iOS UiWebView “Frame load interrupted”

由 匆匆过客 提交于 2019-12-01 14:42:08
I have a UiWebView that is pointing to an external site that has a session expiration of 30 minutes of inactivity. In my app, I have a custom login page embedded in the application because I can't use one from the remote site. This login page is: file://index.html When the user puts the app into the background, I want to automatically reload my login page if the application stays in the background for more than 20 minutes (I know this isn't ideal, but forced to do this because of the business requirements). My code to do this is fairly simple: static NSDate *lastActivity = nil; - (void

(lots of) UIWebView memory leaks

由 余生长醉 提交于 2019-12-01 14:31:00
I've seen from other posts that there are memory leaking issues with UIWebView. However, with the amount of objects that I have leaking, I have to wonder if I'm doing something wrong. 'Leaks' reports about 60 leaks for opening a UIWebView, loading a page and closing (it's the Facebook login page). I've check the stack trace for every one of these objects, and they never touch my code. They're all either in a separate thread (I only use the main thread), or go from 'main' to a bunch of internal methods that are greyed out. Is this expected from UIWebView? I'm running the latest firmware, and I

Why PDF not opening in iFrame in Chrome when switched to Mobile Device Mode

由 孤人 提交于 2019-12-01 13:45:34
This shows the pdf when we open it in browser. <html> <head> </head> <body> <iframe src="https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/44678.pdf" width="100%" height="100%" > </iframe> </body> </html> But when I switch it to mobile view, it DOESNT work. Steps: Open Chrome Inspect Window. Click "Toggle Device Toolbar" icon on the top menu on inspect window toolbar. Now we can still see the pdf in mobile view. Once we refresh it, we can NO LONGER SEE pdf. Why ? I need to iframe the pdf and show it in mobile app in web view. Is it possible or not ? 来源： https:/

Problem calling a Local HTML File from XCode

由 南楼画角 提交于 2019-12-01 12:16:39
Here's my WebView Code: [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath: [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]isDirectory:NO]]]; Here's my Error: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:isDirectory:]: nil string parameter' Can anyone help? It's saying nil string but the NSURL string is index.html My only thought is that perhaps the index file isn't stored correctly. It's in the project directory - the same folder as the XCode project file xcodeproj and the info.plist

load local HTML file when link is clicked in WebView

由 徘徊边缘 提交于 2019-12-01 12:08:28
I have a WebView that loads a local HTML file like this: [webView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"test1" ofType:@"html"]isDirectory:NO]]]; What I want is to click a link in the test1 local HTML file and then for the webView to load the test2 local HTML file. How can I do this? Like in a regular webpage. Let the link in test 1 point to test2. Instead of loading a request, use the - (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL method. Create an NSString from the local HTML file like this: NSError *error
