关闭 UIScrollView 中的缩放

问题描述

有谁知道在使用 UIScrollView 时暂时关闭缩放的方法?

Does anyone know a way to temporarily turn off zooming when using a UIScrollView?

我发现您可以使用以下方法禁用滚动:

I see that you can disable scrolling using the following:

self.scrollView.scrollEnabled = false;

但我没有看到类似的缩放命令.有什么想法吗?

but I'm not seeing a similar command for zooming. Any thoughts?

推荐答案

如果您想禁用用户通过手势缩放的能力，那么在 iOS 5 及更高版本中，您可以禁用捏合手势.这仍然允许您从代码中控制滚动视图...

If you want to disable the user's ability to zoom through gestures then in iOS 5 and above you can disable the pinch gesture. This still allows you to control the scroll view from code...

scrollView.pinchGestureRecognizer.enabled = NO;

对于泛...

scrollView.panGestureRecognizer.enabled = NO;

这必须在 - (void)viewDidAppear:(BOOL)animated 或更高版本中调用，否则系统会将其重置为启用.

This must be called in - (void)viewDidAppear:(BOOL)animated or later as otherwise the system resets it to enabled.

Swift 4.x 及更高版本:

imageZoomView.pinchGestureRecognizer?.isEnabled = false/true
