问题 I've been trying to display a xml file in my uiwebview. I've tried using NSURLRequest but the UIWebview shows up blank. I am able to display a local xml using the code below. Is there a way pull this from a defined website rather than from local file or maybe download the file then display it? NSString *htmlFile = [[NSBundle mainBundle] pathForResource:@"location" ofType:@"xml"]; NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile]; [aWebView loadData:htmlData MIMEType:@"text/text"

问题 I am facing a problem with UIWebView .

I have successfully gotten a function to be called inside that class file upon launching, but when I add the the code to create the webview to that function, I am getting errors like this: " Tried to obtain the web lock from a thread other than the main thread or web thread. This may be the result of calling to UIKit from a secondary thread. Crashing now... " My code to create the UIWebView is

问题 I'm using a UIWebView to display formatted text from local HTML. Is it possible to have specific links in the HTML call Obj-C functions? For example, clicking a link to have a new view appear? Or am I resigned to using Javascript? 回答1: You can use UIWebViewDelegate:shouldStartLoadWithRequest:navigationType: to intercept the URL and do something with it. E.g. if ([[request.URL absoluteString]compare:@"http://somelink"] == NSOrderedSame) { [self someFunction]; return YES; // return NO to

问题 During the development of my iPhone app, I decided to integrate Google Maps by including a UIWebView with a URL I construct pointing to maps.google.com. The problem is that the website tries to get the user's location, displaying the "This app wants to use your location". This creates a number of issues for me, which I can explain if necessary. Is there any way to disable the UIWebView / Mobile Safari from asking for the user's location. The only workaround I can think of is to use Google's

问题 For some reason, I need to get the caret vertical position in a content editable UIWebView. As many methods to do that stop caret blinking (for example when creating/removing a hidden node), I use this javascript/Objective-C code: - (CGRect)caretRect { NSString *js = @"function f(){ var sel = document.getSelection(); var range = sel.getRangeAt(0).cloneRange(); range.collapse(true); var r =range.getClientRects()[0]; return '{{'+r.left+','+r.top+'},{'+r.width+','+r.height+'}}'; } f();";

问题 Is there a way to download an entire webpage for offline viewing with the iPhone SDK? I can use NSString with the contents of the URL, but that would just give me the HTML and no images. Is there any way to do it? 回答1: The popular open source library ASIHTTPRequest has a class that will do just this for you: download all HTML, images, and other resources associated with the page you're requesting. It's called ASIWebPageRequest , and you can read the documentation and download it from here:

问题 I need to be able to get a path to images that cached. While I am wondering if there is a way to do this using SDWebImage, I could probably get away with just having the knowledge to return a path to an image stored in the cache so I can display it within a uiwebview inside an image tag. 回答1: According to this https://github.com/rs/SDWebImage/issues/25 it would seem you can simply refer to the image by it's original url and it will be correctly picked up from cache. 来源： https://stackoverflow
