如何在SDWebImage中显示活动指示器 [英] How to show an activity indicator in SDWebImage

问题描述

目前我正在通过以下方式将SDWebImage集成到我的项目中

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

1）#importUIButton + WebCache.h

1)#import "UIButton+WebCache.h"

2）[button setImageWithURL：url placeholderImage：[UIImage imageNamed：@no_photo.png]];

2)[button setImageWithURL:url placeholderImage:[UIImage imageNamed:@"no_photo.png"]];

所以它会显示清单图像存在于相应按钮上方的URL中。

So it will show the list of image present in URL above the respective buttons.

但是现在我想在下载图像时在按钮上方显示一个活动指示器，那么我该怎么做呢？ / p>

But Now i want to show an activity indicator above button when the image is getting downloaded ,So how can i do this?

Works like a charm for me :

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

Swift 4： （编辑：更新）

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