How to load images from Images.xcassets into a UIImage - xcode

Question

I am trying to code images to UIImage but I am having trouble. I am not sure how code it for each different image per list item. The app I am building is a List with pictures attached to each list item.
Below is the MyWhatsit class:
class MyWhatsit {
var name: String {
didSet {
postDidChangeNotification()
}
}
var location: String {
didSet {
postDidChangeNotification()
}
}
var image: UIImage? {
didSet {
postDidChangeNotification()
}
}
var viewImage: UIImage {
return image ?? UIImage(named: "camera")!
}
init( name: String, position: String = "" ) {
self.name = name
self.location = location
}
func postDidChangeNotification() {
let center = NSNotificationCenter.defaultCenter()
center.postNotificationName(WhatsitDidChangeNotification, object: self)
}
}
Below is the Table View:
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return things.count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
let thing = things[indexPath.row] as MyWhatsit
cell.textLabel?.text = thing.name
cell.detailTextLabel?.text = thing.location
cell.imageView?.image = thing.viewImage
return cell
}
override func tableView(tableView: UITableView, canEditRowAtIndexPath indexPath: NSIndexPath) -> Bool {
// Return false if you do not want the specified item to be editable.
return true
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == .Delete {
things.removeAtIndex(indexPath.row)
tableView.deleteRowsAtIndexPaths([indexPath], withRowAnimation: .Fade)
} else if editingStyle == .Insert {
// Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
}
}

Answer 1

I believe all you need to do is create an array of images like you are with the title and subtitle. When you add another picture, add the image name to the array and append the tableView.
What I see in your code is a name and position. It looks like you need to add "image" and set it to the name of the image. For example, MyWhatsit(name: "Bob Smith", position: "midfielder", image: "bobSmithImage")... and then you set the cell's image view equal to the image name.
Hope this gets you moving!

You need to create your own personal category. For example sorting your players based on positions they play. Using a class that stores your images into an array. For example:
let goalkeeper = [UIImage(named:"ivanlucic"), UIImage(named:"manuelneuer")]
let rightBack = [UIImage(named:"danialves"), UIImage(named:"sergioramos")]
After you have a list of images, inside your cellForRowAtIndexPath you can do a checking, and reference it to the array your created.

Didn't get how you are setting the code in the tableview but you can add image name with names like
Where image key contains the image name you have stored in the XCAssets
var things: [MyWhatsit] = [
MyWhatsit(name: "Ivan Lucic", position: "Goalkeeper","image":"ivan"),
MyWhatsit(name: "Manuel Neuer", position: "Goalkeeper","image":"manuel")...]
And you can init the image at the same time you init the name
init( name: String, position: String = "", imagename:string ) {
self.name = name
self.position = position
self.imgview = UIImage(named:imagename)
}
