uiwebview

问题 I have a UIViewController that contains a UIWebView (OS 3.0). If I load it with file data, as soon as the 'Back Button' is hit and the view is dismissed, I'm seeing EXEC_BAD_ACCESS error with WebCore object releasing 'SharedBuffer' - (void)viewDidLoad { NSString *htmlFile = [[NSBundle mainBundle] pathForResource:fileName ofType:@"html"]; NSData *fileHtmlData = [NSData dataWithContentsOfFile:htmlFile]; [webView loadData:fileHtmlData MIMEType:@"text/html" textEncodingName:@"UTF-8" baseURL:

问题 I would like to show Content in the UIWebView, which I have added to the Project. (for example an image) I know how to set a text in the UIWebView, but I would like to add images or a video which I have added to the project. 回答1: Ok, I am assuming you are using loadHTMLString to set the HTML on your UIWebView . So to reference images that are stored in your App bundle, you just need to get the right path to put in your img tag. So get the path string: NSString * imgPath = [[NSBundle

问题 I have a UIWebView which loads a local index.html file. However I have an external link in this html file that I'd like to open in Safari instead of internally in the UIWebView . Opening a link in safari from say a UIButton was simple enough: UIApplication.sharedApplication().openURL(NSURL(string: "http://www.stackoverflow.com")) Opening the Instagram app from a external link also works like a charm. <a href="instagram://media?id=434784289393782000_15903882">instagram://media?id

问题 I have a mainView that contains : a paginated scrollView, a page Control a close button and each page of the scrollView contains a subview that contains a webView. The user can go left to right from pages to pages, and scroll up and down each webView. But... how can I make the currently displayed webView scroll to top when the user touches the status bar ? EDIT : for iOS4 of course. 回答1: [yourPaginatedScrollView setScrollsToTop:NO]; [(UIScrollView *)[yourWebView.subviews objectAtIndex:0]

问题 I have the following sample code (using ARC) which adds a UIWebView as a subview and subsequently removes it (toggled by a tap gesture on the screen): - (void)toggleWebViewLoading:(UITapGestureRecognizer *)sender { if (webView == nil) { webView = [[UIWebView alloc] initWithFrame:CGRectMake(0.0f, 100.0f, [UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height - 100.0f)]; [webView loadRequest:[[NSURLRequest alloc] initWithURL:[[NSURL alloc] initWithString:@"http://www

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I have a an Xcode project with UIWebView . Now I need to load an image from document directory to that webview. How can I acheive this? 回答1: NSArray *paths=NSSearchPathForDirectoriesInDomains(NSDocumentDirectory

问题 To be clear, my question is not asking how to display a PDF in a UIWebview. I want to check if the user has navigated to a PDF (.pdf) document from some website or link. That way I can show more options to the user, like saving the PDF or printing it. What's the best way to check if the UIWebView's content is a PDF? 回答1: You can check the MIME type too, for a slightly longer journey: @property (nonatomic, strong) NSString *mime; - (void)connection:(NSURLConnection *)connection

问题 We bundle a lot of fonts with our iOS app, and we put them all in UIAppFonts for faster loading. (We're using them inside UIWebView and it's much faster than using loading files with @font-face ). However this lead me to occasionally get this kind of warning: Mar 13 23:07:16 iPad afcd[2582] <Error>: Max open files: 78 Mar 13 23:07:17 iPad mobile_house_arrest[2584] <Error>: Max open files: 78 Mar 13 23:07:17 iPad mobile_house_arrest[2586] <Error>: Max open files: 78 Mar 13 23:07:17 iPad mobile

问题 Specifically -- how do you get all the assets to load from their respective directories (images/, css/, js/) without changing the content of the original HTML (removing directories)? I am using this code to load index.html into the UIWebview: NSURL *url = [[NSBundle mainBundle] URLForResource:@"index" withExtension:@"html"]; NSString *html = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil]; NSString *path = [[NSBundle mainBundle] bundlePath]; NSURL *baseURL =
