由于SDWEbImage中未捕获的异常'NSInvalidArgumentException'而终止应用

Question

I am trying to load images in my Table-list cells and for this i am using SDWebImage with pod 'SDWebImage', '~>3.8' .

Since 4 days on words I am getting exception like below

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIImageView sd_setImageWithURL:placeholderImage:]: unrecognized selector sent to instance 0x79685270

Please can someone help me find what I'm doing wrong in my code

code:-

#import <SDWebImage/UIImageView+WebCache.h>
#import "UIImageView+Cached.h"

[cell.mainimage sd_setImageWithURL:[NSURL URLWithString:url]placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

Answer 1

Podfile

platform :ios, '7.0'.
pod 'SDWebImage', '~>3.8'

If you are using Swift, be sure to add use_frameworks! and set your target to iOS 8+:

platform :ios, '8.0' .
use_frameworks!

Answer 2

It seems that the extension cannot be found at runtime.

You need to make sure that your project is linked with the framework in the right way.

You can try the following:

1. run pod update SDWebImage in the terminal - if you are getting the error since you updated the version
2. change the way you use the framework, using @import SDWebImage;

Does this work?

Hope you find this useful

[cell.imageView sd_setImageWithURL:url
              placeholderImage:nil
                     completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
                            if (error) {
                              self.imageView.image = [UIImage imageNamed:@"yourPlaceholderImageName"];
                            } else {
                              self.imageView.image = image;
                            }
}];
