IOS 开发：调用打电话，发短信，打开网址

1、调用 自带mail

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]];

2、调用 电话phone

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

3、调用 SMS

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

4、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”);  

}
