问题 How to avoid an UIWebView from opening the iTunes App when loading an iTunes URL? Example URL: http://itunes.apple.com/nl/app/bluppr-postcards/id348147229?mt=8 Above URL loads the iTunes App directly. UIWebViewDelegate doesn't seem to be able to control this to just load the page in the UIWebView. It seems it's controlled by the JavaScript function detectAndOpenItunes(); in the body tag of the page. Any ideas? 回答1: You're right that the relevant function is detectAndOpenItunes(), which is

问题 I need to check the response status code while loading any of the url in the webview fo.

问题 I am new to iOS development. I will try my best to explain my question, please pardon me if you find it silly. I was wondering if one can load a subview in a UINavigationController by clicking a link inside a UIWebView. Explaining it further, let's say there is UINavigationController that has a subview and that subview has a UIWebView called A, and there is another subview(that is not loaded yet) called B. Is is possible to load B (or perform any other native Objective C event) when user taps

问题 I am trying to dynamically create a UIWebView inside a class file upon launching the application. I have successfully gotten a function to be called inside that class file upon launching, but when I add the the code to create the webview to that function, I am getting errors like this: " Tried to obtain the web lock from a thread other than the main thread or web thread.

问题 I'm testing a UIWebview with a number of different document types - .xlsx, .jpg, etc. - and it opens most of them just fine. From time to time, I open a local file and this message appears right in the web view: Unable to Read Document An error occurred while reading the document I'm not concerned with "why" this error occurs - it happens, for instance, when I feed the UIWebView a garbage file (intentionally). The problem is that I can't figure out how to detect "when" this happens. It doesn

问题 I am trying to load a UIWebView with the Facebook OAuth authorization URL and I am using the following code. When my UIWebView loads with Facebook login page, I enter my credentials, then press the "Log in" button. When I hit the button I am getting the following error: WebKit discarded an uncaught exception in the webView:decidePolicyForNavigationAction:request:frame:decisionListener:delegate: Application tried to present modally an active controller .

问题 I have an app where users can navigate a pile of locally stored HTML files. I have a UIWebView , configured up correctly with a UIWebViewDelegate .
