iOS开发：调用打电话，发短信，打开网址

• 调用 自带mail

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

• 调用 电话phone

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

• 调用 SMS

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

• 调用自带 浏览器 safari

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

• 调用phone可以传递号码，调用SMS 只能设定号码，不能初始化SMS内容。

• 若需要传递内容可以做如下操作：
  加入：MessageUI.framework

#import <MessageUI/MFMessageComposeViewController.h>
实现代理：MFMessageComposeViewControllerDelegate
调用sendSMS函数
//内容，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];
 
    }   
 
}

 
// 处理发送完的响应结果
- (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");
}
 

• 发送邮件的为：
  导入#import <MessageUI/MFMailComposeViewController.h>
  实现代理：MFMailComposeViewControllerDelegate

//发送邮件
-(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];
 
    }    
}

//邮件完成处理
-(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");  
 
}
