Yikes, so I did, and I had forgotten. Must be Codeheimer's disease.
That is the right answer. The routine is now,
- (void)fadeView:(UIView *)theView {
theView.alpha = 1.0;
infoButton.hidden = FALSE;
[UIView animateWithDuration:2.5
delay:0
options:UIViewAnimationOptionAllowUserInteraction
animations:^{theView.alpha = 0.0;}
completion:^(BOOL finished){infoButton.hidden = TRUE;}
];
}
and it does what I want.
Side question -- animateWithDuration:::::
is a class method. How does it know which view to act on?
