Iphone的发送短信邮件打电话代码示例

Map    http://maps.google.com/maps?q=Shanghai
Email  mailto://myname@google.com
Tel    tel://10086
Msg    sms://10086
openURL的使用方法： 
CODE:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:appString]];
 
除此之外，还可以自己定义URL，方法如下：
CODE:
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
+ (void)alert:(NSString *)msg 
{ 
    UIAlertView *alertView = [[[UIAlertView alloc] initWithTitle:msg message:@"" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] autorelease]; 
    [alertView showWithBackground]; 
} 
  
+ (NSString*) cleanPhoneNumber:(NSString*)phoneNumber 
{ 
    NSString* number = [NSString stringWithString:phoneNumber]; 
    NSString* number1 = [[[number stringByReplacingOccurrencesOfString:@" " withString:@""] 
                          //                        stringByReplacingOccurrencesOfString:@"-" withString:@""] 
                          stringByReplacingOccurrencesOfString:@"(" withString:@""]  
                         stringByReplacingOccurrencesOfString:@")" withString:@""]; 
      
    return number1;     
} 
  
+ (void) makeCall:(NSString *)phoneNumber 
{ 
    NSString* numberAfterClear = [self cleanPhoneNumber:phoneNumber];     
      
    NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", numberAfterClear]]; 
    NSLog(@"make call, URL=%@", phoneNumberURL); 
      
    [[UIApplication sharedApplication] openURL:phoneNumberURL];     
} 
  
拔打前会有提示，并且拔打结束后返回到自己的应用程序
[[UIApplicationsharedApplication] openURL:[NSURLURLWithString:@"telprompt://10086"]];
 
直接拔打，不会提示，拔打结束后停留在电话应用上
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];

{ 
      
    NSString* numberAfterClear = [self cleanPhoneNumber:phoneNumber];

    NSLog(@"send sms, URL=%@", phoneNumberURL); 
    [[UIApplication sharedApplication] openURL:phoneNumberURL];     
}
