Cocoa/objectiveC UI design issue

Question

I'm trying to build an app on MacOSX - ObjectiveC. I don't not find a good ressource to understand how I can create the view I need and the steps to made it.

I'm looking mostly to create 3 sections.

Section 1: Few buttons and one image Section 2: TreeView to have a File browser/finder Section 3: Progress bar to show the disk usage.

I'm creating an app to read android device and manage file transfer. Such as Android File Transfer.

Answer 1

First and foremost you need to look over the tutorial that Apple provides on creating your first Mac app .

Second you can use NSOutlineView to create your treeview, here's a tutorial on this.

Then you need NSProgressIndicator for your progress bar, here's a tutorial.

I also suggest you look over at ray's tutorials to get started with XCode and all the interface builder tools.
