Drag problem in Facebook layout type. #50

Hi, first of all, congratulations for the wonderful uicontrol. I've used several times your switch, no problem. But now I have implemented it in a Facebook layout type, a draggable view. When move the thumb, arrives in the middle and come back. With a single touch does work.

You know how to solve this problem?

Thanks man

It's hard to visualize the problem you're describing. Can you post a video describing the issue? That would help.

Hi, sure. Sorry for the mess inside the view: P

Nice implementation of SVSegmentedControl...

It looks like the touch is getting cancelled somehow. Don't really have the time to recreate your setup, but here are a few clues:

Have a look at the Tracking in SVSegmentedControl.m
Add breakpoints to see what's going on.
Another thought is that the segmented control drag gets cancelled by the facebook layout type view. Just like a UITableView will cancel the touch of a cell when you drag it by enough pixels. Perhaps there's a similar property, like canCancelContentTouches on the facebook layout class?

Thanks, tried to experiment and let you know. I have only one doubt, I do not think the problem is in the layout, because I have other uicontrol inside, and do not have this problem.

You're right, if there's no problem with your UISwitch then there shouldn't be a problem with SVSegmentedControl. It's probably something in one of the tracking methods then...
