uiactivity

I have jpg files saved in the Documents directory that can be shared from a standard UIActivityViewController. All activity items (including Save Image) work as expected, but when Save Image is tapped, the following error shows in the console, despite the fact that the jpg does actually get saved to the camera roll. Is this a bug in iOS, or do I have to somehow specify that my file is a jpg (and not a video) in the file URL? 2015-07-29 06:46:58.317 AppName[4658:893408] Video /var/mobile/Containers/Data/Application/A63DF08E-21D0-435D-A0D7-84D73D632FC9/Documents/ImageStore/805/23.jpg cannot be

How do I combine a UIActivityViewController and a UIDocumentInteractionController? The Mail app and the Tumblr app seem to compine a UIActivityViewController with a UIDocumentInteractionController because their controllers also show the "Open in" buttons besides the UIActivities. How can I accomplish this? Use presentOptionsMenuFromRect:inView:animated: in UIDocumentInteractionController 来源： https://stackoverflow.com/questions/19591028/uiactivityviewcontroller-and-uidocumentinteractioncontroller

I am trying to add a custom UIActivity of type UIActivityCategoryAction to UIActivityController . But in iOS 8, all of them are appearing with a black background. Is there a way to change this? There are 3 things to note here: image background, image opaqueness, image size. iOS 7 Image background : Image background should be transparent. image opaqueness The "visible part" of the icon should be non transparent aka opaque. Note that any color information won't be preserved : image size Because the image won't be scaled by the system if too small/big , you have to provide appropriately sized

I am using UIActivityViewController to share some text and url which works great when sending some text and a url. I currently need to use the completion handler to perform additional actions depending whether the user cancelled the UIActivityViewController or actually sent something. The completion handler ( activityViewController.completionHandler for iOS 7 is deprecated in iOS 8 which is now activityViewController setCompletionWithItemsHandler ) returns a BOOL completed value which correctly returns true when sending with email sms Facebook Twitter however when sending via Airdrop the user

I am using UIActivity in ios7. It is working fine with a few lines of code. Now i want to add instagram share button to it. Is there a way to add custom buttons to the action sheet? This is how i am creating the UIActivityViewController : NSString *textToShare = self.navigationItem.title; NSArray *itemsToShare = @[textToShare, [imagesArray objectAtIndex:afImgViewer.currentImage]]; UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:itemsToShare applicationActivities:nil]; activityVC.excludedActivityTypes = @[UIActivityTypePrint,

When using a customer UIActivity subclass in iOS 6, it's possible to specify a custom view controller that will be displayed when your action is chosen from the initial UIActionViewController's view. You do this by returning a reference to a custom view controller from your UIActivity subclass's activityViewController method. According to the UIActivity class reference : activityViewController The default implementation of this method returns nil . Subclasses that provide additional UI using a view controller can override this method to return that view controller. If this method returns a

I am trying to implement a custom activity to the standard activities (Print, Mail, FaceBook, etc.) but for now only want the standard Print (for AirPrint) and my own custom printing by a direct method. I am obviously missing something fundamental as none of the methods in my custom class ever get called. For now I only have some NSLog statement to figure out the calling sequence, and to get the framework to function. The following is my test code for the custom activity class: // PrintActivity.h #import <UIKit/UIKit.h> @interface PrintActivity : UIActivity @end And the .m #import

I recently started working with UIActivity to share my app to the world, but I have few problems. First, I didn't find how to set the subject of my email. Is there any way? Second, when I set the body text of my email, there is a extra "enter" (first line of the email is blank and my text starts at the second line). Here's the code: NSMutableArray *array = [[NSMutableArray alloc] initWithObjects: @"Test", nil]; UIActivityViewController *activityViewController = [[UIActivityViewController alloc] initWithActivityItems:array applicationActivities:nil]; And in the email, it shows that: " Test "
