Changing timing for looping uiview animation
I have a heart rate looping scaling animation. Every 5 seconds I get new data. How can I adjust the looping scale rate without removing the animation before setting the new rate without hiccups?

Coordinating animation of layers with a UIView animation
I have a UIView which frame I am animating to a new location/size using [
UIView animateWithDuration:animations ]. The view's layer has a custom sublayer
which it's laying out either in layoutSubviews or layoutSublayersOfLayer:,
either seems to work. That sublayer is also moving to a new position depending
on the new UIView bounds. What I want is the two animations to go together,
using whatever the duration set in the UIView's animateWithDuration:animations:
call because that is the point at which I know how long the animation needs to
be.
The only way I've found to do this so far seems really hacky, to nest a
CATransaction within the UIView animation and give them the same time, is there
a better way to accomplish something like this?
NSTimeInterval interval = 2f;
[ UIView animateWithDuration:interval animations:^{
[ CATransaction begin ];
[ CATransaction setAnimationDuration:interval ];
self.faceView.frame=faceViewFrame;
[ CATransaction commit ];
} ];

Re: Coordinating animation of layers with a UIView animation
After setting up your UIView animation, you can introspect the animation timing
by looking at the respective view's layer.animations. Your can then apply that
animation to your sublayer.
For bonus points, just start using a subview instead of a sublayer :)

Re: UIView animation (backgroundColor) + drawRect:
As ever, thanks very much David. I figured there was *something* going on when
drawRect: was defined but I wouldn't have figured out what without this help.
In this case a crossfade in every case for that particular view works
perfectly, I implemented what you suggested and it looks so much better, it's
amazing the difference that even a .3-.5 second smooth transition can make,
just takes the edge off something which was quite harsh before, looks much more
professional.
Got the point (again) on using simple subviews when possible, a mistake I've
made before. In this particular case I don't think that was going to work, but
I'm very happy with what I have now.
Andreas, thanks for your reply too. You had pretty much exactly the same
thoughts I did and we both tried the same ideas, with the same
..AllowAnimatedContent etc and got the same results; hope David's reply was
useful to you too, it goes in my 'keepers' file.

When you implement -drawRect:, the background color of your view is then
drawn into the associated CALayer, rather than just being set on the CALayer
as a style property. Now Core Animation can animate both transitions, but
UIView disables the animation of a layer's contents, which thus prevents you
from getting a contents crossfade (as in the vast majority of cases this
wouldn't be what you want).
The crossfade may be exactly what you want in this case. Likely the best way
to defeat UIView's override in this case may be to create a subclass of
CALayer that overrides -actionForKey:. In that override, you would check for
the @contents key and return a CABasicAnimation ([CABasicAnimation
animation] should do it) and in all other cases return what the default
implementation does. This has the downside that you will *always* cross fade
and you won't be able to integrate with UIKit's animation APIs (you just get
animation for contents on all the time).
Another solution would be to use a super view that contains just the
background color and have your lines composited over it (assuming they are
simple lines this could be done with simple subviews that are sized for each
line). This would allow you to avoid -drawRect: entirely, which would allow
you to animate the background color and may offer some memory usage benefits
(if you can use subviews).

UIView animation (backgroundColor) + drawRect:
I was trying to animate the backgroundColor of one of my UIView subclasses
yesterday using
[ UIView animateWithDuration:2.0 animations:^{ [ myView
setBackgroundColor:someColor ]; } ];
but no matter what the duration set, the background color was changing
instantly. Whilst looking to see if there were two places I called
setBackgroundColor: (there weren't) I realized that my UIView subclass has its

drawn on it, so it needs a custom drawRect: method). Commenting that out, the
view background animated properly, but of course I had no content. Even just
adding an empty drawRect: method was enough to defeat the animation.
My assumption is that if there is no custom drawing, the view can smoothly
animate its layer between the two colors, and animate any other simple
properties, but if there is custom drawing, it doesn't want to call that
constantly as it animates the color change, so animation doesn't happen.
Is there anything I missed which will make this work,? I was thinking that the
other transition animation methods ( [ UIView transitionWithView: .. ] ) take a
'before' and 'after' snapshot and then, if you are flipping, animate one away,
and one in. I perhaps expected that UIView to do basically that, and crossfade
the old view out and the new one in, but I see no option for that, just flips
and curls, I want fade. This would be more generally useful than just this
example.
Obviously I have a few other options including building an entirely new UIView
on a color change, adding them both and fading their alphas in and out, or
splitting my 'paper' into a background view and an otherwise-clear lines view.
That may well be the right way to go with this, however I was interested to
know if there was some part of UIView animation which would automatically
handle a smooth transition of one single UIView between two drawn states.

