快速错误: Consecutive declarations on a line must be separated by ';'

Question

这是我的代码:

import UIKit

class PlaylistMasterViewController: UIViewController {

@IBOutlet weak var abutton: UIButton!

override func viewDidLoad() {
    super.viewDidLoad()

    abutton.setTitle("Press me!", forState: .Normal)


}

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

override func prepareForSegue(segue: UIStoryboardSegue, sender:     AnyObject?) {
    if segue.identifier ==  "showPlaylistDetailSegue" {
        let playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController

        playlistDetailController.segueLabelText = "Yay!You Pressed"
}


}

我在最后一行遇到错误!我的 xCode 版本是 6.3.2 .. 我无法克服这个问题，因为应用程序总是失败。我在这里遇到两个错误:1- 一行中的连续声明必须用“;”分隔2- 预期声明

提前致谢

Answer 1

您缺少结束括号来结束您的类(class)，我通过在每次打开和关闭括号时添加注释来演示这一点，例如:

if myVar == 1 { //OPEN: 1
  //do something
} //CLOSE: 1

1 只是一种跟踪哪个括号是哪个的方法，所以如果你有多个括号(你确实这样做了)，你会看到类似的东西

//OPEN: 2 and //CLOSE: 2

我在下面添加了您的代码，显示您的括号何时打开和关闭。

import UIKit

class PlaylistMasterViewController: UIViewController { //OPEN: 1

  @IBOutlet weak var abutton: UIButton!

  override func viewDidLoad() { //OPEN: 2
    super.viewDidLoad()
    abutton.setTitle("Press me!", forState: .Normal)
  } //CLOSE: 2 -- 1 still needs to be closed

  override func didReceiveMemoryWarning() { //OPEN: 3
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
  } //CLOSE: 3 -- 1 still needs to be closed

  override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) { //OPEN: 4
    if segue.identifier ==  "showPlaylistDetailSegue" { //OPEN: 5
      let playlistDetailController = segue.destinationViewController as! PlaylistDetailViewController
      playlistDetailController.segueLabelText = "Yay!You Pressed"
    } //CLOSE: 5 -- 1 & 4 still need to be closed
  } //CLOSE: 4 -- 1 still needs to be closed

// This is where you need to close 1, you're missing the bracket under this comment

} //ADD ME -- CLOSE: 1 -- no brackets to close left

我希望您现在能更清楚一点。请正确练习缩进代码，这样可以节省大量调试此类简单错误的时间! :)
