Instead, Xcode 4 has a debug area with log output on the bottom of the main window. Because there is lots of log output in our projects and I don’t want to resize the debug area every time, I tried to reproduce the behavior of Xcode 3 (sort of).

For changes introduced in iOS 5 and iOS 6 including the deprecation of presentModalViewController:animated: see also this more recent post: Presenting View Controllers Modal View Controller Recap Modal view controllers are well documented in the View Controller Programming Guide for iPhone OS but here is a quick recap of how to present and dismiss a modal view. To keep things simple I will cover the steps for presenting the modal view when a button is pressed on a master view controller.
When the button is pressed we need to create and show a detail view controller that contains a button that the user can use to dismiss the modal view controller. Allocating and showing the detail view controller is straightforward: The target action of the button is the method dismissView in the detail view controller. Modal Presentation Styles. Web color to UIColor convertor. Introduction to iOS Graphics APIs: Part 1.
Download source code - 294 KB Introduction In the first article in this series, I provided a quick introduction to Objective-C, and talked a bit about memory management, working with the controls, and persisting information to files.
In this article, I want to introduce some of the graphics functionality. I will be using the iPad emulator as the target device for this article because of the much better display surface that it provides. But the APIs shown here will work on the iPad, iPhone, and iPod Touch. Prerequisites To take advantage of this article, you will want to have some familiarity with Objective-C and iPhone development. Available APIs The iPhone supports two graphics API families: Core Graphics/Quartz 2D and OpenGL ES.
Representing Colors There are several different ways to represent a color digitally. Show TODO's And FIXME's As Warnings In Xcode 4 - Deallocated Objects by Jake Marsh. Here's a neat little snippet for Xcode 4 that will cause all of your //TODO: and //FIXME: comments in your code to appear as compiler warnings when you build.
Here's how to use it: Instructions Head over to your project's item in the Project Navigator (usually at the very top)Find your target in the list of targets on the left, select itHead over to the "Build Phases" tab.Click the "Add Build Phase" in the bottom right of this screen.In the editor that appears insert the bash script shown below. Now just build and you'll see all your //TODO: and //FIXME: comments have become warnings. I love this technique, it might not be right for everyone, but hope it helps someone.

SBJson. SBJson’s number one feature is chunk-based operation.
Feed the parser one or more chunks of UTF8-encoded data and it will call a block you provide with each root-level document or array. Or, optionally, for each top-level entry in each root-level array. See more in the Version 4 API docs. Other features: Configurable recursion limit. Please see the API Documentation for more details.
The preferred way to use SBJson is by using CocoaPods. Pod 'SBJson', '~> 4.0.0' Universal Framework iPhone iOS (2.0) Hello my friends, Due to some bugs and questions with the old tutorial, I'm creating this new one, much more simpler and less bugs than the another one.
I'll not post the old link here because everything you need to know you can find right here. Cheat Code. iOS SDK 5.1 on Snow Leopard. 2 years ago So apparently Apple wants us to upgrade to Lion in order to develop for the latest version of iOS.
But Lion still has a few issues that are preventing me from upgrading. I quickly upgraded my phone to iOS 5.1/6.X not knowing that i wouldn't be able to use XCode with it on Snow Leopard. So the hacking started... It turns out all that is needed is a few files and an updated symlink. You can find the DMG for the latest XCode over here: after you download it, all you need to do is mount it, and run the following commands in your Terminal after those fixes XCode should allow support for the version of the SDK you are trying to use :), this may work for future versions too!
Using Blocks in iOS 4: Designing with Blocks. In the first part of this series, we learned how to declare and call basic Objective-C blocks. The motivation was to understand how to effectively use the new APIs in iOS 4 that take blocks as parameters. In this installment we're going to shift our focus toward writing our own methods that take blocks. ASIHTTPRequest Documentation - All-Seeing Interactive.
ASIHTTPRequest is an easy to use wrapper around the CFNetwork API that makes some of the more tedious aspects of communicating with web servers easier. It is written in Objective-C and works in both Mac OS X and iPhone applications. It is suitable performing basic HTTP requests and interacting with REST-based services (GET / POST / PUT / DELETE). The included ASIFormDataRequest subclass makes it easy to submit POST data and files using multipart/form-data.
Features ASIHTTPRequest comes with a example applications for Mac and iPhone that demonstrate some of the features. ASIHTTPRequest is partly based on code from Apple’s ImageClient code samples, so if it doesn’t meet your needs, take a look at their CFNetwork examples for more. ASIHTTPRequest is compatible with Mac OS 10.5 or later, and iOS 3.0 or later. iPhone SDK Examples and Tutorials - About Objects. iOS SDK Examples and Tutorials Download our iOS developer examples. Feel free to download any or all of the example code for the Xcode projects shown below to aid your learning. You can even incorporate the code in your own iPhone and iPad apps if you like.
