iphone調用系統電話、瀏覽器、地圖、郵件等

openURL的使用方法：
view plaincopy toclipboardprint?
       [[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];  
其中系統的appString有：
view plaincopy toclipboardprint?
1.Map    http://maps.google.com/maps?q=Shanghai  
2.Email  mailto://[email protected]  
3.Tel    tel://10086  
4.Msg    sms://10086  
openURL能幫助你運行Maps，SMS，Browser,Phone甚至其他的應用程序。這是Iphone開發中我經常需要用到的一段代碼，它僅僅只有一行而已。
- (IBAction)openMaps {
    //打開地圖 
   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 {
     //打開mail // Fire off an email to apple support
      [[UIApplication sharedApplication]openURL:[NSURL   URLWithString:@"mailto://[email protected]"]];
 } 
 
- (IBAction)openPhone {
  
    //撥打電話
    // CallGoogle 411
    [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"tel://8004664411"]];
 } 
 
- (IBAction)openSms {
    //打開短信
     // Text toGoogle SMS
    [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"sms://466453"]];
}

-(IBAction)openBrowser {
    //打開瀏覽器
    // Lanuch any iPhone developers fav site
     [[UIApplication sharedApplication] openURL:[NSURLURLWithString:@"http://itunesconnect.apple.com"]];
