创建和管理常数的简单方法

通常，我首先声明常数，然后使用某种方法设置其设置。但是，编写一种声明常数和变量的简单方法是安全的吗？

例如，我创建了这样的方法 - 到目前为止可以正常工作：

func textSettings(labelName: String, text: String, color: UIColor, fontSize: Int, xPosition: CGFloat, yPosition: CGFloat) {
               
               let labelName = UILabel(frame: CGRect(x: 0, y: 0, width: 0, height: 21))
               labelName.textAlignment = .center
               labelName.text = text
               labelName.textColor = color
               labelName.font = labelName.font.withSize(CGFloat(fontSize))
               labelName.sizeToFit()
               labelName.layer.position.x = xPosition
               labelName.layer.position.y = yPosition
               UIScrollView.addSubview(labelName)
               
           }

但是使用它安全吗？创建对象的过程是否有严重的缺点？

Usually I first declare constants and then set their settings using some method. But is it safe to write a simple method that declare constants and variables?

For example, I create such method - that works fine up to now:

func textSettings(labelName: String, text: String, color: UIColor, fontSize: Int, xPosition: CGFloat, yPosition: CGFloat) {
               
               let labelName = UILabel(frame: CGRect(x: 0, y: 0, width: 0, height: 21))
               labelName.textAlignment = .center
               labelName.text = text
               labelName.textColor = color
               labelName.font = labelName.font.withSize(CGFloat(fontSize))
               labelName.sizeToFit()
               labelName.layer.position.x = xPosition
               labelName.layer.position.y = yPosition
               UIScrollView.addSubview(labelName)
               
           }

But is it safe to use it? Does such process of creating objects has serious drawbacks?

当您注意到这一点时，这是绝对可能的：

scrollview保留了对您新创建的标签的唯一引用。
也许更重要的名称，例如AddSetTingsLabel会更清楚。
也许分裂创建和使用是合适的，例如：

createSettingsLabel(labelName: String, text: String, color: UIColor, fontSize: Int, xPosition: CGFloat, yPosition: CGFloat) -> UILabel
{
...
}


let settingsLabel = createSettingsLabel(...)
scrollView.addSubview(settingsLabel)

This is absolutely possible, as soon as you note this :

The only reference to your newly created label is kept by the scrollView.
Maybe a more significant name like addSettingsLabel would be clearer.
Maybe splitting creation and use is suitable, like :

createSettingsLabel(labelName: String, text: String, color: UIColor, fontSize: Int, xPosition: CGFloat, yPosition: CGFloat) -> UILabel
{
...
}


let settingsLabel = createSettingsLabel(...)
scrollView.addSubview(settingsLabel)
