uiactivityviewcontroller

问题 I'm trying to use the new iOS6 UIActivityViewController and it works fine except that the Memory Leaks instrument says that the NSArray *execludedActivities is leaking every time I try to show the controller. Note that I tried to use an NSArray called excludedActivities and then set the shareShareController.excludedActivityTypes to be able to set the array to nil later (all that is commented code below) but now I'm setting the property directly and still there is a leak. - (IBAction)share:(id

问题 I have a larger app that should be able to share multiple images. I implemented this using UIActivityViewController and UIActivityItemProvider to have asynchronous usage of the items (so that i only have to prepare one image at a time and not have to fill the memory with all of them at once to share them). I was "inspired" by the Apple Airdrop example: AirdropSample download However when using my app to share e.g. 9 images (to camera Roll == "Save 9 images") only 4 to 7 images end up being in

问题 I use UIActivityViewController to share images and text to Message, Email, Facebook, Twitter etc. Until recently, I thought I could send images of any size (at least up to 5MB). However, I have noticed that I can no longer send images greater than say 2.5MB to Facebook or twitter. E.g., I select an image to share, open the activityViewController and select Facebook. The activityViewController slowly opens the Facebook interface/view (but doesn't show attached image) then closes the Facebook

问题 I'm wondering if there is a good way export or share a file through SwiftUI. There doesn't seem to be a way to wrap a UIActivityViewController and present it directly. I've used the UIViewControllerRepresentable to wrap a UIActivityViewController, and it crashes if I, say, present it in a SwiftUI Modal. I was able to create a generic UIViewController and then from there call a method that presents the UIActivityViewController, but that's a lot of wrapping. And if we want to share from the Mac

问题 I'm trying to present a MFMessageComposeViewController from a UIActivityViewController. However, when I select to share using a Message I see this let activityVC = UIActivityViewController(activityItems: ["text"], applicationActivities: nil) self.presentViewController(activityVC, animated: true, completion: nil) I customized my navigation bar appearance in my AppDelegate UINavigationBar.appearance().barTintColor = UIColor.blackColor() UINavigationBar.appearance().tintColor = UIColor

问题 I am trying to exclude all services from my UIActivityType except for email and text message. I am using the following statement: activityController.excludedActivityTypes = @[UIActivityTypeAddToReadingList,UIActivityTypeAirDrop,UIActivityTypeAssignToContact,UIActivityTypeCopyToPasteboard, UIActivityTypePostToFacebook,UIActivityTypePostToFlickr,UIActivityTypePostToTencentWeibo,UIActivityTypePostToTwitter, UIActivityTypePostToVimeo,UIActivityTypePostToWeibo,UIActivityTypePrint

问题 I have been using the code below to show a UIActivityViewController which worked fine when I was using Xcode 6, Swift 1.2 and iOS 8. However when I updated it shows the UIActivityViewController but it is completely blank without any of the sharing options. Do you have any suggestions? if UIDevice.currentDevice().userInterfaceIdiom == .Pad { let textToShare = textViewOne.text let objectsToShare = [textToShare] let activityVC = UIActivityViewController(activityItems: objectsToShare,

问题 Is it possible to check if the recipient 'declined' or 'accepted' the share? I want to NSLog 'sent' if sent and NSLog 'declined' if declined by the user. 来源： https://stackoverflow.com/questions/23495399/uiactivityviewcontroller-airdrop-check-the-status-when-sent-or-declined

问题 I am working on an app that presents some data in a detailViewController. I have a rightBarButton in the navbar that presents a UIActivityViewController that is filled with my own UIActivity sublclassed items. Most of them work fine as they are just changing a small aspect to the data from the detail view, but I need one of them to open a modalViewController when selected. I keep getting the following warning from the console..... Warning: Attempt to present <UINavigationController:
