picture is a bit grainy, but it looks like it might be okra....Do you live in the south?

The picture quality is fairly poor, but from what I can see, those look exactly like radish seed pods. The four-petalled purple flowers would match radish, too.
The problem is, radish is not a vine. When it flowers, it sends up a stem 1-2 feet in height, which can have lots of smaller branches on it, with multiple flowers on each.
Are you sure you aren't mistaking two different plants growing close together for one single plant? Alternatively, radish stems can sometimes flop over and start growing sideways, so maybe you are mistaking that for a vine?
Try crushing one of the green pods and giving it a sniff. It should smell radish-y, or slightly cabbage-y or mustardy.
If it smells of cabbage and/or mustard then it is definitely a brassica (the family of crops which includes radishes, cabbage, broccoli, etc.) of some sort, and all brassicas are at least edible (though not all are that good to eat).
If they actually are radish pods then they are tasty and crunchy, and go well in a salad (like the root, they are best eaten raw).
