Struct check type | Swift - ios

Question

Have the structure where contains 2 types - image and text. Have an array, where it will be added. How to make type check in cellForRowAtIndexPath?
struct typeArray {
var text: String?
var image: UIImage?
init(text: String){
self.text = text
}
init(image: UIImage){
self.image = image
}
}
var content = [AnyObject]()
Image add button:
let obj = typeArray(image: image)
content.append(obj.image!)
self.articleTableView.reloadData()
Text add button:
let obj = typeArray(text: self.articleTextView.text as String!)
self.content.append(obj.text!)
self.articleTableView.reloadData()
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
if content[indexPath.row] == {
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Text Cell", forIndexPath: indexPath) as! TextTableViewCell
cell.textArticle.text = content[indexPath.row] as? String
return cell
}
else if content[indexPath.row] == {
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Image Cell", forIndexPath: indexPath) as! ImageTableViewCell
cell.backgroundColor = UIColor.clearColor()
cell.imageArticle.image = content[indexPath.row] as? UIImage
return cell
}
return UITableViewCell()
}

Answer 1

You should declare your content array to hold instances of your typeArray struct;
var content = [typeArray]()
Then add instances of the struct to the array:
let obj = typeArray(image: image)
content.append(obj)
self.articleTableView.reloadData()
Then you can use this in your cellForRowAtIndexPath -
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let rowStruct = content[indexPath.row] {
if let text = rowStruct.text {
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Text Cell", forIndexPath: indexPath) as! TextTableViewCell
cell.textArticle.text = text
return cell
} else if let image = rowStruct.image {
let cell = self.articleTableView.dequeueReusableCellWithIdentifier("Image Cell", forIndexPath: indexPath) as! ImageTableViewCell
cell.backgroundColor = UIColor.clearColor()
cell.imageArticle.image = image
return cell
}
return UITableViewCell()
}
