The easiest way to add a UIActivityView to your SDWebImage view

Installation

If you’re using CocoaPods (You are not?! You should!!) just add

pod 'UIActivityIndicator-for-SDWebImage'

into your Podfile file.

Alternatively, copy the class (.h and .m) into your application.

Usage

You can use all the standard SDWebImage methods… adding the last parameter

usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle 

So all the methods available are:

- (void)setImageWithURL:(NSURL *)url usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url completed:(SDWebImageCompletionBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletionBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletionBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletionBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;

Remove the activity indicator

Sometimes it’s useful to remove the activity indicator (for example when you call cancelCurrentImageLoad on the UIImageView). From now on the method removeActivityIndicator is public: fell free to use it!

Why?

Well, apparently SDWebImage team doesn’t want a UIActivityIndicatorView… (actually I found a bug in that commit, but I don’t think this is why they closed the issue)

Why? I don’t know.

And why a category instead of a fork? Well, I really don’t want to keep this repo updated with the (future) new SDWebImage commits (obvious, right?).

Ok, but we could modify our SDWebImage repo with these differences Yes… unless you’re using Cocoapods! If you’re doing it you should know that you can’t modify a repo, because at the next update, Cocoapods will delete all your work (pulling the new version and removing all your changes). So with a category you can keep your SDWebImage pod updated without problems :)
