DaisyChain

DaisyChain is a micro framework which makes UIView animations chaining dead simple. It uses the exact same interface you are familiars with.

Chaining made simple

We all have seen or written code which looks like this:

UIView.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(0.0, 0.0)
  }) { _ in
    UIView.animateWithDuration(0.5, animations: {
      view.center = CGPointMake(100.0, 0.0)
      }) { _ in
        UIView.animateWithDuration(0.5, animations: {
          view.center = CGPointMake(100.0, 100.0)
          }) { _ in
            UIView.animateWithDuration(0.5, animations: {
              view.center = CGPointMake(0.0, 100.0)
              }) { _ in
                UIView.animateWithDuration(0.5, animations: {
                  view.center = CGPointMake(0.0, 0.0)
                })
            }
        }
    }
}

This can go pretty far, it is also know as the callback hell. It's not very flexible and hard to read.

With DaisyChain the above code looks like this:

let chain = DaisyChain()

chain.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(0.0, 0.0)
})

chain.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(100.0, 0.0)
})

chain.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(100.0, 100.0)
})

chain.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(0.0, 100.0)
})

chain.animateWithDuration(0.5, animations: {
  view.center = CGPointMake(0.0, 0.0)
})

As you can the the code looks more flat, it allows you to easy modify orders or add new steps.

Breakable chains

DaisyChain also adds a simple way to break animation sequences, simply set the broken property to yes to break a chain:

chain.broken = true

To continue chaining animation, you'll need to put it back to false or create a new chain.
