Determines whether the given URL can be opened by OpenUrl.

[Foundation.Export("canOpenURL:")]
public virtual bool CanOpenUrl (Foundation.NSUrl url);

abstract member CanOpenUrl : Foundation.NSUrl -> bool
override this.CanOpenUrl : Foundation.NSUrl -> bool

Parameters

url: NSUrl

The URL to probe.

This parameter can be null.

Returns

Boolean

true if there is an application registered to open the URL, false if not.

Attributes: ExportAttribute

Remarks

This function probes whether there is a handler for the provided URL on the system. For example, if you call this function with "tel://555-123-1234" on an iPhone, this will return true, but will return false on an iPod Touch.

This function does not validate the URL, it merely checks whether a handler for this URL has been installed on the system.

If you want to define your own URL handlers, edit your Info.plist file and define a new URL type, you then must update your FinishedLaunching(UIApplication, NSDictionary) method (to handle launching the application if it is not already running) and override the M:UIKit.UIApplicationDelegate.OpenUrl* method to handle the request to open the URL.
