SDWebImage链接问题

Question

I am trying to use SDWebImage framework for asynchronous loading and caching images. I could integrate SDWebImage project in to my project and build successfully. But I cannot use this line of code

[pCell.imgViewThumb sd_setImageWithURL:[NSURL URLWithString:aPromo.picture_url_thumb] placeholderImage:[UIImage imageNamed:@"Placeholder.png"]];

It gives this error

No visible @interface for 'UIImageView' declares the selector 'sd_setImageWithURL:placeholderImage:'

But the sd_setImageWithURL: method and the class already added in the project. I tried several times cleaning the project, re-linking the frameworks etc... But didn't work

Answer 1

You need to import the category. Type

#import <SDWebImage/UIImageView+WebCache.h>

on top of the file.

Answer 2

Do you need to import the SDWebImage category file? I believe it is called UIImageView+WebCache.h. The code would look like (at the top of your file with the other imports):

#import <SDWebImage/UIImageView+WebCache.h>

Answer 3

尝试导入导入“ SDWebImage / UIImageView + WebCache.h”

Answer 4
