Swift Xcode通过切换将标签快速增加1，并保存切换值
我将非常感谢任何反馈或见解，以帮助解决我面临的最后一个问题。我的代码太大了 我有4个开关。打开时的每个切换都会导致标签增加1。我还成功地在关闭和重新打开应用程序时保存了切换位置和标签。但是，当我关闭并重新打开应用程序，然后切换其中一个开关时，标签会返回到1 我理解代码的编写方式，它认为其他三个开关=0，并使标签显示为1 有没有一种方法可以让我在每一帧都运行一个函数，不断检查哪些开关处于打开/关闭状态，然后在标签中返回该值，同时在我打开和关闭应用程序时保存所有信息。下面是图片和我的代码Swift Xcode通过切换将标签快速增加1，并保存切换值,swift,switch-statement,toggle,increment,Swift,Switch Statement,Toggle,Increment,我将非常感谢任何反馈或见解，以帮助解决我面临的最后一个问题。我的代码太大了 我有4个开关。打开时的每个切换都会导致标签增加1。我还成功地在关闭和重新打开应用程序时保存了切换位置和标签。但是，当我关闭并重新打开应用程序，然后切换其中一个开关时，标签会返回到1 我理解代码的编写方式，它认为其他三个开关=0，并使标签显示为1 有没有一种方法可以让我在每一帧都运行一个函数，不断检查哪些开关处于打开/关闭状态，然后在标签中返回该值，同时在我打开和关闭应用程序时保存所有信息。下面是图片和我的代码 impor
