openURL的使用方法

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];

其中系统的appString有：

Map http://maps.google.com/maps?q=Shanghai

Email mailto://[email protected]

Tel tel://10086

Msg sms://10086

除此之外，还可以自己定义URL，方法如下：

打 开info.plist，添加一项URL types 展开URL types，再展开Item1，将Item1下的URL identifier修改为URL Scheme 展开URL Scheme，将Item1的内容修改为myapp 其他程序可通过myapp://访问此自定义URL

openURL能帮助你运行Maps，SMS，Browser,Phone甚至其他的应用程序。这是Iphone开发中我经常需要用到的一段代码，它仅仅只有一行而已。

- (IBAction)openMaps {
//打开地图
NSString *addressText = @"beijing";
//@"1 Infinite Loop, Cupertino, CA 95014";
addressText = [addressText stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];
NSString *urlText = [NSString stringWithFormat:@"http://maps.google.com/maps?q=%@", addressText];
NSLog(@"urlText =============== %@", urlText);
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlText]];
}

- (IBAction)openEmail {
//打开mail // Fire off an email to apple support
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]];
}

- (IBAction)openPhone {

//拨打电话
// Call Google 411
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8004664411"]];
}

- (IBAction)openSms {
//打开短信
// Text to Google SMS
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://466453"]];
}

-(IBAction)openBrowser {
//打开浏览器
// Lanuch any iPhone developers fav site
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://itunesconnect.apple.com"]];
}
