在iOS开发中,经常需要调用其它App,如拨打电话、发送邮件等。UIApplication:openURL:方法是实现这一目的的最简单方法,该方法一般通过提供的url参数的模式来调用不同的App。
通过openURL方法可以调用如下应用:
- 调用谷歌地图(Google Maps)
- 调用邮件客户端(Apple Mail)
- 拨号(Phone Number)
- 调用短信(SMS)
- 调用浏览器(Safari Browser)
- 调用应用商店(AppStore)
调用谷歌地图(Google Maps)
URL模式:http://maps.google.com/maps?q=<strong>${QUERY_STRING}</strong>
代码示例:
NSString* searchQuery =@"1 Infinite Loop, Cupertino, CA 95014";
searchQuery =[addressText stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding];
NSString* urlString =[NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", searchQuery];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlText]];
调用邮件客户端(Apple Mail)
URL模式:mailto://<strong>${EMAIL_ADDRESS}</strong>
代码示例:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@eyecm.com"]];
拨号(Phone Number)
URL模式:tel://<strong>${PHONE_NUMBER}</strong>
代码示例:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];
调用短信(SMS)
URL模式:sms:<strong>${PHONENUMBER_OR_SHORTCODE}</strong>
代码示例:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms:10086"]];
调用浏览器(Safari Browser)
代码示例:
NSURL*url =[NSURL URLWithString:@"http://eyecm.com"];
[[UIApplication sharedApplication] openURL:url];
调用应用商店(AppStore)
URL模式:http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=291586600&mt=8
代码示例:
NSURL*appStoreUrl =[NSURL URLWithString:@"http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=291586600&amp;mt=8"];
[[UIApplication sharedApplication] openURL:appStoreUrl];
