[Install, download, version, instance, offline documentation, and other information about the iPhone OS SDK]

When using the iPhone SDK for the first time, if you do not know the relationship between the version and the operating system, it will waste a lot of time to download and install the SDK.

The following summarizes some common methods and references that can be used as soon as possible.

SDK Installation

Remember to select the version that matches your Mac OS system. The download package is large and it takes a long time to download it in China. If the selection is incorrect, the installation will fail, for example, the latest ios sdk 4.2 requires the Mac OS version 10.6.4.

 

Mac OS upgrade policy

Product updates with minor version numbers can be upgraded free of charge. For example, products of the. * series can be upgraded free of charge. You can automatically download and update the updates directly on the main menu and software upgrade of the system.

However, a major version requires a fee upgrade. For example, you cannot directly upgrade the version from version 10.5 to version 10.6. You need to pay for the upgrade.

If you do not release the software to the appstore or development stage, and do not use the latest new features of the SDK, you do not need the latest SDK temporarily. Otherwise, it is troublesome to quickly upgrade the SDK.

Which version of the ios sdk I shocould use

Appstore only reviews the software of the last two versions, so it is not a question of which SDK we want to choose

View documents offline

When viewing documents in xcode, you can connect to the Apple site for viewing at a slow speed. Therefore, it is better to download the documents for more convenient viewing.

Official update super slow, refer to download this method of http://www.cocoachina.com/iphonedev/sdk/2010/1102/2281.html
