objective-c - SDWebImage successfully loads the image, but cannot be displayed on the program?

Question

I use SDWebImage to load pictures, but occasionally one picture cannot be displayed.
I checked and found:

    1.下载成功后,能获取图片的尺寸等信息,
    2.更改SDWebImage 的options选项为options:SDWebImageRetryFailed
    3.用小面包检查,发现图片有显示,但是模拟器上则没有
    以下为对比图
    请各位朋友帮忙看看;

Answer 1

Is the picture added to the wrong imageView, or is the picture covered?
