拍摄整个UIView的快照/屏幕快照-iPhone [英] Take snapshot / screenshot of whole UIView - iPhone

问题描述

我正在尝试截取UIView的屏幕快照/快照.我可以使用当前可见视图下面的代码获取屏幕截图-但是我需要整个视图.

I am trying to take a screenshot/snapshot of a UIView. I am able to get the a screenshot with the code below of the current visible view - but i am after the whole view.

该视图是滚动视图，因此下面没有我想被包含的内容

The view is a scrollview so there is content below that isnt visible that i would like to be included

如何扩展此代码以考虑不可见的视图?

How do i extend this code to take into account the view that isnt visible?

UIGraphicsBeginImageContext(activityView.frame.size);

[self.activityView.layer renderInContext:UIGraphicsGetCurrentContext()];

UIImage *fullScreenshot = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

UIImageWriteToSavedPhotosAlbum(fullScreenshot, nil, nil, nil);

推荐答案

iOS 7为类UIView引入了一种新方法.

There is a new method introduced from iOS 7 for a class UIView.

- (UIView *)snapshotViewAfterScreenUpdates:(BOOL)afterUpdates;
 - (UIView *)resizableSnapshotViewFromRect:(CGRect)rect afterScreenUpdates:(BOOL)afterUpdates withCapInsets:(UIEdgeInsets)capInsets;

您可以使用此方法拍摄当前视图的屏幕截图.

You can use this method to take screenshots of your current view.
