推荐答案

最好的方法是将整个应用程序组件放在一个scrollview中并使用缩放控件。

The best way to do it, is to put the entire app components in one scrollview and use the zooming of the control.

另一种不如第一种方式稳定的方法是根据捏缩放比例缩放UIVIEW内的所有对象，但请记住，缩放会影响整个应用程序的外观，因此您需要相应地调整每个对象的位置。

The other way which is not as stable as the first one, is to scale all objects inside the UIVIEW larger or smaller depending on the pinch zoom, but keep in mind that scaling will affect the look of the entire application, so you need to adjust the position of each object accordingly.
