Swift（NSTextField|Swift：NSTextField 宽度自适应文字，自动换行） Swift：NSTextField宽度自适应文字

【Swift（NSTextField|Swift：NSTextField 宽度自适应文字，自动换行）】NSTextField 没有ios UILabel那么灵活可以自动换行，所有自己写了个方法，可以宽度自适应，上代码

func fitFontSize(maxSize : NSSize = NSSize.zero){ var text = self.stringValue var newSize = NSSize.zero self.sizeToFit() newSize = self.size var width = newSize.width; var height = newSize.height; let characterSize = width/CGFloat(text.count) if maxSize.width > 0{ if width > maxSize.width{ width = maxSize.width var count = Int(maxSize.width / characterSize) var array = text.components(separatedBy: " ") var newString = "" var heightCount = 1; if array.count > 1{ var currentCount = 0 for i in 0.. count{ newString += "\n" heightCount += 1; currentCount = 0 } newString += array[i] + " " currentCount += array[i].count + 1 } text = newString }else{ while count < text.count{ text.insert("\n", at: String.Index.init(encodedOffset: count)) count += count + 1 } } height = height * CGFloat(heightCount) } } self.stringValue = https://www.it610.com/article/text self.size = NSSize(width: width, height: height) }

传入固定宽度，自适应后的宽度大于固定宽度会自动换行，并调整高度。
