I am add UIWebView in View and That view in ScrollView.
I want to get frame of the UIWebView Content. So can I set the frame to view and scrollview?
I know we can get the height by using javascript. As mention below:
float height = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] floatValue];
But when I am rotating the view and recalculate the height of the UIWebView content in didRotateFromInterfaceOrientation::(UIInterfaceOrientation)fromInterfaceOrientation
method, then content height was increased.
So please suggest me how can I get the proper height when i am rotate the orientation?
Thanks.
Adopt this method:
- (void) webViewDidFinishLoad:(UIWebView *)webView{
CGRect frame = wvContent.frame;
CGSize fittingSize = [wvContent sizeThatFits:CGSizeZero];
frame.size = fittingSize;
wvContent.frame = frame;
}
Then call this method everytime device rotating:
- (void) reloadContent
{
CGRect frame = wvContent.frame;
frame.size.height = 1;
frame.size.width = wvContent.frame.size.width; // you should change webview's width here.
wvContent.frame = frame;
[wvContent loadHTMLString:yourHTML baseURL:nil]; // reload webview
}
Hope that help :)
Make sure that you are retrieving height when all the content is loaded.
You can add a method to calculate height in UIWebView
's delegates method
- (void)webViewDidFinishLoad:(UIWebView *)webView{
float height = [[webView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] floatValue];
}
