UIWebView respond to Javascript calls

由 老子叫甜甜 提交于 2019-11-30 10:46:46
How can I intercept Javascript calls such as window.open as Mobile Safari does? I haven't seen anything listed about this, but it must be possible somehow? Has anyone done this before? FKDev When the page is finished loaded (webViewDidFinishLoad:), inject a window.open override. Of course it will not work for window.open which are called during page load. Then use a custom scheme to callback your objective C code. [EDIT] OK I have tested it. Now it works. Create a new "view based" project and add a webview in the viewcontroller xib using IB. @implementation todel2ViewController // Implement

Scrollable div on iPhone without using 2 fingers?

由 ▼魔方 西西 提交于 2019-11-30 10:25:57
I've got a UIWebView embedded in my iPhone app, and I'd like to keep a locked header and footer DIV on the page at all times, with a scrollable center DIV. I know that I could do this using a header/footer that are UIView controls, but I want the header and footer to be HTML divs, as a pure HTML/JS/CSS solution will be easier to port to Android/PalmPre/AdobeAir, which is going to be on my todo list relatively soon. I can do this using techniques like the one mentioned here: http://defunc.com/blog/?p=94 But this requires that the user use 2 fingers to scroll the div, which is not satisfactory

uiwebview and huge memory loss

由 喜夏-厌秋 提交于 2019-11-30 09:12:39
I have a problem using UIWebViews, I've seen the same question here but there wasn't helpful answer. the question is here: UIWebView memory management . I will quote it: I am developing an application that makes heavy use of UIWebView. This app generates dynamically lots of UIWebViews while loading content from my server. Some of these UIWebViews are quite large and have a lot of pictures. If I use instruments to detect leaks, I do not detect any. However, lots of objects are allocated and I suspect that has to do with the UIWebViews. When the webviews release because no longer needed, it

set a delegate for UIWebView

由 萝らか妹 提交于 2019-11-30 08:49:56
How do I set a delegate for my UIWebView to use webViewDidFinishLoad ? Matthew Frederick In the interface file indicate that you're interested: @interface SomethingController : UIViewController <UIWebViewDelegate> { Then in your implementation you'll add that delegate method: - (void)webViewDidFinishLoad:(UIWebView *)webView { // Do whatever you want here } Obviously SomethingController should be your actual controller, and UIViewController is whatever you're actually implementing. This, by the way, is basically how you implement any delegate. Edit In a window-based app, assuming your

Clearing UIWebView's Cache in Swift

由 走远了吗. 提交于 2019-11-30 08:40:32
I have a UIWebView inside my app. This UIWebView needs to be reloaded fully (i.e. clear all cache of images/HTML/cookies etc.) every time when viewDidLoad . So is there any code I can do this in Swift? Here is my code: let myUrl = NSURL(string: "http://www.example.com") let myRequest = NSURLRequest(URL: myUrl!) myWebView.loadRequest(myRequest) Thanks! rakeshbs You can use NSURLCache.sharedURLCache().removeAllCachedResponses() NSURLCache.sharedURLCache().diskCapacity = 0 NSURLCache.sharedURLCache().memoryCapacity = 0 Swift 3.0 URLCache.shared.removeAllCachedResponses() URLCache.shared
