NSTimer with anonymous function / block?

Question

I want to be able to schedule three small events in the future without having to write a function for each. How can I do this using NSTimer? I understand block

Answer 1

It's pretty easy, but it isn't included in Apple framework, not yet at least.

You can write a block-based wrapper for NSTimer yourself, e.g. using GCD, or you can use existing 3rd-party libraries like this one: https://github.com/jivadevoe/NSTimer-Blocks.

Answer 2

I have created a category on NSTimer witch makes it possible to use it with blocks.

You can actually call:

NSTimer.scheduledTimerWithTimeInterval(ti: NSTimeInterval,
                    target: AnyObject, 
                    selector: #Selector, 
                    userInfo: AnyObject?, 
                    repeats: Bool)

Use it like this:

NSTimer.scheduledTimerWithTimeInterval(1, 
                    target: NSBlockOperation(block: {...}), 
                    selector: #selector(NSOperation.main), 
                    userInfo: nil, 
                    repeats: true)
