I've got a Mac project i want to port to IOS but i cannot resolve some classes.
there is no header file included in the source except Cocoa.h which Ios does not
use. What is the method to find the right header file or framework?
The classes are SecExternalFormat, SecExternalItemType and SecKeychainAttrType
The first thing I always do is a Google search. For example, in your case I might have done:
site:developer.apple.com SecKeychainAttrType
That yields this page, and then you know you need Security/Security.h.
If you downloaded the documentation (I think it comes with Xcode) you could also search it offline.
As for why the API has changed, I think that's beyond the scope of your question.

I am currently trying to analyse Bugzilla in order to find the ratio of number of bugs : lines of code for each Firefox component. However, I have never worked with Bugzilla before and have no knowledge of Firefox's codebase.
How would I go about finding lines of code per Firefox component (as they appear on Bugzilla under Comp header)? I have made an attempt at looking through mozilla central, but have no idea which source files relate to which components.
EDIT: Dexter pointed out that there is a directive BUG_COMPONENT in the mozilla-central tree, but this directive seems extremely incomplete and is not helpful. Any other advice, or pointers as to where I could get such advice would be much appreciated.
Great question! We recently added the BUG_COMPONENT directive (see the meta bug) to the Firefox code: it's in the moz.build file contained in each directory in the source. This directive allows linking each file in the repository to the related Bugzilla component.
For example, the following directive found here, tells that all the files in test/browser containing the Telemetry word belong to the Toolkit::Telemetry component on Bugzilla.
with Files("test/browser/*Telemetry*"):
BUG_COMPONENT = ("Toolkit", "Telemetry")
You can use either DXR or searchfox to quickly search the Firefox repository.
Updated the answer to account for the questions in the comments.
As noted in the comments, some components are tracked on Bugzilla (e.g. Activity Stream) but do not have a direct mapping to source files within the mozilla-central repository (the one Firefox is built from). That's because some newer components do not ride "the trains" (~6 weeks development cycle), but are rather updated more frequently and deployed as addons.
The code for these components usually lives under the Mozilla github account, along with other project. Since there are quite a number of projects, one way to identify the ones you might be interested in is to restrict them to JavaScript ones. If you follow this last link, you'll see the repository for both the test-pilot and Activity Stream (plus other addons).
I'm afraid the only way to match GitHub projects to Bugzilla components is to look at the name of the repository on GitHub and find the matching component in Bugzilla: you can type the name here to get some component suggestions. If you want to get fancy, you might also leverage the Bugzilla REST API:
Get a list of the JS GitHub project.
Extract the name of the project.
Use the REST API to get the component suggestion.
I would personally just consider the mozilla-central repository as a starting point, as it is mostly annotated: scrape the BUG_COMPONENT from the source files, map them to the paths then use the REST API to get the list of bugs.
Sidenote: the Download Panel seems to be correctly annotated in the main repo.
We're using octo.exe to create releases. It starts suddenly giving error saying can't find project. I checked the api/projects and that's true, it is not in the returned json response. But when I look at the dashboard I can see the project. The only thing I did was cloning another project from this one earlier. The cloned project is working fine but not the original project.
It exists in dashboard (web gui) but not in api (hence octa.exe can't find project)
Looks like api is caching the projects. The new projects that I created via GUI not available in api.
Thanks,
I have had the same issue yesterday. It turns out to be something interesting. I believe that your project is still there properly set, but the total number of projects that you have become more than the listed ones in the API, and that's why the Octo.exe couldn't see it anymore.
I have explained here, how I managed to fix that issue quickly.
This is due to how pagination is implemented in Octopus (pretty poorly if you ask me). But you can override it. add this to the URL (at the end).
'?skip=0&take=2147483647'
alternatively, you can watch the json returned, if you find the links.Page.Next property you can use that link to get next page of the api response.
I noticed since Xcode 4.3, the audio unit templates are gone and the audio unit headers and helper apps are a separate download from Apple's website.
I have no idea what to do with the downloaded folder... I tried putting AU Lab And HALLab in Xcode.app/Applications and they don't show up in the new developer tools menu; I tried placing the CoreAudio folder with the headers in Xcode.app/Developer and even recreating /Developer in my root and Xcode doesn't see AUEffectBase.h anywhere (unless I actually add the file).
I saw someone's post on how to come up with a new from-scratch template but I won't even go there yet since Xcode doesn't even find the headers right now.
