self.tableView.reloadData()在Swift中不起作用

我正在尝试同时学习开发Swift的基础知识iOS,所以请耐心等待.我有一个TableViewController首先解析本地JSON文件并将其非常简单的数据渲染到TableViewCellSectionHeaderViews中.在同一个中TableViewController,我正在调用一个JSON端点,它返回数据,然后我将其设置为变量,这样我就可以访问我实际想要获得的内容(API结构不太理想).所以,我最终设置了正确的数据self.tableData然后调用self.tableView.reloadData()但没有任何反应.是什么赋予了?

import UIKit

class BusinessTableViewController: UITableViewController {

    var data: NSMutableData = NSMutableData()
    var tableData: NSArray = NSArray()

    @lazy var Business: NSArray = {
        let pathTCT = NSBundle.mainBundle().pathForResource("TCT", ofType: "json")
        let data = NSData.dataWithContentsOfFile(pathTCT, options: nil, error: nil)
        return NSJSONSerialization.JSONObjectWithData(data, options: nil, error: nil) as NSArray
        }()

    override func viewDidLoad() {
        super.viewDidLoad()

        navigationItem.titleView = UIImageView(image: UIImage(named: "growler"))

        tableView.registerClass(BeerTableViewCell.self, forCellReuseIdentifier: "cell")
        tableView.separatorStyle = .None …

React-Native Packager失败:重复的模块名称

这在开发过程中似乎是随机发生的.当试图运行npm start或者react-native run-ios,我得到以下错误:

Failed to build DependencyGraph: @providesModule naming collision:
  Duplicate module name: react-native-vector-icons
  Paths: /Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/local-cli/rnpm/core/test/fixtures/files/package.json collides with /Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/Libraries/Animated/release/package.json

This error is caused by a @providesModule declaration with the same name accross two different files.

奇怪的是,/Users/chandlervdw/Repos/Relay/mobile/node_modules/react-native/local-cli/rnpm/core/test/fixtures/files/package.json实际上列表react-native-vector-icons作为模块的名称???

如果我删除该文件,则错误不再发生,但打包器卡在93%并且抱怨找不到完全无关的库.

我吹走了我的仓库,甚至重新安装了所有东西,包括 …

在Chrome上,输入type =“ number”的输入跳了2(Mac OS Catalina 10.15)

从字面上看

<input type="number" value="0" step="1" />

在我点击向上和向下时(对于箭头键而言),它跳了两下。

我的同事正在运行与我相同的Chrome版本(77.0.3865.90),它为他们跳了一个。唯一的区别是我正在运行Mac Catalina。Safari和Firefox都可以。这怎么可能?
