Swift 4.2随机化 [英] Swift 4.2 randomizing

问题描述

我是Swift的新手并且正在努力学习。



如何从1到100的范围内选择5个随机数而不重复之前被选中了吗？



我尝试了什么：



Don'知道从哪里开始。我一直在努力学习使用Udemy课程和youtube视频

解决方案

这是我的解决方案：

 import UIKit 
 
 var repeatCounter = 1 
 var pickedNumbers = [Int]（）
 
 repeat {
 
 let rangeValue = Int.random（in：1 ... 100）
 
 if pickedNumbers.contains（rangeValue）{
 
 print（\（rangeValue）已存在于数组中）
 
} else {
 
 pickedNumbers.append（rangeValue）
 print（[ pickNumbers]）
 repeatCounter + = 1 
} 
 
}而repeatCounter< 6 

I am very new to Swift and trying to learn.

How do I pick 5 random number from a range of 1 to 100 and not repeat a number that was previously picked?

What I have tried:

Don't know where to start. I have been trying to learn using a Udemy course and youtube videos

解决方案

Here's my solution:

import UIKit

var repeatCounter = 1
var pickedNumbers = [Int]()

repeat {
    
    let rangeValue = Int.random(in: 1...100)
    
    if pickedNumbers.contains(rangeValue) {
        
        print("\(rangeValue) already exists in the array")
    
    } else {

        pickedNumbers.append(rangeValue)
        print([pickedNumbers])
        repeatCounter += 1
    }

} while repeatCounter < 6
