how can i add a custom view to the right click menu of every file in os x finder?
e.g. i want to display the image if it is an image type and do some custom action etc.
is this possible with c or objective-c? if yes how? (without using any available tool)
You need to write a Menu Manager plugin based on CFPlugin. Unfortunately, this involves some really dated Carbon stuff. There is a tutorial from a few years ago at mactech
Note that this stuff may be obsolete with Snow Leopard, though whatever they come up with is probably going to be much easier to deal with than Menu Manager/CFPlugin cruft.

I am looking for a way to right click selected text and open it in my app. Eg. via OS X's third party share menu. But I can not find any references at Apple's.
Have a look at the apple docs SysServices for creating a service for you app.
The Docs take you through an example of how to set one up.
Once done you will need to go into System Preferences and Enable the service. Your users will also need to do that.
Here is a quick project that shows an adaption of the apple code.
Update:
Although I think the services work good enough. Creating a Share or Action Extension is possible.
This example uses the same Project as above. But I have added an App Action extension (Target) to it.
The template for the Action is not too hard to understand and it took me 5 minutes to do this quick example.
(So I am not saying everything is as it should be but it works)
For the Action Extension:
Follow the instructions here
Which basically is:
After you choose the extension point that makes sense for your app
extension, add a new target to your containing app. The easiest way to
add an app extension target is to use an Xcode template that provides
a target preconfigured for your extension point.
To add a new target to your Xcode app project, choose File > New >
Target. In the sidebar on the left side of the new target dialog,
choose Application Extension for iOS or OS X. In the pane on the right
side of the dialog, Xcode displays the templates you can choose
Do read the above docs to understand better of what you need to do.
Once you have added the Extension. You can actually run it straight away.
Xcode provides you an option to choose a test app to test it in i.e TextEdit.app and takes you through the whole process of temporarily enabling the Extension.
In this example, remember I chose an Action Extension which suited the App.
The App's function in life is to do a basic encryption of selected text and then display the result.
The App's Action Extension will do the same but instead of displaying it, it will replace the selected text with the encryption text.
All that was needed for me to do, was copy the encryption method from the main app, over to the Extension.
I did have to adjust a couple of things though. Namely the original code deals with a NSString, where as the Extension deals with a NSAttributedString.
The conversion I did works but styling attributes are lost. For this example that does not really matter.
An Action Extension does not use the Share contextual menu. It uses an Action menu.
To see the menu, select some text and the hover the cursor over the selected text. You then should see a discloser button on the left of the text.
Like this:
Click it and choose the Extension.
If you do not see it, go to the 'more' option. This will take you to the system preferences where you can grant access to the extension.
The documentation is mainly concerned about distributing the extension and App via the App store.
But you can code sign your App and extension and do a normal archive export.
From there, all should work ok with gatekeeper.
But again refer to the Docs for a fuller understanding.
Here is a link for the code signed app and also the new Project.

In Eclipse I could hit Ctrl+O and get a popup which I could use to get an overview of everything in the current class, pick an entry, and jump to it.
In idea, there is Alt+7, but I have a few issues with it. First, the keyboard doesn't seem to put its focus there. I have to take my hand off the keyboard and use the mouse to place the focus on the Structure dock.
I also don't like how it's taking up real estate. I don't want to change how things are laid out if I want to see the structure. I would like a more non-invasive popup, and handier and snappier.
Is there another feature that gives me quick access in the form of a popup preferably, like Ctrl+O provides in Eclipse?
Another nice feature would be to be able to use the J and K keys to move up and down the selection, instead of having to use the cursor keys. I'm using IdeaVim, so the normal workflow when editing files, is that both hands stay in a touch-type position. It would be nice if I can use the various navigation features also using vim keys...
Perhaps there is a way to enable this, that I haven't discovered yet?
IntelliJ equivalent of Eclipse's CTRL+O is CTRL+F12 (⌘+F12 on Mac), which will give you more or less the same pop-up as in Eclipse. But I'm not sure if it can be navigated using j and k keys.
More details can be found in the IntelliJ help.
First, I have xcode 3.4.3 installed on my hackintosh(10.6.5). When I started using xcode , I follow apple's steps from "Your First Mac App" tutorial. When I walked through creating actions for controls, it ask me to use the assistant editor to create connections between control and logic code, but I can't find anything called assistant editor is this because I am using xcode 3.4.3?
Could somebody please tell me some alternatives.
//edit: The assistant editor seems only present at xcode 4 and higher, so the tutorial you are using is newer than you current xcode version. Thanks #popeye for the hint.
The alternative is simply add the connections by yourself. You have to add the outlets in the interface-file (h-file) and the implemenations in the implementation-file (m-file).
There is a good tutorial video fromon how to achieve this:
Xcode 3 Recipes - Connecting an Outlet
Old Post:
The mentioned "assistant editor" is just a neat way to connect your outlets with your code. It connects the GUI with the code. For example if you have a button on your screen and you want to register a touch event on that than you can simply use the assistent editor to do that.
It is on the upper right corner of xcode. See the screenshot:
It shows you a split view with the code on one side and the Storyboard on the other. If you have that view open you can simply hold the control-key and drag a connection from the gui element to the code.
From the apple website: Assistant (): presents a separate editor pane with content logically related to that in the standard editor pane. Use the split controls in the Assistant pane to split the pane. Use View > Assistant Layout to set your preferred assistant pane and split configuration.
Apple iOS Developer Library - xCode Basics
I think you might be out of luck. I do not remember having an assistant editor in XCode 3, not like the version in XCode 4 anyway. Apple tends to keep it docs relevant to the newest release. The link provided by #palme is only relevant for XCode 4.
You might have be resigned to opening multiple windows to compare header and implementation files. In XCode 3, you will have to get used to mutiple windows at times, even seperate applciations (i.e. Interface Builder is completely seperate application from XCode 3).
I've a question. I cannot find the way, how to add buttons to main toolbar programmatically. My problem is, that I've the task to dynamically (based on XML configuration file) build menus and toolbar. I found how to add a menu item programmatically, but not toolbar button.
Tutorials mostly show how to create buttons and menus using plugin descriptor (plugin.xml), but not how to do it programatically. It seems, that it is out of bounds of Eclipse plugin philosophy.
I've just found this:
There might be layout problems with this approach. I also don't
believe the framework will try and re-create your dynamic item except
at random toolbarmanager updates. With Menus they can be updated on an
SWT.Show event, which is why CompoundContributionItem only applies to
Menus.
What shall I do? Can I say Sorry, there is no way to build toolbar dynamically. I can do it just for menus? Collegue says, that it must be possible, but he does neither know how.
The only way to be able to create main toolbar entries programmatically is in an RCP app, where you supply the ActionBarAdvisor for the workbench window. This isn't dynamic, however, just called on window creation.
Another way to do it would be to use org.eclipse.ui.menus and contribute org.eclipse.ui.menus.ExtensionContributionFactory. It also works only on workbench window creation (not really dynamic), but you could read your own XML and provide IContributionItems for the main menu or toolbar.
How dynamic are you trying to be? Most solutions work well on startup/window creation.

