copied!<p>It was my fault; finally I could solve the problem.</p> <p>The mistake was to use "self.view" and passe it as a parameter for the function "presentOpenInMenuFromRect"</p> <p>[docController presentOpenInMenuFromRect:CGRectZero inView:view animated:YES]</p> <p>However, this"view" (self.view) was not be the suitable one to handle the touch events; this mistake could be noticed thanks to the following warning, which was shown in the Xcode console:</p> <pre><code>2011-08-17 18:12:56.389 MyApplication[287:707] Presenting action sheet clipped by its superview. Some controls might not respond to touches. On iPhone try -[UIActionSheet showFromTabBar:] or -[UIActionSheet showFromToolbar:] instead of -[UIActionSheet showInView:]. </code></pre> <p>This message has given to me the clue and I have modified the code in the following way:</p> <p>The new and right code is:</p> <pre><code>- (void) saveFile:(UIWebView*)webView { NSString* fileName = [[NSFileManager defaultManager] displayNameAtPath:webView.request.URL.absoluteString]; #if DEBUG NSLog(@"<%p %@: %s line:%d> File name:%@", self, [[NSString stringWithUTF8String:__FILE__] lastPathComponent], __PRETTY_FUNCTION__, __LINE__, fileName); #endif NSURL* fileurl = [NSURL URLWithString:webView.request.URL.absoluteString]; NSData* data = [NSData dataWithContentsOfURL:fileurl]; NSArray* paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString* docsDirectory = [paths objectAtIndex:0]; NSString* filePath = [docsDirectory stringByAppendingPathComponent:fileName]; [data writeToFile:filePath atomically:YES]; NSURL* url = [NSURL fileURLWithPath:filePath]; //UIDocInteractionController API gets the list of devices that support the file type docController = [UIDocumentInteractionController interactionControllerWithURL:url]; [docController retain]; //Very important, if "retain" is not called, the application crashes //Present a drop down list of the apps that support the file type, //clicking on an item in the list will open that app while passing in the file. BOOL isValid = [docController presentOpenInMenuFromRect:CGRectZero inView:webView animated:YES]; //Using "webView" instead of "self.view" if (!isValid) { [self showAlertSaveFileError:fileName]; //Shows an alert message } } </code></pre> <p>That is, passing to method "presentOpenInMenuFromRect: inView: animated:" the view "webView" (which is a UIWebView), instead of "self.view".</p>
