Apple's documentation for UIDocumentInteractionController presentOpenInMenuFromBarButtonItem:animated: method states that "If there are no registered apps that support opening the document, the document interaction controller does not display a menu." In my app I want to display a button if and only if there is an app on the device that will open it. (I only want the button to pop up a menu to open a file; I don't want QuickLook, Copy or Print). As things stand, if the button is there, but no apps are registered that can open the relevant file, the user gets the unsatisfactory experience of a

Hi i have managed to open .xls files form mail app by adding document type to the project build and set the Types field to "com.microsoft.excel.xls" (see screen shot). I want to do the same with xlsx files but can't do it. I tried to add "com.microsoft.excel.xlsx" but it didn't work I solved that by defining custom UTI as follows. Try to add these definitions into your info.plist. It works as expected. <key>UTExportedTypeDeclarations</key> <array> <dict> <key>UTTypeDescription</key> <string>XLSX input table document</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename

Can anyone explain to me the difference between Document Types, Exported UTIs and Imported UTIs in Xcode 5.1? I want to be able to have my app automatically detect file type based on file extension. Which of these three would I need to implement in order to do that? aldoram5 You add a Document Type to register that your app can open that Document Type, this is simple when you select a known file type , but if the file type is not known, you must also define it in Imported UTIs .

I know this is possible and is something many big apps do, but I can't figure out among UTIs, extensions, UIActivityTypes, etc. which spell I need to use for this in particular.
