如何更改动画UIImage的持续时间？

Question

I want to change my animated UIImage in UIImageView duration during runtime, but it's property is read-only and there are no methods like setDuration . Is it possible? In viewDidLoad i call this

-(void)prepareImage
{
    UIImage *image = [UIImage animatedImageNamed:@"image-" duration:1.0f];
    UIImageView *imageView = [[UIImageView alloc] initWithImage:squirrelImage];
    self.imageView=imageView; //property with UIImageView
}

Then on some event i do this

-(UIImageView *)redrawedImage
{
    UIImageView *newImageView = self.imageView;

    //a lot of translations and scales

    return newImageView;
}

and i want to put animation's duration change inside without resetting the whole animation.

Answer 1

UIImage * toImage = [UIImage imageNamed:@"myname.png"];
[UIView transitionWithView:self.imageView
                  duration:5.0f
                   options:UIViewAnimationOptionTransitionCrossDissolve
                animations:^{
                  self.imageView.image = toImage;
                } completion:nil];
