This document describes several URL schemes that are supported by system apps on iOS and OS X. Native iOS
apps and web apps running in Safari on any platform can use these schemes to integrate with system apps
and provide a more seamless experience for the user. For example, if your iOSappdisplays telephonenumbers,
you could use an appropriate URL to launch the Phone app whenever someone taps one of those numbers.
Similarly, clicking an iTunes link, launches the iTunes appandplays thesong specified in the link. What happens
when a user clicks a link depends on the platform and the installed system apps.
This document describes those schemes that require special attributes or special formatting in order to be
understood by the associated system app. As a result, this document does not describe all URL schemessupported on different Apple platforms.
At a GlanceYou should read this document if you want to launch a system app from your iOS or OS X app or from your
web app running in Safari. This document contains both Cocoa Touch sample codeusing the openURL:
method of the sharedUIApplicationobject to open URLsand HTML samples. For more information on
how to use the openURL:method, seeUIApplication Class Reference .

Themailtoscheme is used to launch the Mail app and open the email compose sheet. When specifying a
mailtoURL, you must provide the target email address. The following examples show strings formatted for
Safari and for native apps.
HTML link:
John Frank
Native app URL string:
mailto:[email protected]
You can also include a subject field, a message, and multiple recipients in the To, Cc, and Bcc fields. (In iOS,
thefromattribute is ignored.) The following example shows a mailtoURL that includes several different
attributes:
mailto:[email protected][email protected]&subject=Greetings%20from%20Cupertino!&body=Wish%20you%20were%20here!
For detailed information on the format of the mailtoscheme, seeRFC 2368.
iOS Note: If the Mail app is not installed, clicking amailtoURL displays an appropriate warning
message to the user.

Note: Phone links are supported on iOS only.
The tel URL scheme is used to launch the Phone app on iOS devices and initiate dialing of the specified phone
number. When a user taps a telephone link in a webpage, iOS displays an alert asking if the user really wants
to dial the phone number and initiates dialing if the user accepts. When a user opens a URL with the tel
scheme in a native app, iOS does not display an alert and initiates dialing without further prompting the user.
However, a native app can be configured to display its own alert.
You can specifyphone links explicitly in both web and native iOS apps using the tel URL scheme. The following
examples show the strings formatted for Safari and for a native app:
HTML link:
1-408-555-5555
Native app URL string:
tel:1-408-555-5555
To prevent users from maliciously redirecting phone calls or changing the behavior of a phone or account, the
Phone app supports most, but not all, of the special characters in the tel scheme. Specifically, if a URL contains
the*or#characters, the Phone app does not attempt to dial the corresponding phone number. If your app
receives URL strings from the user or an unknown source, youshould also make sure that any special characters
that might not be appropriate in a URL are escaped properly. For native apps, use the
stringByAddingPercentEscapesUsingEncoding: method ofNSStringto escape characters, which
returns a properly escaped version of your original string.
In Safari on iOS, telephone number detection is on by default. However, if your webpage contains numbers
that can be interpreted as phone numbers, but are not phone numbers, you can turn off telephone number
detection. You might also turn off telephone number detection to prevent the DOM document from being
modified when parsed by the browser. To turn off telephone number detection in Safari on iOS, use the
format-detectionmeta tag as follows:

Listing 2-1 shows a simple webpage in which automatic telephone number detection is off. When displayed
in Safari on iOS, the408-555-5555telephone number does not appear as a link. However, the1-408-555-5555number does appear as a link because it is in a phone link.
Listing 2-1 Turning telephone number detection off
Telephone Number Detection
A phone number: 1-408-555-5555
Not a phone number: 408-555-5555
iOS Note: If the Phone app is not installed on the iOS device, opening a telURL displays an
appropriate warning message to the user.
For more information about thetelURL scheme, seeRFC 2806andRFC 2396.

ThefacetimeURL scheme is used to launch the FaceTime app and initiate a call to the specified user. You
can use the phone number or email address of a user to initiate the call. When a user taps a FaceTime link in
a webpage, iOS confirms that the user really wants to initiate a FaceTime call before proceeding. When an app
opens a URL with the facetime scheme, iOS opens the FaceTime app and initiate the call without prompting
the user. When opening FaceTime URLs on OS X, the system always prompts the user before initiating a call.
You can specify FaceTime links explicitly in both web and native iOS apps using the facetimeURL scheme.
The following examples show the strings formatted for Safari and for a native app:
HTML link:
Connect using FaceTime
Connect using FaceTime
Native app URL string:
// 14085551234facetime:
facetime://[email protected]
To prevent users from maliciously redirecting calls or changing thebehavior of a phone or account, theFaceTime
app supports most, but not all, of the special characters in the facetime scheme. Specifically, if a URL contains
the * or #characters, the app ignores those characters when they are included after thephone number. If your
app receives URL strings from the user or from an unknown source, use the
stringByAddingPercentEscapesUsingEncoding: methodofNSString to generate a properly escaped
version of the original string before opening the URL.
iOS Note: If the FaceTime app is not installed on the iOS device or OS X computer, opening a
facetimeURL displays an appropriate warning message to the user. Prior to iOS 7, the Phone app
handles FaceTime calls.

