Information Technology Reference
In-Depth Information
The iOS and OS X reference libraries, which include documentation described in Chapter 6, are freely available
and do not require registration. The URLs change regularly, but currently you can find the iOS library at
ht-
tp://developer.apple.com/library/mac/navigation/
. If these URLs no longer work, search
for “OS X Reference Library” and “iOS Reference Library.”
Viewing developer videos
The developer videos, an example of which is shown in Figure 2.7, include keynotes and background talks, of-
ten taken from Apple's WWDC (World Wide Developer Conference) series. In the past, Apple charged $500 for
access to these videos. Now they are available via iTunes to anyone who registers for a paid program. The key-
note speeches from each year's WWDC remain free and can be downloaded by anyone.
Some developers find that the hands-on examples in the videos offer a more successful introduction to key
technologies and essential development techniques than the slightly chaotic explanations in the documentation.
The Mac and iOS Developer Programs allow access to different video collections. Only Mac developers are given
access to the Mac Development Foundation Videos. Similarly, only iOS developers are allowed to download the
iOS Development Videos.
Caution
Video sizes can up to 400MB, and the complete video collection is around 10GB. You can watch them online, but
if you have slow- or medium-speed broadband, downloading them may be your best choice. As of version 10.1 of
iTunes, batch downloading isn't available. You can mark any number of videos for download, but iTunes unmarks
them after it completes two downloads. The remaining videos must be reselected manually.
FIGURE 2.7
If you download developer videos from iTunes, you can back them up to an alternative location and play them in
alternative players, which may be on other machines.
