Get notified about a page change in UIWebView

阅读更多关于 Get notified about a page change in UIWebView

问题 I'm curious if there's a way to detect a change of the displayed website inside a UIWebView . In an app I'm working on we're using a UIWebView to present a part of the functionality which are basically a few steps the user needs to follow. However, the will be a specific page at the end of these steps that I need to identify and after which the app needs to display a different view. Unfortunately the UIWebViewDelegate doesn't seem to do the trick. 回答1: If the user steps are separated on

阅读更多关于 Using a UIWebView, can I use a custom font?

问题 I've seen all the talk on the web about the difficulty of using a custom font in iPhone OS. Is it possible, to load a font from within my bundle into the UIWebView component? EDIT: I saw it in the app called "Omer" by "Rusty Brick"... It seems to be a web view, because I see a delay and during the loading delay the custom area is white. What other component could this have been? EDIT2: I contacted Rusty Brick. They told me which font it was. A standard font. 回答1: It is possible to load custom

How to block Javascript alert|confirm|promt in UIWebView before render completed?

阅读更多关于 How to block Javascript alert|confirm|promt in UIWebView before render completed?

There are multiple questions on SO already addressing similar issues but none answers my exact type of question. Most of the answers involves running a JS snippet and overloading the alert method as such: window.alert = function() {}; The problem I am having is that the webpage loaded (which I have no control over the content) opens an alert before the rendering of the whole page completes. Because of this I cannot use the: - (void)webViewDidFinishLoad:(UIWebView *)webView delegate method to run the JS snippet. In addition running the same snippet in - (void)webViewDidStartLoad:(UIWebView *

Cross-Platform Way of Creating Safari Webarchives

阅读更多关于 Cross-Platform Way of Creating Safari Webarchives

I've been searching around and haven't found any reference to tools that can create Safari's webarchive format. Does anyone have pointers to code for creating this format, or at least a format reference documentation? Ideally I'd like to build a tool that takes a directory and splits out a webarchive, for loading into a iPhone. To expand on what Ben said: CFLite (the cross-platform open-source subset of Core Foundation) ships with a plist parser. If you can link against that, it should be quite simple to work with .webarchive files, which are simply property lists that concatenate all files

问题 I'm working with the new facebook-ios-sdk and have successfully integrated the api into my native app. I am able to authenticate a user and properly setup permissions using a popup dialog with the ios-sdk classes. For a portion of my app I need to use the facebook connection within a UIWebView , using javascript and html to process data within the webview.

阅读更多关于 Frame load interrupted error while loading a word document in UIWebView

I want to load a word document using UIWebView. I used the code provided in http://developer.apple.com/iphone/library/qa/qa2008/qa1630.html to load the document. But not all the documents load successfully. Sometimes I get an error Error Domain=WebKitErrorDomain Code=102 UserInfo=0x145bc10 "Frame load interrupted" The error seems to be very sporadic and I get this error only for some documents. However the same document loads correctly in mail.app. What am I missing? The reason was, the file I tried to load doesn't contain a extension. I was purposely removing the file extension (.doc and .ppt

How to access image resource in asset catalog from UIWebView (or WKWebView)

阅读更多关于 How to access image resource in asset catalog from UIWebView (or WKWebView)

We have a local html to show in UIWebView . And there, we want to show images that are defined in Asset Catalog. I know that we can do similar thing if we had the image flat in the main bundle. The code snippet would be like this. webView.loadHTMLString("<img src='target_image.png'/>", baseURL: NSBundle.mainBundle().bundleURL) However, I am not sure what I can specify for "target_image.png" if the png file is packaged in asset catalog. (Furthermore, we want to specify pdf to take advantage of vector image support in Xcode 6) Does anybody have any idea how to achieve this? Since the asset
