SDWebImage-ProgressView

Category on UIImageView, adding a progress view while images are downloaded using SDWebImage (3.7.0 and up).
Example on Youtube

Installation

Use Cocoapods:

pod 'SDWebImage-ProgressView'

Usage

All of SDWebImage's UIView+WebCache methods gained an extra parameter:

- (void)sd_setImageWithURL:(NSURL *)url usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url completed:(SDWebImageCompletedBlock)completedBlock usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletedBlock)completedBlock usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletedBlock)completedBlock usingProgressView:(UIProgressView *)progressView;
- (void)sd_setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletedBlock)completedBlock usingProgressView:(UIProgressView *)progressView;

Use nil for the progressView parameter to use the system default UIProgressView, or provide your own progress view (or subclass thereof) if you want custom styling and tint colors.

If you're using the sd_cancelCurrentImageLoad method, you'll also have to call removeProgressView or you'll end up with lingering progress views.

- (void)prepareForReuse {
    [super prepareForReuse];
    [self.imageView sd_cancelCurrentImageLoad];
    [self.imageView removeProgressView];
}
