changed its access policies and now that access Twitter user accounts. This is a large change from how many iPhone developers having been incorporating Twitter into their applications. What is OAuth exactly? How can iPhone developers get their apps up to date so they don’t break their Twitter incorporation? Well we have all the info you need to

Way back when, when everyone was still complaining about Apple’s lack of support for (3rd party) multitasking, there was a simple solution put in place. This solution was known as push notifications. Push notifications solved many of the issues associated with background processing. For example, when quitting the AIM application, the server could keep you logged in and send you a push notification

iOS 4 presented a million billion new API’s by Apple’s count, but for this post I am going to show a quick demo of the new Assets Library API where you can now get to users photos and videos with more access than ever before. This new API relies on the new programming device called Blocks that has been introduced with iOS 4. Blocks are used through many of the new API’s as a kind of extended @sele

Introduction Now, that the iPad has been released, I’m sure you are all scrambling for ideas on how to snag a piece of the maket in the imminent gold rush. iCodeBlog is going to help you on your journey with a series of iPad tutorials to come. Since the iPad uses the same SDK as the iPhone, all of the code under the hood is almost identical. Actually, when looking at the , you will realize that mo

If I need to predict one thing about where the App Store is heading to, now that the iPad has been released, I would say “It’s going to be less about farting apps and much more about productivity apps” Yes – the iPad has already changed the game drastically – with an almost real life size keyboard, large beautiful screen and file sharing direct in iTunes you can achieve much more than before. But

Introduction So, let’s face it, MANY applications in the app store are “Clunky”. They have jittery interfaces, poor scrolling performance, and the UI tends to lock up at times. The reason? DOING ANYTHING OTHER THAN INTERFACE MANIPULATION IN THE MAIN APPLICATION THREAD! What do I mean by this? Well, I am essentially talking about multithreading your application. If you don’t know what is meant by m

Introduction Back in July of last year. Brandon put up a post showing you how to integrate twitter into your application. Today I am going to take the class he made last year and add a new class which will let you post to twit pic. First lets do a little overview of what tools we need for this. Required Tools Twit pic is an awesome service. They have created a whole public API, that anyone can use

I had some a to shorten URLs for an in-application Twitter client I’m working on and thought I would share my simple solution with you guys. It’s actually pretty straight forward and can be done in 1 line of code. I have broken it up into several for clarity. NSString *url = @"http://brandontreb.com"; NSString *apiEndpoint = [NSString stringWithFormat:@"http://api.tr.im/v1/trim_simple?url=%@",url]

I was recently working on an internal project for Burnside Digital, and decided it was time to do some memory profiling to make sure that I didn’t have any leaks. I ran the program with the ‘Leaks’ tool of instruments, and as I was watching the Live Bytes column, I saw the number of Bytes being used, slowly but surely increasing as time went on. Instruments wasn’t detecting any leaks, so I knew th

I’m sure you have seen a Twitter client such as or count down the characters as you type your Tweet. This is done by responding to the Editing Changed action on a UITextField. Today, I will show you how you can implement this functionality in your application as well as show you some other real world examples of responding to this action. Here are a few of the uses that we will discuss: Countdown

The UITextField is probably one of the most commonly used UI controls on the iPhone. It is the primary method of user input via the keyboard and provides a great deal of additional functionality. With the success of our las API tutorial on NSArray, I thought I would do another walkthrough, this time on UITextField. I will be explaining all of the properties for it as well as bringing up some funct

A lot of applications you see have an email button. When you click it then it will leave the application and take you to the Mail application. It can get really annoying leaving the application and then going back in after your done sending the email. This is just a great way to show off your app and make your app look more professional and make it easier on the user by filling in the To and Subje

This will be a simple tutorial showing you how to put a UITextField in a UIAlertView. This is simple and just a couple lines if code. You will learn CGAffineTransform and coding UITextField programmatically. Heres a screenshots of what we should get. So lets go ahead and get started… 1. Create A New View Based Application You can name it whatever you want, I am gonna name it TextFieldInAlert. 2. I

If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting! Hello everyone. Welcome to another screencast. Today we will be looking into the MapKit, a new API’s made available by Apple in the iPhone OS 3.0 release. The MapKit allows simple access to the map seen in the maps application. Using GoogleMaps as its engine the map kit allows for a developer to make their own custo

Introduction Hey guys. This post is in response to a comment made in my last post about NSTimers. Techy asked if we could do a post on how to take screenshots programmatically using the iPhone SDK. For this minor project we will be creating a small web browser application that will start at www.google.com, and have a button on a toolbar at the bottom to take a picture of the web view and save it i

One thing I have noticed about many of the games in the app store is they lack animation. Of course, the huge companies like Sega and PopCap have some pretty amazing animation, but what about us indie iPhone game developers? Well, Apple has made it quite simple to do animations. I really feel this method is often overlooked. I will show you in just a few lines of code, how to completely animate yo

If you are a developer (which you most likely are if you are reading this) you probably have (or should have) a Twitter account. With Twitter getting so much attention lately, you would be crazy to not include some sort of Twitter integration into your own iPhone application. There are many ways applications can be made more social by including Twitter. For example, you could make the application

Hey everyone, welcome to my first of many screencasts coming in the next few weeks. Today I am going to show you how to layout a UITableViewCell in Interface Builder and have a UITableView populate with those type of cells. I am adopting a new structure for my screencasts which will be 5 or so mintues of keynote slides giving background info followed by 20 – 25 mintues of step by step development.
