我尝试了一堆"解决方案"但是现在我试图找出UIWebView的scrollview的内容大小.它目前总是返回1024,这是设备的宽度.这是没有意义的,因为我正在查询高度,并且视图是纵向的.
以下代码报告高度为1024.00000
-(void)webViewDidFinishLoad:(UIWebView *)webView {
float sourcesWebViewHeight = [[webView stringByEvaluatingJavaScriptFromString:@"document.documentElement.scrollHeight"] floatValue];
NSLog(@"%f", sourcesWebViewHeight);
}

但我只有几行文字.
j_m*_*lly 11
我会分解最终为我解决的问题.
我不得不把我的内容包装在里面.
<html><head><meta name=\"viewport\" content=\"initial-scale=1, user-scalable=no, width=device-width\" /></head><body>%@</body></html>

实现以下视图确实加载.
-(void)webViewDidFinishLoad:(UIWebView *)webView {
[self layoutSubviews];
webView.scrollView.scrollEnabled = NO; // Property available in iOS 5.0 and later
CGRect frame = webView.frame;
frame.size.height = 1; // Set the height to a small one.
webView.frame = frame; // Set webView's Frame, forcing the Layout of its embedded scrollView with current Frame's constraints (Width set above).
frame.size.height = webView.scrollView.contentSize.height; // Get the corresponding height from the webView's embedded scrollView.
webView.frame = frame;
}

和
-(void) layoutSubviews {
[super layoutSubviews];
[body stringByEvaluatingJavaScriptFromString:
[NSString stringWithFormat:
@"document.querySelector('meta[name=viewport]').setAttribute('content', 'width=%d;', false); ",
(int)body.frame.size.width]];
}

最后我的webview做了所有正确的事情来扩展自己的内容.
