Show activity indicator in SDWebImage

Question

I\'m using SDWebView image and i want to show an Activity Indicator as placeholder, while fetching the image from remote.

I tried Malek\'s answer here How to show an act

Answer 1

Best solution that worked for me is below. It is beautiful and encouraging to show progress indicator when image is downloading. I used UICircularSlider as rounded progress view. You can also try it.

    [_imgPost sd_setImageWithURL:urlPost placeholderImage:zeroImage options:SDWebImageContinueInBackground progress:^(NSInteger receivedSize, NSInteger expectedSize)
    {
        CGFloat domandeFloat = [[NSNumber numberWithInteger: receivedSize] floatValue];
        CGFloat corretteFloat = [[NSNumber numberWithInteger: expectedSize] floatValue];


        float currentProgress = (domandeFloat/corretteFloat)*100;

        NSLog(@"progress %.f%%",currentProgress);
        DBG(@"%li, %li", receivedSize, expectedSize);
        [_progress setValue:currentProgress];
    } completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {

        [_progress setHidden:YES];
    }];

Here _progress is an instance of UICircularSlider
