推荐答案
您可以通过注册通知来检测更改 _UIClassicApplicationWillChangeZoomNotificationName 然后使用或多或少的@magma在他的回答中概述的方法来处理规模变化。 _UIClassicApplicationWillChangeZoomNotificationName 会告诉您何时使用2x/1x按钮更改比例。
You can detect the change by registering for the notification _UIClassicApplicationWillChangeZoomNotificationName and then handle the scale change using more or less the method outlined by @magma in his answer. _UIClassicApplicationWillChangeZoomNotificationName will tell you when the "2x"/"1x" button has been used to change the scale.
