问题 I need to check if a webview when completed loading has any content or not. What I require is simple. Its a small webview strip at the bottom of my pages (like an advert) I call NSURLRequest *request=[NSURLRequest requestWithURL:adURL]; [gWebView loadRequest:request]; I get the callback -(void)webViewDidFinishLoad:(UIWebView *)webView { But in my scenario the webview shall return empty and sometime it shall have data.

问题 For some reason, I cannot get a UIWebView to "play nice" with my new Retina images. The issue, step-by-step: I am loading a series of HTML help files out of the bundle. My code loads different HTML files if it's an iPhone 4 ( LWERetinaUtils below is a util class I have written). I have read in this question that it is not possible for the UIWebView to auto-detect the @2x indicator - and experienced that personally, hence this approach. if ([LWERetinaUtils isRetinaDisplay]) htmls = [NSArray

问题 I have a long HTML document that contains multiple paragraphs. When I try to select the text either in Mobile Safari on iOS or in a UIWebView, the following happens: At first, I get character-level precision on my selection. Then, as I select more, the precision drops to two lines of text and eventually to whole paragraphs. There is no way to end my text selection exactly where I want.

It seems as if I need to LIMIT the amount of text I can put on a certain page. Is there a function to LIMIT the input of a
