Question

我有这段代码，我在尝试创建一组用户时遇到了问题。

如果我使用＆＃34; var userArray：[Users] = FakeData ＆＃34;给我以下错误＆＃34;无法转换类型＆＃39; User_TableViewController - ＆gt;的值（） - ＆gt; [用户]＆＃39;指定类型＆＃39; [用户]＆＃39;＆＃34;

如果我使用＆＃34; var userArray：[Users] = FakeData（）＆＃34;给出了以下错误＆＃34;在调用＆＃34;

中缺少参数＃1的参数

如果我使用＆＃34; var userArray：[Users] = [FakeDate] ＆＃34;我收到以下错误＆＃34;使用未解析的标识符＆＃39; FakeDate＆＃39;＆＃34;

有什么问题？我用完了想法xD

class User_TableViewController: UITableViewController {

    var userArray:[Users] = FakeData()

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return userArray.count
    }


    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let Cell = tableView.dequeueReusableCellWithIdentifier("userCell") as! UserCell_TableViewCell
        Cell.userImage.image = userArray[indexPath.row].getImage()
        Cell.userDescription?.text = userArray[indexPath.row].getFirstName()

        return Cell
    }

    func FakeData() -> [Users]{

        let Person1 = Users(firstName: "Usuario 1", lastName: "Apellido 1", email: "mail1@hotmail.com", password: "1234567", age: "18", gender: "Male", image: UIImage(named: "Apple48x48")!)
        let Person2 = Users(firstName: "Usuario 2", lastName: "Apellido 2", email: "mail2@hotmail.com", password: "1234567", age: "18", gender: "Male", image: UIImage(named: "Apple48x48")!)
        let Person3 = Users(firstName: "Usuario 3", lastName: "Apellido 3", email: "mail3@hotmail.com", password: "1234567", age: "18", gender: "Male", image: UIImage(named: "Apple48x48")!)

        return [Person1, Person2, Person3]

    }

}

您应该在方法内初始化数组，例如$folder1 = "<external server>" $folder2 = "<local path>" # Get all files under $folder1, filter out directories $firstFolder = Get-JFSChildItem $folder1 | Where-Object { -not $_.PsIsContainer } $firstFolder | ForEach-Object { # Check if the file, from $folder1, exists with the same path under $folder2 If (!(Test-Path($_.FullName.Replace($folder1, $folder2)))) { $fileSuffix = $_.FullName.TrimStart($folder1) Write-Host "$fileSuffix is only in folder1" Receive-JFSItem $fileSuffix -destination $folder2 } }或viewDidLoad。对于属性声明，请设置

init

或

var userArray:[Users]!

然后在里面（例如）var userArray:[Users] = []：

viewDidLoad

（同样的惯例是命名以小写字母开头的方法，所以userArray = FakeData()，在你尝试编写FakeDate而不是FakeData的一次尝试中，变量名也应该以小写字母开头，即cell不是Cell