Whenever you try to do something programmatically in Eclipse that is normally done through plugin definitions you are walking on thin ice. I've tried it on a few occasions and it rarely ended up being easy or good.
Instead, think of what it is that you only know at runtime and need to be able to change on the fly. Is it the name or icon of the button? That can be changed at runtime.
Take a look at runtime commands, they can be confusing to define properly, but with them you can for example create buttons that are only visible if a condition is active. That condition could be set at runtime.
I am currently using xcode and I find it's lack of tabs quite disturbing.
I currently use command-shift-d to search through all the files, or ctrl-1 to open the history of files that were recently opened.
It works but I find it less effective than just tabbing through the few files i am currently working on.
Is there any way, third party or not, to enable some sort of tabbed organization?
If not, is there any other way to quickly navigate through a subset of files?
XCode 4 now supports tabs. You can enable by selecting "View / Show Tab Bar" menu.
Not really, but one alternative is View > Show Favorites Bar and drag five or six frequently-used source files into it. Not as flexible as tabs but satisfies your request for "quickly navigate through a subset of files".
The traditional way is to use the detail view. Get the files you want in the Detail view by one of these means:
Put them all in the same group, then select the group
Enter a filter expression in the Search Bubble that narrows the items shown
Define a Smartgroup that includes just the files you want
Get a list of the files as a Find in Project result, then select that item in Find Results
Then you can use the Detail View as your list of interesting files and navigate through it quickly with the up and down arrows.
First of all, you can use Textmate (which I believe has Xcode integration). Otherwise:
Window (Menu) -> Organizer (ctrl-command-o)
At the bottom of that window, if you don't have two panes, click the square to the right of the gear. Now drag code files of interest to the left, grey pane--a single click or arrow up/down will open the file in the editor pane.
If you do open a bunch of windows, as vog suggested, you'll need to command-~ through them--not alt-tab.
Cheers.
The Xcode source code editor allows you to choose the file from a list. It's two clicks instead of one (as it would be with tabbing), but it's better than nothing.
In addition, you can simply Alt-Tab through your open source code windows. This is not slower than tabbing, and has the same effect since the source code windows are usually placed exactly one in front of another.
You'll definitely want to read through this. (XCode Tips and Tricks you wish you know about two years ago - SO)
You can navigate between files using "Recent Files"
Write simple applescript:
tell application "Xcode"
tell application "System Events"
keystroke "1" using {control down} -- open "Related Files"
key code 125 -- choose "Recent Files" ("keystroke down" doesn't work)
keystroke return -- enter to "Recent Files"
key code 125 -- choose previous file
end tell
end tell
And bind it to some shortcut using for example FastScripts(free up to 10 bindings)
I have this script on "Control" + "`". (XCode 4)
Hope this will help
You may also try an Xcode plugin I've just released - it's called Code Pilot and solves a lot of issues of Xcode's navigation, making it more TextMate/Eclipse-like.
Check it out here: http://macoscope.net/en/mac/codepilot/
I hope this helps!
It is simple with XCode 7.2
GoTo View>>Show Tab Bar
This will show the tab bar.
RightClick on the New Tab and click -->"NEW TAB"
Then We can see all the files in tabs.
