我在 UIscrollview 中放置了一个 Uiwebview,因为在 uiwebview 之后我想用 PageController 显示一些图像。
我正在使用这行代码。
-(void)webViewDidFinishLoad:(UIWebView *)webView{
if (webView!=WebView)return;
float h;
NSLog(@"web view is %f high", WebView.frame.size.height);
NSString *heightString = [WebView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"body\").offsetHeight;"];
NSLog(@"web content is %@ high",heightString);
h = [heightString floatValue] +12.0f;
WebView.frame = CGRectMake(WebView.frame.origin.x, WebView.frame.origin.y, WebView.frame.size.width, h);
h = WebView.frame.origin.y + h + 20;
[ScrollView setContentSize:CGSizeMake(320, h)];
}
但Web view is %f high
不起作用,它不会重新调整 WebView 的高度有谁知道我该如何解决这个问题?这是因为我正在使用[WebView loadHTMLString:html baseURL:nil];
和:NSString *heightString = [WebView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"body\").offsetHeight;"];
NSString *html = [NSString stringWithFormat:@"<html><head><!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01//EN\" \"http://www.w3.org/TR/html4/strict.dtd\"><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" /><style>body { font: normal 13px helvetica; color: #565656; } </style></head><body><p>%@</p></body></html> ",text];
[WebView loadHTMLString:html baseURL:nil];
