it become looks like this
i've tried every objects and insert to uicollectionview, but it doesn't appear at all..is there any way to help?
here is my code
import UIKit
let reuseIdentifier = "Cell"
class SummaryViewController: UICollectionViewController, UICollectionViewDataSource, UICollectionViewDelegate {
#IBOutlet var collectionview: UICollectionView!
var photos:NSArray?
var items = NSMutableArray()
var TableData:Array< String > = Array < String >()
var json:String = ""
var arrayOfMenu: [ImageList] = [ImageList]()
override func viewDidLoad() {
super.viewDidLoad()
self.setUpMenu()
collectionview.dataSource = self
collectionview.delegate = self
NSLog("%d", items.count)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
override func numberOfSectionsInCollectionView(collectionView: UICollectionView) -> Int {
return 1
}
override func collectionView(collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return arrayOfMenu.count //hitung banyak data pada array
}
override func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCellWithReuseIdentifier(reuseIdentifier, forIndexPath: indexPath) as! UICollectionViewCell
let image = UIImage(named: items.objectAtIndex(indexPath.row) as! String)
let imageView = cell.viewWithTag(100) as! UIImageView
imageView.image = image
return cell
}
func setUpMenu() //membaca json pada setiap arraynya
{
var json: JSON = JSON (data: NSData())
DataManager.getactivityDataFromFileWithSuccess{ (data) -> Void in
json = JSON(data: data)
let results = json["results"]
for (index: String, subJson: JSON) in results {
}
for (var i = 0; i < json["Activity"].count; i++) {
if let icon: AnyObject = json["Activity"][i]["icon"].string {
self.items.addObject(icon)
dispatch_async(dispatch_get_main_queue(), {self.collectionView!.reloadData()})
var menu = ImageList(image: icon as! String)
self.arrayOfMenu.append(menu)
self.TableData.append(icon as! String)
}
}
}
}
override func collectionView(collectionView: UICollectionView, viewForSupplementaryElementOfKind kind: String, atIndexPath indexPath: NSIndexPath) -> UICollectionReusableView
{
let header = collectionView.dequeueReusableSupplementaryViewOfKind(UICollectionElementKindSectionHeader, withReuseIdentifier: "headersection", forIndexPath: indexPath) as! UICollectionReusableView
return header
}
}
