Hello o created UICollectionView without storyboard and i used RxSwift for data binding.
I showing images on cells but they're not showing before scroll.
func first(_ image : String) {
self.addSubview(firstView)
firstView.snp.makeConstraints { (make) in
make.right.equalToSuperview()
make.left.equalToSuperview()
make.top.equalToSuperview()
make.height.equalTo(3 * self.bounds.height / 4)
}
firstView.layer.masksToBounds = true
imageView.image = UIImage(named: "kitaplar")
imageView.frame = CGRect(x: 0, y: 0, width: firstView.frame.width, height: firstView.frame.height)
firstView.addSubview(imageView)
}
And my viewcontroller code is
self.kategoriArray
.throttle(1, scheduler: MainScheduler.instance)
.debug("arraItem", trimOutput: false)
.bind(to: kategoriColl.rx.items(cellIdentifier: "kategoriCell", cellType: KategoriCollectionViewCell.self)){(index,model,cell) in
cell.first("https://www.gravatar.com/avatar/d2bba3700fd3a3e8cc12888edd980525?s=23&d=identicon&r=PG")
cell.second(model.title as! String)
}.disposed(by: disposeBag)
I guess the problem is here
imageView.frame = CGRect(x: 0, y: 0, width: firstView.frame.width, height: firstView.frame.height)
as the frame of firstView may not yet correctly known , so encourage you to add constraints to the imageView
also if the imageView has same frame as it's parent ( firstView ) so you may get rid of that firstView and directly add the imageview to
self.contentView.addSubview(imageView)
Also i see no loading for the remote image so consider using SDWebImage
imageView.sd_setImage(with: URL(string:image), placeholderImage: UIImage(named: "kitaplar"))
