本人刚刚开始学习ios开发，老师要求实现一个刷牙APP的UI界面，遇上了几个问题，卡了两天了。。
我制作了一个UI界面 如图
主要遇上两个问题：
①我希望首次加载粉色女孩界面时，星星上的数字能显示daysStar数组里的Int数字。但在viewDidLoad()中写的button.titleLabel?.text=String(daysStar[1])语句并不能实现这个功能，请问原因是什么呢？(daysStar已经初始化为1，但真机运行时所有数字都初始显示0)
②我在storyboard中给三行按钮的titlelabel都写了一个0，每次点击右上角的刷牙按钮时，星星按钮的label数字会递增，但点击一下星星按钮，数字就会显示0。我尝试过不写0，但是不写0的话，点击按钮不会出现数字，也尝试过把星星用View叠加到粉色矩形上，但按钮的可用性会差很多。这个问题怎么解决呢?（星星按钮是使用了粉色为底的五角星图片）
代码有什么写的不好的地方，也欢迎大家指出呀！
MM界面代码如下：
import UIKit
class mmViewController: UIViewController {
var firstWeekday:Int?;
var daysStar = [Int](repeating: 1, count: 21)
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
// Initialize weekday labels
// print(daysStar)
// var daysStar = [Int](repeating: 1, count: 21)
// Load the weekdays' label
switch firstWeekday {
case 1:
firstLabel.text="周一"
secondLabel.text="周二"
thirdLabel.text="周三"
fourthLabel.text="周四"
fifthLabel.text="周五"
sixthLabel.text="周六"
seventhLabel.text="周日"
case 2:
firstLabel.text="周二"
secondLabel.text="周三"
thirdLabel.text="周四"
fourthLabel.text="周五"

thirdLabel.text="周日"

firstLabel.text="周六"
secondLabel.text="周日"
thirdLabel.text="周一"
fourthLabel.text="周二"
fifthLabel.text="周三"

case 7:
firstLabel.text="周日"
secondLabel.text="周一"
thirdLabel.text="周二"
fourthLabel.text="周三"
fifthLabel.text="周四"
sixthLabel.text="周五"
seventhLabel.text="周六"
default :
firstLabel.text="周一"
secondLabel.text="周二"
thirdLabel.text="周三"
fourthLabel.text="周四"
fifthLabel.text="周五"
