uiwebview

Does someone know of a way, or has a creative idea as to how to obtain an UIImage that is rendered from a UIWebView? The catch is, that is must be on a background thread. I'll elaborate: I'm trying to obtain the image from multiple UIWebViews every second+-, and display it on screen (iPhone's of course). Because rendering a layer to a CGContext is a CPU consuming job, I wouldn't like to use the main thread, so not to hang the UI. My attempts so far were: I tried to use renderInContext on the webView's layer to the UIGraphicalContext , but the _WebTryThreadLock error crashed the webviews. I

Is there any way to disable zooming when Scales page to Fit is ON ?? This works for me: UIScrollView *scrollView = [webView.subviews objectAtIndex:0]; scrollView.delegate = self;//self must be UIScrollViewDelegate - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return nil; } UPDATE: For iOS 5 or higher get scrollView like this: webview.scrollView.delegate = self; Instead of using UIScrollView *scrollView = [webView.subviews objectAtIndex:0]; scrollView.delegate = self;//self must be UIScrollViewDelegate - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView {

Before I begin, I should tell you that this only happens in iOS 5.1. Before the most recent update, this had never happened and it still does not happen on any other version. That said, here's what's going on. When a user logs out of my app, one of the things that happens is that all of the NSUserDefaults get deleted. Rather than manually removing every key I might add to the user's defaults, I just completely delete all of the NSUserDefaults , using the method suggested in this SO question : NSString *appDomain = [[NSBundle mainBundle] bundleIdentifier]; [[NSUserDefaults standardUserDefaults]

I'm trying to write an application which uses a lot of java script inside a UIWebView. And some of this java script is loaded dynamically (with jquery) when it is needed. The index.html and the jquery files are loaded as expected but not the code.js file. The code.js file is request like this (snipped of the java script code from index.html): function require(moduleName,filePath) { var uri = filePath; jQuery.ajax({ type: "GET", url: uri, async: false, dataType: "script", success: function(content) { console.log("Receive content of "+moduleName); }, error: function(XMLHttpRequest, textStatus,

I am using UIWebView to load a URL. Inside the page of that URL, it uses alert("whatever msg") as JavaScript. My UIWebView will pop up a window and show that alert message. Is there a way to disable this kind of popup window or JavaScript alert window? Add this after your web view has loaded its content [MyWebView stringByEvaluatingJavaScriptFromString:@"window.alert=null;"]; You can bind window.alert to another function. So: window.alert = function() { //does nothing so effectively "disables" alert }; Make sure you do this before you call any alerts. The neat thing about this is you can

I have simple UIWebView with loaded html. I want to show the PopoverView pointed to the selected text. I can get the menuFrame of the UIMenuController and use its rect, but the result isn't as accurate at the corners of the screen as I need. I can calculate the screen size and get menuFrame rect and then I can suppose where the selection may be found, but I want exactly know where is the selected text. Is it generally possible? hwaxxer You can use the javascript function getBoundingClientRect() on the range object of the selected text. This is how I do it: function getRectForSelectedText() {
