问题 I'm using goNative.io to run my webapp in a wrapper/native iOS app. I'm adding bit of extra objective-c that reads the contents of HTML5 local storage and persists the data in the app when it's exited. Also, when the app opens back up I need to put that data back in local storage. My issue is that stringByEvaluatingJavaScriptFromString:jsString does not seem to run any javascript in my app. I can try to alert or console.log something and absolutely nothing happens in UIWebView . No errors

问题 So I successfully retrieved my BLOB image from the database and set it to NSData *content.. content = [[NSData alloc] initWithBytes:sqlite3_column_blob(query, 16) length:sqlite3_column_bytes(query, 16)]; What I am trying to do is to get this content into a NSString, because I would like to then pass this string to javascript and display the image. I am not exactly sure if this is even possible, but i have read on the link below that you can display images in css/html in base64. http://mark

问题 I try to distinguish an Iphone 5 device in a non full screen UIWebview (320x216) from javascript. I am using the screen height as switch as that seems the only way to do this in javascript. The problem is that the usual way to do this reports either 0 or the height of the UIWebview , not the height of the device. document.body.offsetHeight //returns 216 screen.availHeight //returns 0 document.documentElement.clientHeight //returns 216 window.innerHeight //returns 216 screen.height //returns 0

问题 My app is primarily loading text-based HTML files into a UIWebView . When a new HTML file is loaded, I'd like it to be read in its entirety to VoiceOver users. Right now, it reads only the headings within <h1> tags, and then stops. It works great if I double finger swipe down. I'd really just like to automate that process upon each new page load. Right now I'm using the following within webViewDidFinishLoad : UIAccessibilityPostNotification(UIAccessibilityScreenChangedNotification, self

问题 I have walked through various solution to clear the local image cache in UIWebView, while i trying to load the image in html it atomically displays the previous image(i using the same name to replace the image in template). [[NSURLCache sharedURLCache] removeAllCachedResponses]; NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL:[NSURL fileURLWithPath:[[CustomFunctions getFilesPath] stringByAppendingPathComponent:obj]] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData
