Question

I have an UIWebView. After loading data to UIWebView, my UIWebView can scroll horizontally, and i enable paging for my scrollView in web view.

My question is:

is there any way to save a page in scrollView in UIWebView to image? I mean, i will get 5 images for 5 pages of scrollView(content size = 5 pages)

Answer 1

you can save your screen like this way:-

 -(IBAction)savebutn:(id)sender
 {
UIGraphicsBeginImageContext(self.view.bounds.size);
[self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *saveImage = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
NSData *imageData = UIImagePNGRepresentation(saveImage);
NSFileManager *fileMan = [NSFileManager defaultManager];

NSString *fileName = [NSString stringWithFormat:@"%d.png",imagename];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[fileMan createFileAtPath:pdfFileName contents:imageData attributes:nil];


 }

your Image will be save in your document directory with .png extension
