问题
I'm using the XCode 4.2 beta (build 4D199) on Lion, and can't access the Developer Documentation in XCode 4.2 anymore. When I attempt to log-in, I get a pop-up telling me the (remote) file is "locked", in the fashion that Lion does these things.
Does anybody have a suggestion what I can do to access the documentation from within the Organizer? I used to be able to access it without any issues, not sure what changed.
回答1:
The situation was fixed for me by Apple / XCode itself, as it automatically downloaded the (newly available?) "iOS 5.0 Library" documentation files. Documentation now runs from a complete local copy.
To be sure you get this too you need to have the automatic download of documentation files turned on.
Preferences > Downloads > Documentation > Check for and install updates automatically
(You can also download the files manually by clicking on "Check and install now")

Same here. To work around this issue, right click on the sign in page and choose "Open Page in Browser". This will open the same resource in Safari.

1.- Download library from: http://developer.apple.com/rss/com.apple.adc.documentation.AppleiPhone5_0.atom
2.- Open with The Unarchiver
3.- Copy file in "Developer/Documentation/DocSets
4.- Open Xcode

Had the same problem. To solve it (well seems like that), i went in
Xcode -> Preferences -> Downloads -> Documentation
Download the parts you need, for me it worked.

As other commenters have stated you should be able to fix these problems by downloading the documentation again. However, given that a complete set of iOS & MacOS documentation clocks in at around 2.0GB here is an alternative method that avoids re-downloading.
Jump to the documentation folder:
cd /Library/Developer/Shared/Documentation/DocSets
Recurse through all the documentation sets and set the current user as the owner:
for f in *.docset; do sudo chown -R $USER $f; done
Unlock the documentation sets:
for f in *.docset; do SetFile -a l $f; done
N.B. Your documentation path may be different (check ~/Library/...), you should make sure that $USER is correctly set to your username, you will need the root password
