ios - UIActivityViewController with NSURL to audio file only shows airdrop -

I try to use UIActivityViewController to share an audio file (.aac) I am here. This is a temporary file that I have written in the sandboxed document directory.

I pass NS URL to initWithActivityItem: method.

   [AUDIODETA instrument file: [urlToAudioFile path] OPTION: NSDTVViewingPiloting error: & amp; Error]; UIActivityViewController * Activity = [[UIActivityViewController alloc] initWithActivityItems: @ [urlToAudioFile] Application Display: Zero]; [Self.view.window.rootViewController presentViewController: Activity Animated: Yes Completed: ^ {...}];    When I press the share button, it takes a few seconds and activity sheet is the only option which is the airdrope. 
  How can I show other options like email or iMessage? Is there a call back method, so that when I finish the "sharing" I can decide to remove the temporary file again? 
  Is there any way to add any audio file without first typing it on disk? Can not I just pass the  NSData  object?   
 
  If you try to share the actual file, you should see the  UIDocumentInteractionController  Need to use, it is designed to share  entire  files.  UIActivityViewController  is for text and probably has an image 
  If you just need to give message to your file instead of just opening another app, then custom  UIActivity  mfmailcomposeviewcontroller  and  MFMessageComposeViewController  
  for the code> for  UIDocumentInteractionController  and other mail and for other messages (apple Developer):

firebird2.5 - What is the use of firebird.msg in firebird database -



    I'm thinking of using Firebird with my application. I would like to know that the  firebird.msg  is used for the file. Is it an optional or compulsory file to include in your app installer package?       firebird.msg  contains firebird's actual error messages when an error occurs , Firebird only sends the error code and message parameters. The client library then sees the actual error message text in this file.   Without the presence of this file (for firebird 2.5 and earlier its in a folder for  fbclient.dll  (or similar libraries), Firebird 3 and later the same folder In) errormessage will only report that it can not get the  firebird.msg  and error number.   So you do not really need it, but if you need firebird clients or embedded libraries or want and if you want or want a meaningful error message from the firebird, then you should include it.

wordpress widget -



    I am writing a plugin for WordPress and use a table layout in the widget wrapper to display rankings and game schedules.

Due to interchangeable themes in WordPress, I do not know how many widgets will be in WordPress.  and examples of my current theme, based on the available width, I want to display more or fewer columns to fill the row. My idea is to first set the width of the table in the inner width of the wrapping divis, that I can do this with something like    $ ('# objects'). Width ($ ('# Object') .Parent (.) Width ()); Second, it is my goal that to display some columns per line, depending on the width of the row   My questions:    Is my planned way of accomplishing this by sending the width of the table as the parameter of the javasc
