Question

I want to download html content, then find out it’s size (by calling javascript functions). After that I want to change UIWebView frame to that size. And html content should fill whole UIWebView.

I read documentation and similar questions here on stackoverflow. Nothing helped. I don’t want to call reload method and download HTML from server twice. I get correct width and height of html, but after changing UIWebView frame size, html content doesn’t fill the frame. (this code below is called in - (void)webViewDidFinishLoad:(UIWebView *)webView)

NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber *width = [f numberFromString:[self.mediaWebView stringByEvaluatingJavaScriptFromString:@"getContentWidth()"]];
NSNumber *height = [f numberFromString:[self.mediaWebView stringByEvaluatingJavaScriptFromString:@"getContentHeight()"]];

self.mediaWebView.frame = CGRectMake(BORDER_WIDTH, BORDER_WIDTH, _frameWidth, _frameHeight);
self.mediaWebView.bounds = CGRectMake(0, 0, _frameWidth, _frameHeight);

Init code:

self.mediaWebView = [[UIWebView alloc] initWithFrame:CGRectMake(BORDER_WIDTH, BORDER_WIDTH, _frameWidth, _frameHeight)];
[self.mediaWebView setBackgroundColor:[UIColor clearColor]];
[self.mediaWebView setOpaque:FALSE];
[self.mediaWebView setUserInteractionEnabled:TRUE];
self.mediaWebView.scrollView.scrollEnabled = FALSE;
self.mediaWebView.scrollView.bounces = FALSE;
self.mediaWebView.delegate = self;
self.mediaWebView.contentMode = UIViewContentModeRedraw;
self.mediaWebView.backgroundColor = [UIColor blackColor];


NSString *stringUrl = @""// some URL

NSURL *url = [NSURL URLWithString:stringUrl];
[self.mediaWebView loadHTMLString:[self.questionView.question.mediaHtml description] baseURL:url];

self.mediaWebView.scalesPageToFit = TRUE;

[self addSubview:self.mediaWebView];

Answer 1

As I described in comment below question. It was enaugh to set scalesPageToFit to FALSE
