仅当

objString.removeFirst()

 时才必须使用 

objString.first == "*"

同样

objGetString.removeLast()

当

objString.last == "*"

只要满足这些条件，你就可以开始了......

if (objString.first == "*" || objString.last == "*") && objString.count > 2 {
    if (objString.first == "*") {
        objString.removeFirst()
    }

    if (objString.last == "*") {
        objString.removeLast()
    }
    objString.append(" ")
