How do I make a semi-transparent view layer above a current view?

Question

You\'ve likely seen this before, its become exceedingly popular in consumery chic apps like ScoutMob. I\'m trying to implement a 60% transparent view on launch that will cover m

Answer 1

Just make a mechanism that figures out if it is the first launch of the app, then tells your main view controller to add a (probably image) view on top of the current view with 0.6 alpha

if (figureOutIfIsFirstLaunch)
{
    UIImageView *myOverlay = [...];
    myOverlay.frame = self.view.bounds;
    myOverlay.alpha = 0.6;
    [self.view addSubview:myOverlay];
}
