【问题描述】:
我的堆栈视图中有两个表视图。我正在根据从 Firestore 检索到的数据量调整它们的大小。我面临的问题是,当表格视图调整顶部表格视图的大小时,“ingredientsTV”显示了所有数据,而“instructionsTV”只显示了一些数据。我的 array.count 显示了数组中正确数量的项目,但这些项目没有显示出来。
//Code for resize tableviews
override func viewWillLayoutSubviews() {
super.updateViewConstraints()
self.ingredientsTVHeight?.constant = self.ingredientsTV.contentSize.height
self.instructionsTVHeight.constant = self.instructionsTV.contentSize.height
self.ingredientsTV.contentInset = UIEdgeInsets(top: 0, left: -20, bottom: 0, right: 0)
self.instructionsTV.contentInset = UIEdgeInsets(top: 0, left: -20, bottom: 0, right: 0)
}
//setupview, called in viewdidload
//MARK: Functions
private func setupView() {
ingredientsTV.delegate = self
ingredientsTV.dataSource = self
instructionsTV.delegate = self
instructionsTV.dataSource = self
recipeImage.layer.cornerRadius = 5
recipeNameLbl.text = recipe.name
prepTimeLbl.text = recipe.prepTime
cookTimeLbl.text = recipe.cookTime
servesLabel.text = recipe.serves
if let url = URL(string: recipe.imageUrl) {
recipeImage.kf.setImage(with: url)
recipeImage.layer.cornerRadius = 5
}
}
//MARK: Tableview functions
extension PocketChefRecipeDetailsVC {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if (tableView == self.ingredientsTV) {
return recipe.ingredients.count
}else {
return recipe.method.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if (tableView == self.ingredientsTV) {
let cell = ingredientsTV.dequeueReusableCell(withIdentifier: "ingredientsCell", for: indexPath) as? ingredientsCell
cell?.ingredientsLbl.text = recipe.ingredients[indexPath.row]
return cell!
}else {
let cellB = instructionsTV.dequeueReusableCell(withIdentifier: "instructionsCell", for: indexPath) as? InstructionsCell
cellB?.instructionsLbl.text = recipe.method[indexPath.row]
return cellB!
}
}
}
*配方数据是从前一个视图控制器传递过来的
