iOS开发 - 「Swift 学习」阶段首秀99乘法口诀表

根据近几天的Swift语言学习，秀一下利用Swift语言输出99乘法口诀表

首秀上才艺

//输出乘法口诀表
    func multiplicationSheet () {
        print("-------------------------9*9乘法口诀表-------------------------")
        for i in 1...9 {
            var resultStr:String = ""
            for j in 1...i {
                if(j == i){//该换行了
                    resultStr += "\(j) * \(i) = \(j * i)\n"
                }else {
                    resultStr += "\(j) * \(i) = \(j * i)  "
                }
            }
            print(resultStr)
        }
    }

输出结果
