Reference to this application (SharedApplication).

Attributes
ExportAttribute ObsoletedAttribute UnavailableAttribute

Remarks

When overridden, the application should open the url and return a boolean indicating whether the retrieval was successful.

If the origin of the request was another application, the methods WillFinishLaunching(UIApplication, NSDictionary) and FinishedLaunching(IUIApplicationDelegate, UIApplication, NSDictionary) will be called prior to this method and can be used to prevent this method from being called.

If the url originated in a UIDocumentInteractionController, the annotation may contain additional information specified by the sourceApplication. Files sent via UIDocumentInteractionController will be in the application's Documents/Inbox directory. Applications do not have write access to this directory, so if the file needs to be modified, it must be moved to a write-enabled directory. If the file is protected and the user locks the device, it will be inaccessible. (see ProtectedDataDidBecomeAvailable(UIApplication) and ProtectedDataAvailable).

Applications that wish to be activated using M:UIKit.UIApplicationDelegate.OpenURL* must set the CFBundleURLTypes in their Info.plist file, as a child of the <plist><dict> element. The following example shows how a viewer to handle the URL scheme foo://host:port/path?query might be declared:

<key>CFBundleURLTypes</key>
<array>
<dict>
<key>CFBundleURLName</key>
<string>com.xamarin.MyUniqueIdentifier</string>
<key>CFBundleURLSchemes</key>
<array>
<string>foo</string>
</array>
<key>CFBundleURLTypes</key>
<string>Viewer</string>
</dict>
</array>