Any ideas on how to go about making it all work again?
And about the templates.. I can forget about them right, meaning, the ones we used to have from Apple?
Thanks!
If they are in your project, and referenced by Xcode, then you will have to update those project references. Xcode may refer to them as absolute path, relative to project, relative to SDK and a few others.
At this point, you might consider creating a static library for these dependencies, if you have multiple AUs to build out. Then you just create a static lib to link to, rather than managing a handful of sources per AU.
Templates: It appears they have been removed (temporary? permanent? idk). I moved off distributed template dependence years ago. Perhaps you can scan or hit the CA-API list and see if a dev has one handy.
I know some of the tutorials for creating Xcode project templates, for example this one here: http://robnapier.net/blog/project-templates-364
This is the best one I could find. All others basically repeat the same info, or are no longer up to date, or worse tell me that even they don't know what they're doing. Possibly useful tools that are linked to here and in other places are no longer available.
I keep running into roadblocks, and would like to gather as much information as possible on the process of creating Xcode project templates. Info that is most importantly up to date (at least it must be relevant for Xcode 3 or higher).
For example, what I'd like to see is:
a description of the
TemplateChooser.plist and similar
plist files and what these options do
(in my case, once I add a
TemplateChooser.plist, my project
disappears from the Xcode project
template list)
how to create a project template that references another .xcodeproj (when I do that, the other .xcodeproj appears in the project template list even though it doesn't use the special naming convention)
processes that can be applied, for example is it possible to run a script during the creating of a project from a template? This would be useful to unzip certain files into the newly created project.
If you have the answer or suggestions to any of the issues above, I'd appreciate that. Otherwise any link to good Xcode project template resources would be highly recommended. Especially if there is an official documentation from Apple - I haven't found one yet which seems to imply that project templates are undocumented.
Have you seen these:
http://www.sodeso.nl/?p=895
http://www.codeproject.com/KB/iPhone/CreatingXcodeProject.aspx
If you say you have searched, I'm pretty sure you've already seen the links but these are the best resources I could find with my 'googlabilities'
You might try contact this guy - http://linkedin.com/in/mottishneor he has some related messages around the web
The links suggested by FX are also not bad at all!
There is indeed little XCode template info out there. What I have found of interest are the following links (I documented myself on the topic, but haven't yet gone any further):
a Google Code search reveals a few examples, but not much
in particular, I found interesting to look at the code provided by Three20; they have some basic examples, like here
referencing another project worked for me, so maybe you could open a specific question about that giving more details?
there is information scattered on the Apple mailing-lists
there is no official documentation from Apple, as is evidenced by the lack of results to this query
I'm sorry if this is not a Enlighting, concise answer. As you said, it's not well documented, and sources are all over the place. I just hope I could highlight some places to find information that your own searches might not have reached :)
I don't have a Mac anymore, so this is as much as I can give you without testing this myself. As far as I can tell, Xcode templates are undocumented by Apple.
This guy has some guides for messing with Xcode templates but the info is pretty sparse. My suggestion for working with templateChooser.plist is to try to only edit that file in the interface builder.
This guide is a good example of how to add a reference to another .xcodeproj. For the reason you were having trouble adding a reference to your project we probably need more information.
If you scroll way down in this doc you can that each template already includes a script called myscript.sh. This script will show up in the scripts menu for projects built with that template. That isn't quite as convenient as running scripts automatically, but it's better than nothing.
In conclusion, Xcode template documentation is a nightmare. It looks like there are a lot of powerful features there, but they are obscured because of lack of user friendlyness and because documentation lags far behind Apples updates of Xcode. It just doesn't seem to be a priority for them. I hope this helps.
And yet another video link http://howtomakeiphoneapps.com/2010/10/how-to-make-custom-xcode-templates-with-video/
I have searched my entire Mac for ibplugin to find the QTKit IBPlugin, but I also came accros a plugin which adds AFAssistantPane to IB. I did a Google-search but Google has no results for it. So, does anyone know how I can use this AFAssistantPane?

Update: I noted that this is in a private framework (that's why it is not documented).
Update: The framework doesn't include header files. Must I hack it and recreate the header files?
There is a command line utility for exploration of private frameworks called class-dump. You can google for it. Here's the first result that came up for me: Dumping the iPhone 2.2 Frameworks.
