Has <ListView> infinite scroll and pull to refresh?

[danicomas]

If the answer is YES. Anyone can give me an example?

[colinramsay]

I believe the answer is NO 😞

Possible duplicate of: #121 ?

[danicomas]

OMG It is a basic component :S

[colinramsay]

Which is open source and available for improvement!

[ide]

It does have infinite scrolling (look at the data source code) but a refresh control is separate. ++@colinramsay, it's all open source so build what you need.

IIRC, refreshControl is somewhat tricky to get working correctly outside of a UITableViewController.

Please see #502 for pull to request

Is it correct to use the event onEndReached for infinite scroll? I don't like because I need to have an array in js memory. :S

A good example about how I can paginate the listview? @vjeux

[danicomas]

If I use this onEndReached in iOS simulator works great but in iPhone 4 the scroll sometimes causes a lazy/strange effect. It is posible a memory problem?

Look this video with simulator iphone 4S iOS 7.1:

And this with physical iphone 4 iOS 7.1:

@danicomas check it out, it may help you #499

[bluemsn]

+1 , @danicomas I also found the problem. and did you fix it ?

[danicomas]

I have been disconnected in React the last month I can't help you sorry @bluemsn but I will try it again soon.

[khacanh]

I'm late to this, but it may help others, I created a demo project for pull-to-refresh and endless scrolling here https://github.com/CodeLinkIO/ReactNative-Endless-Scrolling
