Swift UITableView 未显示所有结果

Question

我将 UITableView 连接到一个数组。 var shoppingList: [String] = ["鸡蛋","牛奶","A","B","C","D","E","F","G","H","I ","J","K","L","M","N","O"] 但是，当我在模拟器中运行应用程序时，它不允许我滚动到最后。这是为什么？我只能滚动到字母“I”并看到一半的“J”，但我无法进一步向下滚动。在 func tableView 中，它显示了正确的数组大小，所以我知道项目都在那里，但不能滚动到最后。下面是屏幕截图。谢谢你。 screen shot screen shot 2

这是代码

import UIKit

class TestTableViewController: UITableViewController {
    var shoppingList: [String] = ["Eggs", "Milk","A","B","C","D","E","F","G","H","I","J","K","L","M","N","O"]

    override func viewDidLoad() {
        super.viewDidLoad()

        print("test")
        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Incomplete implementation, return the number of sections
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete implementation, return the number of rows
        print(shoppingList.count)
        return shoppingList.count
    }

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("TestCell", forIndexPath: indexPath)

        // Configure the cell...
        cell.textLabel!.text = shoppingList[indexPath.row]
        // Configure the cell...
        print("here")
        return cell
    }

Julia，表格视图似乎比屏幕本身长。如果您进入故事板并缩短 tableview 的长度，您将能够看到其余部分，只要它与屏幕尺寸相同或更短。

您可以添加约束，这些约束将自动捕捉到适合任何大小的屏幕。

如果你想通过代码来做，在你的 viewDidLoad() 中试试这个

    tableView.frame.size = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)
