我在storyBoard中添加了autoLayout(w：Any,h：Any)
但由于字体大小固定,所有设备的字体大小都相同
(4,4.7,5.5英寸)
4英寸看起来不错.但在5.5英寸,这太小了
我想在任何设备中动态地发布和减少UIlabel字体大小.
有任何想法吗？
解决方法
我找到了解决方案
我做了一堂课
class UILabelDeviceClass : UILabel {
@IBInspectable var iPhoneFontSize:CGFloat = 0 {
didSet {
overrideFontSize(iPhoneFontSize)
}
}
func overrideFontSize(fontSize:CGFloat){
let currentFontName = self.font.fontName
var calculatedFont: UIFont?
let bounds = UIScreen.mainScreen().bounds
let height = bounds.size.height
switch height {
case 480.0: //Iphone 3,4,SE => 3.5 inch
calculatedFont = UIFont(name: currentFontName,size: fontSize * 0.7)
self.font = calculatedFont
break
case 568.0: //iphone 5,5s => 4 inch
calculatedFont = UIFont(name: currentFontName,size: fontSize * 0.8)
self.font = calculatedFont
break
case 667.0: //iphone 6,6s => 4.7 inch
calculatedFont = UIFont(name: currentFontName,size: fontSize * 0.9)
self.font = calculatedFont
break
case 736.0: //iphone 6s+ 6+ => 5.5 inch
calculatedFont = UIFont(name: currentFontName,size: fontSize)
self.font = calculatedFont
break
default:
print("not an iPhone")
break
}
}
}
然后,设置类
然后,设定价值
快乐的编码！
