guys. I am a newbie at Objective-C programming. I was wondering if it is possible to make an image that a user can pick from an image library on their phone. I already have created a UIImageView in the storyboard and a UIImage in the code. How should I do this? Thanks in advance.
Yes, have a look at the UIImagePickerController class and set the source type to UIImagePickerControllerSourceTypePhotoLibrary

Can I pass an Image from a popoverview to the controller that brings the popoverview forward? Can I pass the image with a delegate or do I have to put it in NSData to transport it?
I am having struggles with it, I already tried a thousand tutorials but I can't get it working, so my question is:
Is it possible to pass images from popoverviews to viewcontrollers?
And, if yes: what is the easiest way to understand and do this?
I have an NSOutlineView and a stack of objects, you can imagine it is a tree of files.
So I tried to extend the NSTextFieldCell class to parse the name of the current item and render an icon for it. But I am still stuck in the icon part. I simply can't get a standard-hardcoded-image to work!
I tried many tutorials, the only one I got to work is a class called PXSourceList, but it was designed for OSX 10.7+. Also the majority of these tutorials use AppDelegate with the NSOutlineViewDataSource protocol and I also want the code to be managed elsewhere, not in the APPDelegate class.
Can someone give-me some directions on the first steps? I think a bit of enlightenment on how the general logic surrounding the icon thing would be enough. I appreciate!
I use XCode 4.2 for Snow Leopard. The project I'm on is supposed to work in OSX 10.6+, so I can't use the new Lion approach of cells using NSViews.
You can get the file icon from its path as follows;
NSImage *iconImage1 = [[NSWorkspace sharedWorkspace] iconForFile:filepath];
You need an image cell to display the icon image.

I need to display the contents (data) of this array into a window (tableview or else don't care) the only problem is that the data is not static so i can't fix n labels if you understand me.

Follow the documentation and you should solve your problem.

I have a question regarding the several images and sound files in the Media tab of IB's library: how can they be used in code?
I want change the image of a NSImageVew to NSRevealFreestandingTemplate, but how can I access it? I'm pretty sure there must be a better way than creating a hidden image view and pulling it from there. Any ideas?
Thank you!
Use NSImage's imageNamed: method to get system images. You can use any of the values found in NSImage's Constants section as the name. To get the image you specified, you would use:
[NSImage imageNamed: NSImageNameRevealFreestandingTemplate];
[imageView setImage:[NSImage imageNamed:#"NSRevealFreestandingTemplate"]];
