我正在创建标签和字符,我想要按字符设置UILabel的框架(X,Y和宽度),Y轴是所有设备的常量,那么如何设置X轴的中心并按计数控制字符和宽度(50)每个设备变得越来越小?
这是我的代码:
func createTarget(id: Int) {
listdata = dbHelpr.getDatabase(rowId: id)
for data in listdata {
let lengthOfChar : CGFloat = data.ans.length
let targetSize : CGFloat = self.view.frame.width / 2
var xAxis : CGFloat = self.view.frame.width / 2 + 55
let yAxis : CGFloat = self.view.frame.height / 2 + 70
let targetLabel = UILabel(frame: CGRect(x: xAxis, y: yAxis, width: 50, height: 5))
xAxis -= 50 + (lengthOfChar)
}
}
在这张图片中是我的标签,它的位置是iPhone 7加上模拟器的X轴中心和每个字符数的标签数量,所以我希望所有设备和宽度都有这个位置(X,Y和宽度)变小和变大,如果字符数为9,则必须在X轴的中心,宽度必须小一些,并且设备的左右空间。
我该怎么做?!
谢谢:)

这是解决方案:
func createTarget(id: Int) {
listdata = dbHelpr.getDatabase(rowId: id)
for data in listdata {
let lengthOfChar : CGFloat = data.ans.length
let yAxis : CGFloat = self.view.frame.height / 2 + 70
let width: CGFloat = view.frame.size.width - 40 // frame width
var targetWidth: CGFloat = (width - (lengthOfChar - 1) * 5) / lengthOfChar
if targetWidth > 50 {
targetWidth = 50
}
let totalWidth: CGFloat = (targetWidth * lengthOfChar) + ((lengthOfChar - 5) * 5)
for (indexTar, tar) in data.ans.characters.enumerated() {
let x : CGFloat = (width / 2) - (totalWidth / 2)
let xx : CGFloat = (CGFloat(indexTar) * targetWidth) + (CGFloat(indexTar) * 5) + 20
var xAxis : CGFloat = (x + xx)
xAxis = width - xAxis
let targetLabel = UILabel(frame: CGRect(x: xAxis, y: yAxis, width: targetWidth, height: 5))
targetLabel.backgroundColor = .white
targetLabel.layer.masksToBounds = true
targetLabel.layer.cornerRadius = 5
targetLabel.text = String(describing: tar)
targetLabel.textAlignment = .center
targetLabel.textColor = .white
self.view.addSubview(targetLabel)
}
}
}
