如何在 Xcode Story Board 中添加有关多设备的动态字体大小

Question

我在storyBoard中添加了autoLayout（w：任意，h：任意）

但是由于字体大小固定，所有设备上的字体大小都是相同的 （4、4.7、5.5 英寸）

4英寸的看起来不错。但5.5寸的，太小了

我想在任何设备中动态增大和减小 UIlabel 字体大小。

有什么想法吗？

Answer 1

我找到了解决方案

我上了一节课

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，设置班级

然后，设置值

快乐编码！

Answer 2

检查屏幕尺寸并根据其操纵字体大小：

let screenSize = UIScreen.mainScreen().bounds.size

if screenSize.height < 568 {
    //Set font size for 4
} else if screenSize.height < 568 {
    //Set font size for 5
} else if screenSize.height < 568 {
    //Set font size for 6
} else {
    //Set font size for 6+
}

更新：

扩展 UILabel 类来设置您的标签：

extension UILabel { 
    func setupLabelDynamicSize(size size:CGFloat) {
        let screenSize = UIScreen.mainScreen().bounds.size

        if screenSize.height < 568 {
            //Set self.font equal size
        } else if screenSize.height < 568 {
            //Set self.font equal size + 1
        } else if screenSize.height < 568 {
            //Set self.font equal size + 2
        } else {
            //Set self.font equal size + 3
        }
    }
}

然后，无论你有一个想要动态大小的标签，只需调用：

labelObject.setupLabelForDynamicSize(size: 14)

Answer 3

不可以，您无法仅为 iPhone 5.5 配置尺寸类别。尺寸等级无法区分 iPhone 5、6 和 6Plus。

仅 1 个边缘保护壳仅支持 iPhone 5.5 横向：

regular width, compact height: 5.5" iPhone in Landscape

唯一的方法是检查代码中的设备大小！

Answer 4

动态标签文本大小和动态按钮文本大小：

这些标签和按钮的扩展

我修改了 Yoohogyun 答案以适合所有 iPhone 和 iPad，并且还预期新的屏幕尺寸：

使用 xcode 7.3，您可以在属性检查器中单击添加“+”来选择每个设备的字体大小