Intuitively, a possibly solution would look like this:
UIView* view = self.helloView;
[UIView transitionWithView:view
duration:2.0
options:UIViewAnimationOptionAllowAnimatedContent |
UIViewAnimationOptionTransitionNone
animations:^{ view.backgroundColor = [UIColor greenColor];
}
completion:NULL];
Unfortunately, I couldn't get the background color to fade smoothly for UILabel
or IUView whose drawRect is overridden as well. Implicit layer animations
didn't work either.
For plain UIView instances the code above works with smooth animations, though.
The simplest version is:
[UIView animateWithDuration:2.0 animations:^{
self.helloView.backgroundColor = [UIColor greenColor];
}];
Obviously I have a few other options including building an entirely new
UIView on a color change, adding them both and fading their alphas in and
out, or splitting my 'paper' into a background view and an otherwise-clear
lines view. That may well be the right way to go with this, however I was

drawn states.
Well, there is - but transition means the process of creating another image
(from the original) and then move (in some animated way) from the original
position to the target position. Fading the background color might not be a
transition. However, when specifying the option
UIViewAnimationOptionAllowAnimatedContent in a transition I would hope property
changes would be simultaneously animated - and it did for UIViews.
A solution for your problem may look like this:
UIView* fromView = self.helloView;
UIView* toView = ... // copy the fromView
toView.alpha = 0.0;
toView.backgroundColor = [UIColor greenColor]; // change the background
color
[self.view insertSubview:toView aboveSubview:fromView];
[UIView animateWithDuration:2.0
animations:^{
fromView.alpha = 0.0;
toView.alpha = 1.0;
}
completion:^(BOOL finished){ [fromView
removeFromSuperview]; }];
self.helloView = toView;
[toView release], toView = nil;

missing features in iOS 4 block-based UIView animation
The iOS 4 syntax for using Objective-C blocks with UIView animation (instead of the old-style UIView animation block, love the confusing terminology here) is delightful, but some features are missing: * You can't designate a delegate, so you can't get a notification when the animation is about to start. * You can't specify a fixed number of repetitions. I have code that relies on this feature (e.g. a view that shakes its head by vibrating back and forth three times). What are folks doing to compensate?

I got this custom view on screen which I want to remove from the screen by moving it outside the left border of the screen. However at the same time, I want to move it back in from the right side but at a different y-Coordinate. So for instance it moves out at y=44 and at the same time it moves back in from the other side at y=0. I tried several approaches and the most promising (I reckon) is to create a copy of the view. This is not so easy though because UIView does not implement NSCopying. My custom view also has subviews and well the animation apparently gets a little confused if you animate two different (equal but different object) views which share the same subviews. Has anybody the slightest idea how I could achieve this? Every tip is welcome :)! Capture the view you want to animate into a UIImage. Add two image views with that image to the view hierarchy. One will be directly over your original view and the other will offscreen to the right. Hide your original view. Then, animate both image views as needed. When animation ends, unhide the original view, then remove both image views. Other notes... You may want to ensure that when your original view is hidden, its container view has say a black background (or whatever background you want during the animation). Note that by taking static images of your original view, no animations on that view itself will run during the overall animation. Probably a good thing though. ___ Ricky A.

[iPhone] customizing UIView animation run background color
Hi I am using following method to flip between UIViews that have imageviews on it as background. When I animate the views. I could see white background color at animating time. Can I change this color. What I currently do is like this. [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:1.25]; [UIView setAnimationCurve:UIAnimationCurveEaseInOut]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; [self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:2]; [UIView commitAnimations]; while at animation time white background color is there. Could I change this ? Thank you -Tharindu ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [iPhone] customizing UIView animation run background color
before animation I have set the background color but it did not work. Still it was white even I set it to black. it seems like color is not coming from self.view ?? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: [iPhone] customizing UIView animation run background color
This is the method I use to switch views. And my views are created with
Interface Builder
- (IBAction)switchViews {
self.view.backgroundColor = [UIColor blackColor];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:1.25];
[UIView setAnimationCurve:
UIAnimationCurveEaseInOut];
[UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft
forView:self.view cache:YES];
[self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:2];
[UIView commitAnimations];
}
I cannot guess why its white bacground when animation runs :( Could any one
guess why is it ?
Thank you.

May I point out the spelling of the second part of the selector? In
the method, it's fin_i_shed; in the argument, it's fin__shed.

Yeah, he knows.
This is the whole problem with passing things around as strings (selector
names, key-value coding, etc.); there are so many places to go wrong, and
when you do, it can be hard to debug. m.

UIView animation docs question
The documentation for setAnimationDidStopSelector in the XCode 3.2.1: says this: ...The message sent to the animation delegate after animations end. The default value is NULL. The selector should be of the form: - (void)animationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context. Your method must take the following arguments:... I created a method using this signature, but it was never called. I looked through some sample code from Apple and found at least one example that actually uses its own user defined selector that takes no arguments. Mimicking that, I created my own selector and that actually gets called. So my question is two fold: 1) Is this a bug in the documentation? 2) If I want the data that should be passed to the selector, how do I go about it?

Paste your code in which you set the delegate and the longer selector you
want; also the callback you wanted Core Animation to use (you can omit
the body of the method).

UIView animation
Hi,
I'm new to cocoa and have started to develop a board game for the
iPhone.
I've been looking at the ColorSlidingPuzzle example provided by Apple.
I managed to animate a piece move using the function:
- (void) movePiece:(Move*) move {
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.50];
// Change the position of my piece (an UIImageView)
[UIView commitAnimations];
}
Now here is my problem. I have an array with several moves that I want
to display.
Doing a for loop obviously doesn't work. Only the last move is
displayed (because nothing is updated until returning to the run loop
I guess)...
for(Move *move in moveArray)
[self movePiece:move];
How can I display this succession of moves?
Thanks
Benjamin
