Ignore my parallel issue with loading views - they are not affecting this.
I've now made a simple project which exhibits this animation issue.
I create a view based ipad app
Add a toolbar to the top
and add two buttons to the main view: "Animate" and "Nothing"
The button that comes with the toolbar pops up a popover
The popover contains a single button, "Animate", and some space.
Both "Animate" buttons are connected to a method of the main view controller
(see below).
When I touch the "Animate" in the main view, both the touched Animate button
and the Nothing button are animated.
When I touch the "Animate" in the popover, only the touched Animate button is
animated, not the Nothing button.
Question is: Why doesn't the Nothing button animate in all calls to the method?
- (IBAction) animateStuff: (id) sender
{
UIButton *b = (UIButton*)sender; // either one of the Animate buttons
[ UIView animateWithDuration: 0.25
delay: 0.01
options: UIViewAnimationOptionCurveEaseIn
animations: ^{
// move the "Animate" button
CGRect r = b.frame;
r.origin.x = r.origin.x + 10;
r.origin.y = r.origin.y + 5;
b.frame = r;
// resize the "Nothing" button
r = self.nothingButton.frame;
if( r.size.width == 400 )
{
r.size.width = 100;
r.size.height = 100;
}
else
{
r.size.width = 400;
r.size.height = 400;
}
self.nothingButton.frame = r;
}
completion: nil
];
}
