How to show an activity indicator in SDWebImage

Question

Currently i am integrating SDWebImage in my project by following below things

1)#import \"UIButton+WebCache.h\"

2)[button setImageWithURL:url placeholderImag

Answer 1

Works like a charm for me :

Swift 3:

imgView.setShowActivityIndicator(true)
imgView.setIndicatorStyle(.gray)
imgView.sd_setImage(with: URL(string: urlString), placeholderImage: UIImage(named: "placeholder"))

Swift 4: (Edit : Updates)

imgView.sd_setShowActivityIndicatorView(true)
imgView.sd_setIndicatorStyle(.gray)
imgView.sd_setImage(with: URL(string: urlString), placeholderImage: UIImage(named: "placeholder"))

Swift 5: SDWebImage (5.x.x)

imgView.sd_imageIndicator = SDWebImageActivityIndicator.gray
imgView.sd_setImage(with: URL(string: urlString), placeholderImage: UIImage(named: "placeholder"))

Updates: For UIButton use this

yourButton.sd_setImage(with: URL(string: urlString), for: .normal)
