Today, HTTP requests are used widely in websites as we fetch data using APIs, get screenshots or AJAX requests.
Unirest is a pack of lightweight HTTP libraries for many languages (PHP, Ruby, Python, Java And Objective-C).
It has support for GET, POST, PUT, UPDATE, DELETE operations and its methods + response structure are the same in all languages.
The usage is very simple and straightforward. Also, it is documented well.
When developing something in a language that you're not so experienced with, looking for the examples and digging them deeply is a good way of learning.
Same with the iPhone application development and considering it is something new for many developers, viewing the codes of real-world applications and re-using them when needed is very valuable.
Here are 20+ open source iPhone apps to learn and get inspired from:
The official WordPress application for iOS.
Besides strong content or comment editing features, it can share your location while publishing a post as well (download exists under the "development menu").
The open source iPhone application of the FreshBooks invoicing service.
It connects to the FreshBooks account and enables you to use most of the features (source is offered here).
An e-mail search application (acquired by Google) that downloads all your e-mail and makes full-text searches.
iPhone is rapidly mobilizing internet users & creating its own standards.
At the time this post is written, there are millions of iPhones in use & numbers are increasing really fast. So, it is becoming very hard to stay in-compatible with it.
There are 2 main ways to deliver your content / product into iPhone:
The major differences between them are, an application can use all the iPhone features (like sounds, movements…), work offline where a webpage cannot (technically yes but it is not functional) and an application can be sold / distributed via the iPhone store.
Tools that are must when creating for iPhone like the SDK or the optional ones that you’ll find very handy.
The main & official source for creating iPhone applications. It provides great & very detailed information & iPhone SDK can be downloaded from here.
Free membership is required for reaching the content. To download development tools like Xcode & distribute your iPhone apps via the store, you need the pay for it.
PhoneGap is an open source development tool and framework that allows web developers to take advantage of the powerful features in the iPhone SDK from HTML and JavaScript.
iPhoney, powered by Safari, gives you a pixel-accurate web browsing environment that you can use when developing web sites for iPhone. It’s the perfect 320 by 480-pixel canvas for your iPhone development
A web based application that enables you to test the look & dimensions of iPhone applications.
A very functional iPhone UI library. It aims to turn standards-based HTML into iPhone compatible interfaces.
To give an example: it transforms <a> tags into sliding interfaces rather then opening a new page. You can read the introduction of the author & see an example (digg for iPhone) created with it.
