I want set dynamic height for webview depending on the dynamic text. I've tried
[my_webview sizeThatFits:CGSizeZero];
But it didn't work for me. I want to set webview height dynamically.
Thanx in advance.
See my answer to a similar question. The trick is to set the frame of the webView to a minimal height prior to sending -sizeThatFits:
.
Set up your web view as follows:
- (void)webViewSettings {
NSString *htmlString = @"Your HTML String";
NSString* descHtmlString = [NSString stringWithFormat: @"<html><meta name=\"viewport\" content=\"width=300, user-scalable=yes\" /><div style='width:300px' id='ContentDiv'><font face=\"Arial\" size=2.5 color='#702f70'>%@</font></div></html>", htmlString];
descHtmlString = [descHtmlString stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
[self.webView loadHTMLString:descHtmlString baseURL:[NSURL URLWithString:@""]];
}
Then implemented UIWebViewDelegate
in your interface file and the following method in the implementation file:
- (void)webViewDidFinishLoad:(UIWebView *)webView {
NSString *contentHeight = [self.descriptionWeb stringByEvaluatingJavaScriptFromString:@"document.getElementById('ContentDiv').offsetHeight"];
self.descriptionWeb.frame = CGRectMake(10,webView.frame.origin.y, 300, [contentHeight floatValue]);
}
