Question

我只需要界面构建器的帮助。我试图只旋转我的应用程序的标签，但我无法找到任何旋转功能..

任何人都可以帮我旋转标签，我是否需要在xcode中旋转代码？

Answer 1

我认为你不能在IB中旋转它。您需要将变换应用于视图以使其旋转。

view.transform = CGAffineTransformMakeRotation(3.14/2);

Answer 2

In Swift 4, add the following code to your View Controller:

@IBDesignable
class DesignableLabel: UILabel {
}

extension UIView {
    @IBInspectable
    var rotation: Int {
        get {
            return 0
        } set {
            let radians = ((CGFloat.pi) * CGFloat(newValue) / CGFloat(180.0))
            self.transform = CGAffineTransform(rotationAngle: radians)
        }
    }
}

Then in interface builder, change your label class type in the Identity Inspector to "DesignableLabel". Your label should then be rotatable in interface builder.

在Interface builder中将label旋转到横向
