continuous animation within UITableViewCell

I'm trying to add a continuous animation onto my UITableViewCell-Subclass. It's a rather easy one with an Image fading in and out (fading between 0.4 alpha and 1.0), what I've tried so far ist the following:

-(void)animateRecordingIndicator{

    [UIView beginAnimations:@"RecordingIndicatorAnimation" context:nil];
    [UIView setAnimationDuration:0.3];

    [UIView setAnimationDelegate:self]; 
    [UIView setAnimationDidStopSelector:@selector(animationFinished)];

    if (animatedImageView.alpha == 0.4) 
        animatedImageView.alpha = 1.0;
    else 
        animatedImageView.alpha = 0.4;    

    [UIView commitAnimations];
}

the code within animationFinished is as follows:

-(void)animationFinished{
    if (doShowAnimation) {
        [self performSelectorOnMainThread:@selector(animateRecordingIndicator) withObject:nil waitUntilDone:YES];
    }
}

what I expect should be clear by now, but what I get is simply a crash with Xcode loading Stackframes more or less eternally :)

According to the UIView class reference, you are now discouraged from using the commitAnimations method. Instead use the following:

animateWithDuration:delay:options:animations:completion:

I imagine the infinite recursion you are encountering is related to Apple's reasons for making that recommendation.
