Window blocks on execute Cocoa

Question

My problem is that my application's window blocks when I raise a method that represents values in a NSTableView. I want to do an animation with a NSProgressIndicator (spinner), but my window is blocked and spinner doesn't show animation. I want if anybody can give me any hint? I thought in threads or something like this, but I'm not pretty sure how to solve this issue.

Answer 1

You're right, you need some kind of multithreading. Fortunately, it's rather easy to do simple operations on threads in Cocoa.

You should look into NSOperation and NSOperationQueue.