Note: SMS text links are supported on iOS only.
Thesmsscheme is used to launch the Messages app. The format for URLs of this type is sms:,
whereis an optional parameter that specifies the target phone number of the SMS message. This
parameter can contain the digits 0 through 9 and the plus (+), hyphen (-), and period (.) characters. The URL
string must not include any message text or other information.
The following examples show strings formatted for Safari and for native apps. HTML links:
Launch Messages App
New SMS Message
Native app URL strings:
sms:
sms:1-408-555-1212

The maps URL scheme is used to show geographical locations and to generate driving directions between two
points. If your app includes address or location information, you can use map links to forward that information
to the Maps app on iOS or OS X.
Unlike some schemes, map URLs do not start with a maps scheme identifier. Instead, map links are specified
as regularhttplinks and are opened either in Safari or the Maps app on the target platform. The following
examples show the strings you would use in Safari and in a native app to show a map of the city of Cupertino,
California in the Maps app.
HTML link:
Cupertino
Native app URL string:
http://maps.apple.com/?q=cupertino
The following examples show the strings you would use to provide driving directions between San Francisco
and Cupertino:
HTML link:
Directions
Native app string:
http://maps.apple.com/?daddr=San+Francisco,+CA&saddr=cupertino

URLs that contain no path parameters or that contain specific map paths are opened in Safari and displayed
there. For example,URLs basedonthepathshttp://maps.apple.com/ , http://maps.apple.com/maps ,
http://maps.apple.com/local , and http://maps.apple.com/mare all opened in Safari. To open a
URL in the Maps app, the path must be of the form http://maps.apple.com/?q.
The rules for creating a valid map link are as follows:
The domain must be maps.apple.com.
The path cannot be/maps/*.
A parameter cannot beq=*if the value is a URL (so KML is not picked up).
The parameters cannot includeview=textordirflg=r.
Table 5-1 lists the supported parameters along with a brief description of each.
Table 5-1 Supported Apple Maps parameters
NotesParameter
The query parameter. This parameter is treated as if it had been typed into the query
box by the user in the Maps app. q=*is not supported
q=
The location part of the query.near=
The latitude and longitude points (in decimal format, comma separated, and in that
order) for the map center point.
ll=
The latitude and longitude points from which a business search should be performed.sll=
The approximate latitude and longitude span.spn=
A custom latitude and longitude span format used by Apple. The value of this parameter
is the latitude and longitude separated by a comma. For example, to specify a latitudinal
span of 20.4 degrees and a longitudinal span of 30.8 degrees, you would use the string
sspn=20.4,30.8.

The iTunes URL scheme is used to link to content on the iTunes Music Store. The iTunes URL format is
complicated to construct, so you create it using an online tool called iTunes Link Maker. The tool allows you
to select a country destination and media type, and then search by song, album, or artist. After you select the
item you want to link to, it generates the corresponding URL.
The following examples show the strings you would use in Safari and in a native iOS app to link to a song on
the iTunes Music Store. The HTML example includes the complete link returned by the iTunes Link Maker tool,
which includes a link to any appropriate artwork for the target link.
HTML link:
Native app URL string:
http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewAlbum?i=156093464&id=156093462&s=143441

The YouTube URL scheme is used to connect to the YouTube website to play the specified video. If your app
links to YouTube content, you can use this scheme to play videos from your app.
Unlike some schemes, YouTubeURLs do notstart with a youtube schemeidentifier. Instead, they arespecified
as regularhttplinks but are targeted at the YouTube server. The following examples show the basic strings
you would use in Safari and in an app to show a YouTube video. In each example, you would need to replace
the VIDEO_IDENTIFIERvalue with the identifier of the video you wanted to display:
HTML links:
Play Video
Play Video
Native app URL strings:
http://www.youtube.com/watch?v=VIDEO_IDENTIFIER
http://www.youtube.com/v/VIDEO_IDENTIFIER
iOS Note: If the YouTube video cannot be viewedon the device, iOSdisplays an appropriate warning
message to the user.
