[imagev sd_setImageWithURL:[NSURL URLWithString:#"http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/upload/post/"]
placeholderImage:[UIImage imageNamed:string2]

Answer 1

Aayush Katiyar,
From iOS 8 onwards you are not supposed to use http you should make use of secure channels https. In case you dont have one consider adding these to your plist
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
All your image download api is making use of http:// I guess that might be the issue here
Finally change the way you load the image as
[imagev sd_setImageWithURL:[NSURL URLWithString: [NSString stringWithFormat:#"%#/%#",#"http://dev-demo.info.bh-in-15.webhostbox.net/dv/nationalblack/upload/post/", string2]]
placeholderImage:[UIImage imageNamed:#"Some_Placeholder_Image"]
completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {
imagev.image = image;
}];

Answer 2

Just use like this,
[cell.myImageView sd_setImageWithURL:finalImageUrl];
finalImageUrl is your final url for download image.
No need to use method with completion handlerl. it is for different task.
