I am working in iPhone 4.3 environment. My requirement is that I design the html page with a file upload feature, and I need to include this html file into the webview. By selecting the upload button, I need to browse my device photos and videos, so that I can upload into the server.
Is that possible? It would be really helpful if I could get any working samples.
It's possible.But you can not use the webkit DOM because it's not available for iOS.
My solution is:
click html button, call javascript to change the value of window.location.hash e.g. window.location.hash="uploadImg;uploadUrl";
using -(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType to monitor the change of hash code attached to current url; if "uploadImg;uploadUrl" is found in the current url, invoke the native objective-c code to browse photo or take new picture and upload the picture to url specified by uploadUrl;
when upload is done, native code could call javascript by
NSString *markupResult = [webView stringByEvaluatingJavaScriptFromString:@"callback_javascript_upload()"];
It's possible to do what you looking for.
In your html code , your upload button should call javascript that will call your browsing photos and video objective-c code
The technique is calling objective-c code from javascript , see also : WebKit DOM Programming Topics here.
