draw line between UIImageViews

[kieran12]

Hey everyone, I've been trying to figure this out for a while now but haven't got anywhere.

When a user touches a uiimageview and drags to another UIImageview I want a line to be drawn connecting the two uiimageviews. I cant figure out how to do it.

Can anyone help me please?

Thanks in advance

You could consider a transparent view that covers them so you could draw over the top but you'd want to forward touches to the other views.

I think I saw that in one of the tutorial vids. So I would have one view that is drawn on and when the touches end the line is transferred to the view holding the uiimageviews and the transparent top view is cleared?

All depends on your app and what you need to do. Do you need the line to stay on top at all times? Can you calculate where the line should be in subviews, etc.

The line will be visible at all times but once it is drawn it will not be modified. The lines drawn between two images will be straight. Each users line will be drawn in their color and once a user draws a line between two images no other line can be drawn over theirs.

Thanks for your help scott
