如果UIView在窗口范围之外，则来自UIView的UIImage

[英]UIImage from UIView if UIView is outside window bounds

原文 2014-06-19 13:10:57 5 1 ios/ objective-c/ uiview/ uiimage

I have UIScrollView with many UIView views added to the content. 我有UIScrollView，其中许多UIView视图已添加到内容中。 I would like to convert UIView and its subviews to UIImage and I know how to do it if the UIView is currently visible on the device screen. 我想将UIView及其子视图转换为UIImage，并且如果UIView当前在设备屏幕上可见，我知道该怎么做。 Is it possible to convert UIView (subview in UIScrollView) into UIImage if UIView is not in UIScrollView visible rect? 如果UIView不在UIScrollView中，是否可以将UIView（UIScrollView中的子视图）转换为UIImage？

1 个解决方案

Could you just iterate over all subviews taking a screenshot of each UIView inside the UIScrollView ? 您是否可以对所有子视图进行迭代，为UIScrollView中的每个UIView截屏？

The following class may help with taking screenshots: http://ioscodesnippet.com/2011/08/25/rendering-any-uiviews-into-uiimage-in-one-line/ 以下课程可能有助于截图： http : //ioscodesnippet.com/2011/08/25/rendering-any-uiviews-into-uiimage-in-one-line/

Hope you find a solution. 希望您找到解决方案。
