Opening a File Dialog Box when button is tapped in iphone
button, dialog, file, ios, iphone
Solution
iOS doesn't have a concept of browsing arbitrary local files.
It does have the ability to browse for images from the photo library — for that you can use `UIImagePickerController`.
Other than photos, the only files you can even open are ones that are inside your own sandbox folder (i.e. ones that you've put there yourself). There isn't a built in view controller that will display them — you'd have to write your own that will read the list of files using something like `NSFileManager contentsOfDirectoryAtPath:error:`, and display them in an appropriate UI.
