在swift中乘以整数 [英] Multiplying ints in swift

问题描述

我是swift和iOS编程的新手，在这里慢慢学习。所以我有：

I am new to swift and iOS programming and learning slowly here. So I have:

@IBOutlet weak var timeEntered: UITextField!



@IBAction func countDown(sender: AnyObject)
    {
        var total = timeEntered.text.toInt()

        total = total *7


    }

line total = total * 7 给我错误一行上的连续语句必须以a分隔;

The line total = total *7 gives me the error "Consecutive statements on a line must be separated by a ;"

我在这里了解到你应该做（我不知道为什么但是......）

I read here that you should do ( I don't know why but...)

total = total! *7

我仍然得到同样的错误。任何帮助将受到高度赞赏。谢谢！

And still I get the same error. Any help would be highly appreciated. Thanks!

推荐答案

我认为你必须将'*'和'7'分开。试试这个总计=总计* 7

I think that you must separate the '*' and the '7'. Try this total = total * 7
