[Feature Request] React style component Lifecycle hooks

[jewilhel]

I was reading through the React documentation and they talked about adding lifecycle hooks to a class: https://facebook.github.io/react/docs/state-and-lifecycle.html

with componentDidMount()
and componentWillUnmount()

These component methods would be very handy in addition to the willUpdate() and didUpdate() methods already available.

For example, I want to trigger animations when I create and present a component to the screen and also I want to trigger another just before the component is removed.

Thanks for your consideration! :)

On it :)

Oh, wow! I'm excited for this. This will make deploying animation so much easier! Thanks you!

Fixed in 4.9

See the AbsoluteLayoutExample for an example of the api use.

Man this is great. Had a look at the example code, looks easy enough. Can't wait to try it out. Thanks so much Alex this is so helpful! 👍

Hi Alex,
I did some testing of the new method didMount() in my components after studying your example in the demo project and discovered that the method doesn't get called in child components that are nested in parent components. Apparently, the method only works if the component is the Root node of the ViewController. This doesn't seem helpful beyond the base node of my view hierarchy.

Thanks for taking a look at this! - Jason W.

will take care of it and propagate it to children

Thanks so much Alex! :)

I'm also curious if the WillUnmount() method is too challenging at this time? :) I know you're super busy, I'm just interested in what you think about that one. If its practical or not. I've been trying to figure out how to implement similar functionality myself! Just haven't come up with good ideas.
