回答by Epic Defeater
Instead of i * self.view.frame.size.width, use CGFloat(i) * self.view.frame.size.width
而不是i * self.view.frame.size.width，使用CGFloat(i) * self.view.frame.size.width
回答by Chetan
You need to type cast i into CGFloat, write your line of code as
您需要在CGFloat 中输入 cast i，将您的代码行写为
var frame: CGRect = CGRectMake(CGFloat(i) * self.view.fram.size.width, self.tutorialHolderView.frame.origin.y, 0, self.tutorialHolderView.frame.size.height)
var frame: CGRect = CGRectMake(CGFloat(i) * self.view.fram.size.width, self.tutorialHolderView.frame.origin.y, 0, self.tutorialHolderView.frame.size.height)
