问题 I am an iOS developer and I am currently using SLComposeViewController to share a post on Facebook/Twitter. My issue is that I have to post multiple images in a single post. I have done this as follows: SLComposeViewController* mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; [mySLComposerSheet setInitialText:textTobeShared]; mySLComposerSheet addURL:[NSURL URLWithString:@"http://click-labs.com/"]]; for(int count=0;count<imageArray.count

The buttons not only have an action to open the app they represent, but they can be dragged if tapped and held. There is another scrollview below the scrollview in question that accepts the dragging of the buttons. Everything has and is working as expected pre iOS 7. On an iOS 7 device, the button taps are being registered as soon as the scrollview

问题 Is there anyway to position UITabBar badge? It looks little displaced in iOS7. In iOS7, it is displaced towards next tab bar item. I have used a custom tab bar item. UINavigationController *navController = [self.viewControllers objectAtIndex: 0]; UIViewController *viewController = [navController.viewControllers objectAtIndex:0]; CustomTabBarItem *tabBarItem = [[CustomTabBarItem alloc] initWithTitle:EMPTY_STRING image: nil tag:2]; [tabBarItem setImageInsets:UIEdgeInsetsMake(-14.5, 0, 14.5, 0)]

It is working well in iOS 6 but the app crashes for iOS 7 and only for iPhone.

问题 I am using the following code to get the distance between two circular bodies of different radius: distance = b2Distance(body1->GetPosition(), body2->GetPosition()); I have realized that variable distance is storing the distance between the two centers of the bodies, but not the distance between the borders. What I want is distance=0 when the two bodies are touching. How can I do that? I've been trying this code but it fails: b2DistanceInput *distanceInput; distanceInput->transformA = body1-

问题 I have a UIWebView that shows some text, I want to disable zoom/unzoom but I want to detect when users tap on a link. I have tried with disabling MultiTouch but zoom is still working. 回答1: Setting the minimumZoomScale and maximumZoomScale on your webview's UIScrollView to be 1.0 should prevent the webview from zooming. webview.scrollView.maximumZoomScale = 1.0; webview.scrollView.minimumZoomScale = 1.0; 回答2: Try this - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return

问题 I am making a tweak for iOS 7 , in which I want to know about app launch event, and the details of app being launched (name and identifier). So far the only useful framework I have found is SpringBoardServices.framework . The header files which may be/are useful to track app launch event include: SBAppLaunchUtilities.h SBLaunchAppListener.h If I am on right track, can anyone provide me information about their methods usage? There is no relevant information or guide present on iphonedevwiki .
