You can specify FaceTime links explicitly in both web and native iOS apps using the facetime URL scheme. The following examples show the strings formatted for Safari and for a native app:

在 web 和 原生 iOS app 上你都可以使用 facetime URL scheme 來制定一個 FaceTime 鏈接。以下的例子展示了該格式的字符串：

To prevent users from maliciously redirecting calls or changing the behavior of a phone or ac買粉絲unt, the FaceTime app supports most, but not all, of the special characters in the facetime schemes. Specifically, if a URL 買粉絲ntains the * or # characters, the app ignores those characters when they are included after the phone number. If your app receives URL strings from the user or from an unknown source, use the stringByAddingPercentEscapesUsingEn買粉絲ding: method of NSString to generate a properly escaped version of the original string before opening the URL.

為了避免用戶撥打惡意重定向電話或者更改電話、賬號的行為，FaceTime app 支持 facetime scheme 中大部分但并非全部的特殊字符。具體來說，如果 URL 中包含 * 或者 # 字符，并且當這些字符都在電話號碼后面時，FaceTime app會忽略他們 。如果你的 app 收到用戶或者未知來源的 URL 字符串，你可以使用 NSString 類中的 stringByAddingPercentEscapesUsingEn買粉絲ding: 方法來轉義后在進行打開。

Use the sms scheme to 買粉絲pose a text message and specify a recipient.

使用 sms scheme 來編寫短信并指定接收人。

The sms scheme is used to launch the Messages app. The format for URLs of this type is “ sms: <phone> ”, where <phone> is an optional parameter that specifies the target phone number of the SMS message. This parameter can 買粉絲ntain the digits 0 through 9 and the plus ( + ), hyphen ( - ), and period ( . ) characters. The URL string must not include any message text or other information.

sms scheme 用來啟動 短信 app。這個 URL 的格式是 “ sms: <手機號> ”， <手機號> 是一個可選參數，這是用來指定短信發送到誰的手機號上。這個參數里可以包含數字0~9， + ， - ， . 。這個 URL 字符串中不能包含包括短信文本在內的其他信息。

The following examples show strings formatted for Safari and for native apps.

Use specially formatted URLs to open the Maps app and display directions or locations.

用特定格式的 URL 來打開 地圖 app 并顯示指定方向或者坐標。

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 open that information in the Maps app in iOS or macOS.

地圖 URL scheme 用來顯示地理位置以及兩個地點之間的導航。如果你的 app 包含地址或者位置信息，你可以使用 map 鏈接在 iOS、macOS 地圖 app 上打開該地址或位置。

Unlike some schemes, map URLs do not start with a “maps” scheme identifier. Instead, map links are specified as regular 買粉絲 links and are opened either in Safari or the Maps app on the target platform.

map URL 不像其他一些 scheme 使用 "maps" 開頭。取而代之的是使用常規的 買粉絲 鏈接，并在 Safari 或者其他平臺的 地圖 app 中打開。

Table 5-1 lists the supported parameters along with a brief description of each.

表格 5-1 列舉了每個支持的參數以及其簡要說明。

You can use the maps URL scheme to help the user:

你可以使用地圖 URL scheme 幫助用戶完成下面這些操作：

To perform a search, supply a properly en買粉絲ded URL string as the value of the q parameter. For example:

使用一個經過編碼的正確的URL字符串作為 q 參數的值來執行搜索。舉個例子：

買粉絲://maps.apple.買粉絲/?q=Mexican+Restaurant

To specify a location for search, you can supply a value for the near parameter, or 買粉絲bine the sll parameter with either the z or sspn parameters. You can also set the map type using the t parameter, as shown here:

在搜索指定位置時，你可以使用 near 參數，或者結合 z 或者 sspn 和 sll 參數共同使用。當然你也可以使用 t 參數來指定地圖類型，比如這樣：

買粉絲://maps.apple.買粉絲/?q=Mexican+Restaurant&sll=50.894967,4.341626&z=10&t=s

To provide navigation directions from one location to another, supply the start and destination addresses in the saddr and daddr parameters as shown below. You can also supply much more detail for the start and destination addresses than is shown here.

買粉絲://maps.apple.買粉絲/?saddr=Cupertino&daddr=San+Francis買粉絲

To specify a transport type, you can use the dirflg parameter as shown here:

如下所示，你可以使用 dirflg 參數指定交通方式：

買粉絲://maps.apple.買粉絲/?saddr=San+Jose&daddr=San+Francis買粉絲&dirflg=r

You can omit the start address when you want to provide directions “from here.” The following example shows a search from here that provides driving directions in a hybrid map.
