I want to create a scrollview with a zooming control and a button next to the scrollbar. Sort of like the "tile window" button in XCode (top right corner of the editor), it should be in the same box that usually is used by the scrollbar only.
Do you have an idea of how to approach this?
I was thinking to use an NSScrollView and set the scrollbars to a custom subclass of NSScroller which includes the other widgets. What kinds of buttons use the same style as the scrollbar?
Subclass NSScrollView and override -tile. You'll add the subviews on -init... or nib awake (or some other convenient time) and lay out the controls manually in your overridden -tile method. If you call [super tile] first, then adjust the bottom or right scroll bar to make room for your custom control(s), your job will be a lot easier.

I need to achieve effect of my button like this:
My questions are:
How can I add this custom shadow to button, so only 'BUTTON' surface reacts for touches?
When I have the next button in the bottom, close to previous one, how can I be sure that it will not be covered by upper's button shadow?
I need to have all the buttons in front and all the shadows in the back.
If you want to add the shadow without having it clickable, you need to add an imageView to as a subview to the button. (make sure clip subviews is disabled).
If you want the shadow of one button not appearing on top of the other, then you need to have the shadow(s) added separately to the main parent view. The solution in option 1 will not work. Its not neat, but its the only way i can think off.
in my iPad application I have a panel of buttons, I have used an UIImageView as this panel and put buttons on top of it and created my nib file. in some views some button of this panel should not be displayed. so what i do is removing those buttons and decreasing the height of the panel (a UIImageView) then reposition the button to take up the space of the removed button. I have created outlets to all of these.
Is this the way to do this? My problem is if I want to change the order my buttons are displayed at some point I can't do it by simply changing the nib file. I'll have to do some changes in the code as well.
In this case don't use the nib to position the buttons in the first place. It sounds like this is one of the occasional cases where you would be better off working solely from code.
Instead of having to worry about some sort of abstraction that protects your layout if you decide to reposition the buttons and about removing and repositioning buttons, you can just do the layout at runtime once your particular view knows what buttons it needs. Your code is already doing much of the work of layout already (removing and repositioning).
Is there an easy way to add scrolling to the contents of a NSwindow? as an example scrolling sideways on this window to reveal more space?
This is very easy using an NSScrollView. In Interface Builder just drag a scroll view into your window. Then you can embed whatever contents you want in the NSScrollView's view. In Interface Builder's Attributes Inspector of the scroll view you can set whether you want horizontal and/or vertical scroll bars.
At the moment I'm working on an iPad explore game which has a hexagon tile map.
I've created a UIScrollView that contains a background view (the game map) and buttons in the form of hexagons (for interaction). I add every UIButton to the view via addSubview.
But... when I add more than 100 buttons the view gets laggy (no surprise here). But what should I do to solve this?
Example:

Adding UIButtons isn't the way to go here. You should probably draw the "buttons" in a custom -drawRect: method and use -touchesEnded:withEvent: to decide what the user wanted to do.
I would like to have something similar to the "List mode" of the stacks in the Dock.
But it should have the behavior of NSPopUpButton, in terms of displaying the selected object still, when the "drawer" is collapsed.
Each row should contain an image and to text columns.
How would you realize this?
Maybe subclassing NSPopUpButton, to display a CollectionView?
Or having an ordanary button and attaching a window containing a CollectionView to it, when clicked?
Oh and this up and down bars, instead of scrollbars on the side - how's that done?
Why not use a regular NSPopUpButton whose menu assembly is replaced with subclassed NSMenu/NSMenuItem that draws things the way you want? You get all the scrolling behavior for free.
If you insist on using NSCollectionView, however:
1 - Don't subclass NSPopUpButton if you're planning on popping up anything other than a menu. It's built to display a menu. Just use a regular NSButton and manage its -state (NSOnState while the collection view is displayed; NSOffState otherwise) manually.
2 - You could show a borderless transparent window (many examples available online) with a standard collection view / scroll view assembly minus the scroll bars. The borderless window could host the up/down areas (which can be simple views with NSTrackingAreas to detect mouse over). These areas could manually scroll the NSScrollView a bit every n milliseconds using an NSTimer while hovered.
