如何拍摄UIWebView控件的快照/屏幕截图？

Answer 1

接受的答案是正确的，但屏幕截图不是视网膜分辨率。使用UIGraphicsBeginImageContextWithOptions并将其缩放参数设置为0.0f使其以原始分辨率捕获。

UIWindow *keyWindow = [[UIApplication sharedApplication] keyWindow];
CGRect rect = [keyWindow bounds];
UIGraphicsBeginImageContextWithOptions(rect.size,YES,0.0f);
CGContextRef context = UIGraphicsGetCurrentContext();
[keyWindow.layer renderInContext:context];   
UIImage *capturedScreen = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Answer 2

使用此：

UIGraphicsBeginImageContext(rect.size);
[webView.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

Answer 3

使用此代码截取屏幕截图并将其保存到库中

    UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIImageWriteToSavedPhotosAlbum(viewImage, self, nil, nil);

您可以通过更改

来更改屏幕截图

UIGraphicsBeginImageContext(self.view.bounds.size);
