Please do not post the same thing multiple times. The board software automatically flags certain posts as needing moderator attention. This happens the most often for new users. I'm pretty sure this is made clear at the time you attempt to post. Posting the same thing over and over again just makes that many more posts the moderators have to weed through later. This makes us sad. Don't make us sad. If your post/thread doesn't appear, just wait a while. Don't post it again. If it hasn't shown up by the next day, then you can try again. I normally go through posts in the mornings, and try to check a few times throughout the day, but I'm not here 24/7. There will typically be a significant delay before posts are approved. Just be patient.

  • New Core Animation tutorial

    Duncan C;420192 said:
    I started adding more descriptive info to the tutorial about the different techniques shown in the demo app. Check it out.
    I just added a UIView animation to the demo app using the
    animateWithDuration:delay:options:animations:completion:

    method.

    The new UIView animation supports tapping on the view as it moves to pause/restart the animation.

    It seems that gesture recognizers don't work on animations that are "in flight", even if you set the animation's UIViewAnimationOptionAllowUserInteraction flag.

    Recognizing taps on a view as its position changes due to Core Animation requires hit testing on the view's underlying presentationLayer. The same tap recognition code and animation pause/resume code works for both UIView animation and for CAAnimation object based animation.
