What are the IOS development technologies?

Software Development Kit (software development kit)

On June 65438+1October 65438+July 2007, Steve Jobs announced the software development kit in an open letter posted on Apple's website. It will be available to third-party developers in February 2008. The software development kit was released on March 6, 2008, which allows developers to develop and test applications for iPhone and iPod touch, and is called "iPhone Simulator".

However, the application can only be released after paying the cost of the iPhone development plan. Since the release of Xcode3. 1, Xcode has become the development environment of iPhone software development kit. The first beta version is iPhone SDK1.2b1(build 5a147p), which can be used after release.

Since iOS evolved from the kernel of Mac OS X, the development tools are also based on Xcode. To use the SDK, you need a Mac with an Intel processor and running Mac OS X Leopard. Other operating systems are not supported, including Microsoft's Windows operating system and the old version of MAC OS X.

The SDK itself can be downloaded for free, but in order to release the software, developers must join the iPhone developer program, and one step needs to be paid to get Apple's approval. After joining, developers will get a license, which they can use to publish their software to Apple's App Store.

There are three ways to publish software: through the App Store, through enterprise configuration, only among employees in the enterprise, or uploading to as many as 100 iPhones based on "Ad-hoc".
