Just display the devices IP address, open a socket for listening in an app running on the iOS device, and implement the http protocol. There are several 3rd party libraries that can do most of the heavy lifting for you: CocoaHTTPServer or iPhoneHTTPServer3, or SimpleWebSocketServer, or MultithreadedHTTPServer3
This loop will remove all gesture recognizers a view has for (UIGestureRecognizer *recognizer in self.view.gestureRecognizers) { [self.view removeGestureRecognizer:recognizer]; }
the thing that saved my life: if (self.view.window != nil) [popoverController presentPopoverFromRect:CGRectMake(44, yCoord, 111, 111) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES]; by adding if condition it doesn´t crash anymore. I don´t really get it because the presentPopoverFromRect function is ALWAYS called. There is no situation where window would be nil but anyway it did the trick. edit: I … Read more
The portrait height is 264 while the landscape height is 352. I know this is a late answer, but I just came across this question myself.
Update: I think there’s an even easier way to do this, depending on your application. Instead of having multiple images, if you simply have one <img> element or Image object (or maybe two, like a ‘this’ image and a ‘next’ image if you need animations or transitions) and simply update the .src, .width, .height and … Read more
An indirect and SDK-safe way is to make a text field a first responder. If the external keyboard is present, the UIKeyboardWillShowNotification local notification shall not be posted. Update: This is no longer true since iOS 9, however you may use the keyboard dimensions to determine if a hardware or software keyboard is involved. See … Read more
Interesting question! I came up with the following solution working for images picked from your photo library (note my code is using ARC): Import AssetsLibrary.framework and ImageIO.framework. Then include the needed classes inside your .h-file: #import <AssetsLibrary/ALAsset.h> #import <AssetsLibrary/ALAssetRepresentation.h> #import <ImageIO/CGImageSource.h> #import <ImageIO/CGImageProperties.h> And put this inside your imagePickerController:didFinishPickingMediaWithInfo: delegate method: ALAssetsLibrary *library = [[ALAssetsLibrary … Read more
I’m a year late, but this is pretty straightforward to do. Have your modal view controller attach a gesture recognizer to the view’s window: UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)]; [recognizer setNumberOfTapsRequired:1]; recognizer.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view [self.view.window addGestureRecognizer:recognizer]; [recognizer release]; The handling code: … Read more
heres the basic idea to get to the annots CGPDFDictionary for each page atleast. after that you should be able to figure it out with help from the PDF spec from Adobe. 1.) get the CGPDFDocumentRef. 2.) get each page. 3.) on each page, use CGPDFDictionaryGetArray(pageDictionary, “Annots”, &outputArray) where pageDictionary is the CGPDFDictionary representing the … Read more
After some (a lot of) digging throughout the web, I found the answer. The access Group that you use when constructing your KeychainItemWrapper class must ALSO be specified in each of your application’s Entitlements.plist file in the “keychain-access-groups” section. It seems almost obvious now that I see “keychain-access-groups“. However, I had no idea to even … Read more
