• 調用 自帶mail

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@hzlzh.com"]];

• 調用 電話phone

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8008808888"]];

• 調用 SMS

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://800888"]];

• 調用自帶 瀏覽器 safari

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.hzlzh.com"]];

• 調用phone可以傳遞號碼，調用SMS 只能設定號碼，不能初始化SMS內容。

• 若需要傳遞內容可以做如下操作：
  加入：MessageUI.framework

#import <MessageUI/MFMessageComposeViewController.h>
實現代理：MFMessageComposeViewControllerDelegate
調用sendSMS函數
//內容，收件人列表
- (void)sendSMS:(NSString *)bodyOfMessage recipientList:(NSArray *)recipients
{
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
 
    if([MFMessageComposeViewController canSendText])
 
    {
 
        controller.body = bodyOfMessage;   
 
        controller.recipients = recipients;
 
        controller.messageComposeDelegate = self;
 
        [self presentModalViewController:controller animated:YES];
 
    }   
 
}

 
// 處理發送完的響應結果
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [self dismissModalViewControllerAnimated:YES];
    
    if (result == MessageComposeResultCancelled)
        NSLog(@"Message cancelled");
    else if (result == MessageComposeResultSent)
        NSLog(@"Message sent");
    else
        NSLog(@"Message failed");
}
 

• 發送郵件的為：
  導入#import <MessageUI/MFMailComposeViewController.h>
  實現代理：MFMailComposeViewControllerDelegate

//發送郵件
-(void)sendMail:(NSString *)subject content:(NSString *)content{
 
    MFMailComposeViewController *controller = [[[MFMailComposeViewController alloc] init] autorelease];
 
    if([MFMailComposeViewController canSendMail])
 
    {
 
        [controller setSubject:subject];
 
        [controller setMessageBody:content isHTML:NO];
 
        controller.mailComposeDelegate = self;
 
        [self presentModalViewController:controller animated:YES];
 
    }    
}

//郵件完成處理
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error{
 
    [self dismissModalViewControllerAnimated:YES];
 
    if (result == MessageComposeResultCancelled)
        NSLog(@"Message cancelled");
    else if (result == MessageComposeResultSent)
        NSLog(@"Message sent"); 
    else 
        NSLog(@"Message failed");  
 
}
