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
