appending array with url iOS objective c - ios

Question

I have a base url and I have the image names in a array extracted from there server .I am using a collection view, I have to display all the 23 images in the collection view I have two problems
when I try to access cell.imageview.image it says no property image view in cell but in custom cell.h file I have created the outlet and I am using storyboard
2.as one is string base url and other end path or filename of the images in array extracted from john from server
this is how I get from data--
{
"added_by" = 1;
"category_id" = 182;
"category_image" = "shots.png";
"category_name" = Shots;
sequance = 19;
status = 0;
"store_id" = 1;
},
{
"added_by" = 1;
"category_id" = 168;
"category_image" = "classiccocktail.png";
"category_name" = "Classic Cocktails";
sequance = 20;
status = 0;
"store_id" = 1;
},
{
"added_by" = 1;
"category_id" = 167;
"category_image" = "sprit.png";
"category_name" = "Non Alcoholic Bevereges";
sequance = 21;
status = 0;
"store_id" = 1;
},
{
"added_by" = 1;
"category_id" = 162;
"category_image" = "nonalcoholic.png";
"category_name" = "Non Alcoholic Coolers";
sequance = 22;
status = 0;
"store_id" = 1;
}
this is nslog of server reply
This is the slog of the array in which I have stored the data

and I have a base url how to get all these images in collection view?

Answer 1

Register your custom cell in viewDidLoad method
[yourCollectionView registerNib:[UINib nibWithNibName:#"CustomCell" bundle:nil] forCellWithReuseIdentifier:#"your Cell Identifier"];
And then you will write on cellForItemAtIndexPath method
-(UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"your Cell Identifier";
CustomCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
NSDictionary *dict = imageAry[indexPath.row];
//SdWebimage to load image
[cell.imgUser sd_setImageWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"%#/%#", baseUrl, dict[#"imageName"]]];
return cell;
}
Download SDWebimageImageLoader to use of async image downloader with cache support.

Answer 2

NSString *path = [NSString stringWithFormat:#"%#/%#", baseUrl, imageName];
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *imgage = [[UIImage alloc] initWithData:data];
pass this image to your imageview.
As you are loading images from server, you can also use SDWebImage for image caching purpose.
