UITextView 字体总是固定大小 [英] UITextView font to always be fixed size

问题描述

我有一个 UICollectionView 单元格的大小与 a4 页面的纵横比相同.对于不同的屏幕尺寸，我希望该文本的大小固定为 12pt(将计算到 UICollectionview 单元格)，这在 iPad 上看起来更大，在 iPhone 上看起来更小.

I have a UICollectionView with cells sized to the same aspect ratio as a4 page. And with different screen sizes I would like for that text to be sized at fixed 12pt (that would be calculated to that UICollectionview cell), which would look bigger on the iPad and smaller on iPhone.

所以固定字体大小不是一种选择......

So having a fixed font size isn't an option...

推荐答案

编码

var fontSize : CGFloat = 12.0 // DEFAULT SIZE

在您的 ViewDidLoad

In your ViewDidLoad

if UIDevice().userInterfaceIdiom == .phone {
    switch self.view.frame.size.height {
    case 480:
        fontSize = 12.0
    case 568:
        fontSize = 14.0
    case 667:
        fontSize = 16.0
    case 736:
        fontSize = 17.0
    case 812:
        fontSize = 18.0
    default:
        print("unknown")
    }
}
else if UIDevice().userInterfaceIdiom == .pad {

    fontSize = 20.0

}

然后在您需要的任何地方应用此 fontSize.

Then apply this fontSize, wherever u need.
