Question

例如，如果用户连续输入4和4，我希望看到值相同且输入的值为4 如果用户连续输入4和5，我希望看到值不同，输入的值是4,5。在我的代码userValue中，用户将输入并继续更改

var userValue:Int!
var outputValue:Int! = userValue

if (outputValue == userValue)
{
  print("Value is same and value entered is " + String(userValue))
}
else
{
    print("Values are different and values entered are ")
}

如何逐个显示用户每次输入的值，并根据上述内容做出决策？

Answer 1

let fullName : String = "A,B"
let fullNameArr : [String] = fullName.components(separatedBy: ",")

var firstName : String = fullNameArr[0]
var lastName : String = fullNameArr[1]

if (firstName == lastName)
{
 print("Value is same and value entered is " + String(userValue))
}
else
{
   print("Values are different and values entered are ")
}

尝试这可能会有所帮助。我没有检查
