发送短信，发邮件，打电话代码实现
基础代码：
    + (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;   
    }


打电话：
+ (void) makeCall:(NSString *)phoneNumber
{
    if ([DeviceDetection isIPodTouch]){
        [UIUtils alert:kCallNotSupportOnIPod];
        return;
    }
    
    NSString* numberAfterClear = [UIUtils cleanPhoneNumber:phoneNumber];    
    
    NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"tel:%@", numberAfterClear]];
    NSLog(@"make call, URL=%@", phoneNumberURL);
    
    [[UIApplication sharedApplication] openURL:phoneNumberURL];    
}


发短信：
    + (void) sendSms:(NSString *)phoneNumber
    {
        if ([DeviceDetection isIPodTouch]){
            [UIUtils alert:kSmsNotSupportOnIPod];
            return;
        }
       
        NSString* numberAfterClear = [UIUtils cleanPhoneNumber:phoneNumber];
       
        NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"sms:%@", numberAfterClear]];
        NSLog(@"send sms, URL=%@", phoneNumberURL);
        [[UIApplication sharedApplication] openURL:phoneNumberURL];   
    }


发邮件：
    + (void) sendEmail:(NSString *)phoneNumber
    {
        NSURL *phoneNumberURL = [NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@", phoneNumber]];
        NSLog(@"send sms, URL=%@", phoneNumberURL);
        [[UIApplication sharedApplication] openURL:phoneNumberURL];   
    }

    + (void) sendEmail:(NSString *)to cc:(NSString*)cc subject:(NSString*)subject body:(NSString*)body
    {
        NSString* str = [NSString stringWithFormat:@"mailto:%@?cc=%@&subject=%@&body=%@",
                         to, cc, subject, body];

        str = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
       
        [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
       
    }
