UIImageView does not fade in, but out

Question

I created an imageView with which I would like to display an error. I use animations to fade the image in / out. This is the code I use for the animation:

    imageView.hidden = NO;
    imageView.alpha = 0;

    [UIView animateWithDuration:.25 animations:^{
        imageView.alpha = 1;
    } completion:^(BOOL finished) {
        imageView.hidden = NO;
    }];


    imageView.alpha = 1;

    [UIView animateWithDuration:.25 delay:4.5 options:0 animations:^{
        imageView.alpha = 0;
    } completion:^(BOOL finished) {
        imageView.hidden = YES;
    }];

So my image does fade out as it should but it does not fade in, why ever. Do you have an idea?

Answer 1

Try this. I normally put the additional animations within the completion block of the first animation. I tested this and it works for me. If this doesn't work, check to make sure your imageView property is connected properly in your layout file.

imageView.hidden = NO;
imageView.alpha = 0.0f;

[UIView animateWithDuration:0.25f animations:^{
    imageView.alpha = 1.0f;
} completion:^(BOOL finished) {
    [UIView animateWithDuration:0.25f delay:4.5f options:0 animations:^{
        imageView.alpha = 0.0f;
    } completion:^(BOOL finished) {
        imageView.hidden = YES;
    }];
}];
