Windows & Views
have a few questions about windows and views that I hope you people can help me work out!
Googled around for a while but without much luck=(
1. Is there a simple way to prevent the system to send more then one touches to a view based on it's super view? Say I have to buttons in one view and I don't want the user to be able to press them at the same time. So when the user press one button It tells the super view that other sub views should not be able to receive touches from now on.
2. Is there a nice way to cancel touches programmatically? When one view gets focus I want to cancel all touches that belongs to views further down in the chain
3. I've made a setup for landscape mode but even though I have to transform all views belonging to the window, why is that? (I tried to transform the window at startup it worked for the views but 1/3 of the screen couldn't receive touch events anymore) so is there a way to setup for landscape mode without having to do transform all the sub views?
4. One part of the screen in my app should be updated frequently and I am therefore planning to use openGL ES for that part only and Core animation for the rest is there any disadvantages to mix them?
Thanks in advance!
