When i run my app this exception occurs in number of item in section on return
here is my code :
import UIKit
import Alamofire import SwiftyJSON
class DetailPage: UIViewController,UICollectionViewDataSource,UICollectionViewDelegate {
@IBOutlet weak var MyOtherProductsOfStoreCollectionView: UICollectionView!
@IBOutlet weak var MySameProductsCollectionView: UICollectionView!
@IBOutlet weak var img1: UIImageView!
@IBOutlet weak var profilePic: UIImageView!
@IBOutlet weak var username: UILabel!
@IBOutlet weak var productsCount: UILabel!
@IBOutlet weak var price: UILabel!
@IBOutlet weak var desc: UILabel!
var sameData:[SameAndOtherData]?
var otherData:[SameAndOtherData]?
var alldata: [PopulerUrunlerData]?
var indexPath: IndexPath?
override func viewDidLoad() {
super.viewDidLoad()
if let indexPath = self.indexPath, let popularUrunlerData = self.alldata?[indexPath.row] {
img1.downloadImage(from: popularUrunlerData.imgUrl!)
profilePic.downloadImage(from: popularUrunlerData.userpic!)
username.text = popularUrunlerData.username
productsCount.text = String( format:"%d", popularUrunlerData.productsCount!)
price.text = String(format: "%.1f", popularUrunlerData.price!)
desc.text = popularUrunlerData.desc
let id = popularUrunlerData.instagramId
let name = popularUrunlerData.username
sameProducts(from: "https://api.shopsta.com/product/\(id!)/similar")
otherProductsOfStore(from: "https://api.shopsta.com/product/\(name!)/\(id!)/others")
}
MyOtherProductsOfStoreCollectionView.delegate = self;
MySameProductsCollectionView.delegate = self;
MyOtherProductsOfStoreCollectionView.dataSource = self;
MySameProductsCollectionView.dataSource = self;
}
and my collectionView funds :
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
if (collectionView == self.MySameProductsCollectionView){
return (self.sameData?.count)!
}
else {
return (self.otherData?.count)!
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
if collectionView == self.MySameProductsCollectionView {
let cella = collectionView.dequeueReusableCell(withReuseIdentifier: "sameProducts", for:
indexPath as IndexPath) as! SameProductsCollectionViewCell
cella.img.downloadImage(from: (sameData?[indexPath.row].image)!)
return cella
}
else {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "otherProducts", for: indexPath as IndexPath) as! OtherProductsOfStoreCollectionViewCell
cell.img.downloadImage(from: (otherData?[indexPath.row].image!)!)
return cell
}
}
}
