How to pass array of images to detailView Swift? - arrays

Question

Well I have been making a test app to continue my swift learning, today I came across a problem.
Basically I have a tableview and a detailview. For my tableview file I have some data that I am currently passing to the detailview, like the name that goes on the navigation bar, one image and some text, this data is stored in arrays on my tableview file, I use "prepareforsegue" to pass this information:
var names = ["name1","name2","name3"]
detailViewController.detailName = names[indexPath.row]
Then in my detailViewController I have variables set for that:
var detailName: String?
Then I use this for stuff, example: naming my navigation bar or setting an image in detailView:
navigationItem.title = detailName!
Now, what I dont get how to do is pass a whole array of information to a variable in my detailViewController. What I want to do is pass an array of images to use it on my detailView. I want to be able to iterate through the array of images with a button, I know how to set that up but I just need to know how to pass the array, right now I am just passing one of the values(one name, one image etc...)
Thanks for the help in advance.

Answer 1

It's not so different from what you have done.
Just add field for images in detailViewController, and then pass images using it. Images could be represented in [UIImage]. However, [String] can be also used for local filenames, and [NSURL] can be used for remote image urls.
code:
In DetailViewController:
var images: [UIImage]? // or var images: [UIImage] = []
In prepareForSegue:
detailViewController.images = YourImages

You seem to be asking for one of two things:
A UIImage array, which you can declare using var imageArray : [UIImage] = [] and then append whatever images you want to pass.
Alternatively, you can pass in a [AnyObject] array and cast its elements to a UIImage or String by doing
var objectArray : [AnyObject] = []
objectArray.append("test")
objectArray.append(UIImage(named: "test.png")!)
if let s = objectArray[0] as? String {
// Do something with the string
}
if let i = objectArray[1] as? UIImage {
// Do something with the image
}
if let s = objectArray[1] as? String {
// The above cast fails, this code block won't be executed
} else {
// ... but this one will
}

in the table view controller file:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
// Get reference to the destination view controller
var detailVC = segue.destinationViewController as! DetailViewController
var detailImages: Array<UIImage> = []
detailImages.append(UIImage(named: "pup.png")!)
detailImages.append(UIImage(named: "cutepuppy.png")!)
detailVC.detailImages = detailImages;
}
and in the detail file:
var detailImages: Array<UIImage>?
