As you can see I am making a call to instagram's API for their 20 most recent pictures for two separate users "tuulavintage" and "wendyslookbook". I then parse the data for the imageUrls, put them into two separate for in loops where I take those imageUrls and change them to UIImages and put them inside the "let photos = NSMutableArray()". Then I add the UIimages to my collection view cell "cell.imageView.image = photos.objectAtIndex(indexPath.row) as? UIImage"
I also count my parsed NSdictionary response like so "self.photoCount = tuulavintageImageResponse.count + wendyslookbookImageResponse.count as Int". So I can tell my collection view how many cells to make
You can also see here (inside the global main que) "var tuulavintageTimeResponse = tuulavintageDictionary.valueForKeyPath("data.created_time") as NSArray"
and here
"var wendyslookbookTimeResponse = wendyslookbookDictionary.valueForKeyPath("data.created_time") as NSArray"
I parse my NSDictionary response to retrieve an array of unixtimecode for each image but they aren't connected.
My question is how to I order these photos being displayed in my collection view by the time they were posted using the unixtimecode I can retrieve? I have a feeling I need to match up the UIimage's with their specific timecode, then somehow tell my collection view to order them by unixtime.
Thanks in advance.
