  • [转] ios学习--openURL的使用方法

    openURL的使用方法:
    view plaincopy toclipboardprint?
           [[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];  
    其中系统的appString有:

    1.Map    http://maps.google.com/maps?q=Shanghai  
    2.Email  mailto://myname@google.com  
    3.Tel    tel://10086  
    4.Msg    sms://10086  
    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";
        //@"1Infinite Loop, Cupertino, CA 95014"; 
       addressText =[addressTextstringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]; 
       NSString*urlText = [NSStringstringWithFormat:@"http://maps.google.com/maps?q=%@",addressText]; 
       NSLog(@"urlText=============== %@", urlText);
       [[UIApplicationsharedApplication] 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
        // CallGoogle 411
        [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"tel://8004664411"]];
     } 
     
    - (IBAction)openSms {
        //打开短信
         // Text toGoogle SMS
        [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"sms://466453"]];
    }

    -(IBAction)openBrowser {
        //打开浏览器
        // Lanuch any iPhone developers fav site
         [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"http://itunesconnect.apple.com"]];
     }
    iphone程序内调用谷歌地图

    使用CLLocationManager类,MKMapView。并且实现<MKMapViewDelegate,CLLocationManagerDelegate>
    //初始化CLLocationManager,CLLocationManager获得当前地理坐标
    locmanager=[[CLLocationManager alloc]init];

    [locmanager setDelegate:self];
     //设置精确度
    [locmanager setDesiredAccuracy:kCLLocationAccuracyBest];

    [locmanager startUpdatingLocation];
    执行完以后,会自动调用代理方法:
