SDWebImage into NSArray

Question

How can I add 3 imageviews using SDWebImage into NSArray?

I have my images in this form:

[self.imageView1 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"image1"]]
                    placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

[self.imageView2 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"image2"]]
                    placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

[self.imageView3 setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"image3"]]
                    placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

Your 2nd piece of codes contain invalid syntax. Double check. By the way, "does not work" is not an issue description — Raptor, Jun 18 '14 at 07:03

SDWebImage has another method with the completion block. Use that method

[self.imageView setImageWithURL:[NSURL URLWithString:[self.objc objectForKey:@"image1"]]
               placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                      completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {

                          //completion code here ...

                          [self.animationArray addObject:image]; // animationArray is an array property
                      }];

Add the image to the animationArray from the completion block

And if I want to add 3 different images with different URLs, I have to add the three time into block with this method? Isn`t there any other way? – Milan1111 Jun 18 '14 at 07:56
In SDWebImage no other way. otherwise you could use your own method – Anil Varghese Jun 18 '14 at 08:05

If adding the 3 imageViews to your array is what you are aiming at then your second piece of code should be

  NSArray *animationArray = [NSArray arrayWithObjects:self.imageView1, self.imageView2, self.imageView3, nil];

Although using the completion block is being suggested in the answer and maybe the best practice, this approach should also should manage fine considering that your imageWithURL call from SDWebImage will handle the network operation and update the objects when it receives the image.

This post is being automatically flagged as low quality because it is so short. Would you mind expanding it by adding some text to explain how it solves the problem? – gung - Reinstate Monica Jun 18 '14 at 13:02
I have added further detail, does the explanation suffice now? – Vijay Tholpadi Jun 19 '14 at 03:25
It does but it doesn`t work well. I did it like this and getting error. – Milan1111 Jul 04 '14 at 18:18
