行上的连续声明必须用“;”分隔

Question

func createButtonWithTitle(title: String) -> UIButton {

  let button = UIButton.buttonWithType(.System) as UIButton
  button.frame = CGRectMake(0, 0, 20, 20)
  button.setTitle(title, forState: .Normal)
  button.sizeToFit()
  button.titleLabel.font = UIFont.systemFontOfSize(15)
  button.setTranslatesAutoresizingMaskIntoConstraints(false)
  button.backgroundColor = UIColor(white: 1.0, alpha: 1.0)
  button.setTitleColor(UIColor.darkGrayColor(), forState: .Normal)

  button.addTarget(self, action: "didTapButton:", forControlEvents: .TouchUpInside)

  return button
}

在UIButton 之前的第 1 行引发错误。 我该如何解决？

Answer 1

只需将 -> 替换为 ->，这就是它应该的样子。

附录：

您还没有显示您仍然遇到的后续错误；但是，我决定测试您的代码并设法在 Xcode 7.1（在 Swift 2 中）为您修复这些问题。

请查看 cmets 中所做的更改。

func createButtonWithTitle(title: String) -> UIButton 
{
    //buttonWithType is no longer available; please change it to
    //UIButton(type:)
    let button = UIButton(type: .System) as UIButton

    button.frame = CGRectMake(0, 0, 20, 20)
    button.setTitle(title, forState: .Normal)
    button.sizeToFit()

    //unwrap titleLabel using "!"
    button.titleLabel!.font = UIFont.systemFontOfSize(15)

    //translatesAutoresizingMaskIntoConstraints is a property and
    //it is no longer a member function
    button.translatesAutoresizingMaskIntoConstraints = false

    button.backgroundColor = UIColor(white: 1.0, alpha: 1.0)
    button.setTitleColor(UIColor.darkGrayColor(), forState: .Normal)

    button.addTarget(self, action: "didTapButton:", forControlEvents: .TouchUpInside)

    return button
}
