问题 I use a web view to display small pdf files. In the interest of aesthetics, I'd like to remove the grey border around the PDF. Is there any way around it? I've looked at various resources none of which seem to work or the solution no longer works in iOS5. Also, is there any way of stopping the scroll if there's only one page?

问题 I'm working on an app that has table navigation to eventually drill down to UIWebView that displays various information. However, the transition from the slickness of UITableView to the slow wonkiness of UIWebView is jarring for the user so I want to improve that experience however I can. Specifically, the background of both the tableViews and UIWebView pages have black backgrounds, but when I open the UIWebView it flashes empty white for about a second (this is the case for both local and

问题 i have a UIWebView which acts like an internet browser and loads the HTML of the webpages that it is at. in the webViewController, the method webViewDidFinishLoad, would have loaded the HTML from the webpage when the webpage finish loading on the UIWebView.

问题 so I have UIWebView in my application and I load some html (article) to it, put some CSS to make everything nicer. That's simple and clear and everything is perfect until I try to add reading in landscape functionality and then I've noticed that UIWebView ignores any css "font-size" I've put in HTML and increases font size drastically after rotating to landscape mode.
