[英]How to navigate from an embedded collection view’s cell to another view controller without using Storyboard or IB?
[英]How can I passed data from collection view cell to new view controller (programmatically and without storyboard)?
我有关于将数据从集合视图单元格传递到新视图控制器的问题。 我有集合视图单元,每个单元都有图像和标签,我想为每个单元创建新的视图控制器。
我已经尝试过UINavigationController,但是在didSelectItemAt indexPath函数下无法显示和navigationController代码。 每个人都使用情节提要进行此操作,但我没有使用它,也找不到解决方案。
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
print("#\(indexPath.item)!")
//let cell = collectionView.cellForItem(at: indexPath) as! itemsCell
//let cell = itemler[indexPath.row]
let newView = UINavigationController(rootViewController: orderBasketController())
self.present(newView, animated: true, completion: nil)
}
代码有一个错误,其错误类型为'feedCell'的Value没有成员'present' 。
尝试在init
方法中注入依赖项以查看控制器。
func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
guard let yourCell = collectionView.cellForItem(at: indexPath) as? YourCellClass else {
return
}
let yourModel = Model(title: yourCell.title, image: yourCell.image)
let targetViewController = TargetViewController(model: yourModel)
navigationController?.pushViewController(targetViewController, animated: true)
// or if it's not in navigation controller
// present(targetViewController, animated: true, completion: nil)
}
