openURL的使用

查资料的时候无意间发现了一个很好玩的：

代码段：[[UIApplication sharedApplication] openURL:url];

其中系统的url有：

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

2.Email mailto://myname@google.com

3.Tel tel://10086

4.Msg sms://10086

- (IBAction)openMaps {
//打开地图 
NSString*addressText = @"beijing";
//@"1Infinite 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://devprograms@apple.com"]];
} 

- (IBAction)openPhone {

//拨打电话
// Call Google 411
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];
} 

- (IBAction)openSms {
//打开短信
// Text toGoogle SMS
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://10086"]];
}

-(IBAction)openBrowser {
//打开浏览器
// Lanuch any iPhone developers fav site
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://blog.csdn.net/duxinfeng2010"]];
}

自己copy回去玩玩，很有意思的，呵呵
