iOS 调用系统短信、邮件发送界面

iOS调用系统发送短信、邮件有两种方法：一种是直接跳到系统的发送功能界面，完成后不能返回到当前界面；第二种是弹出发送界面，完了之后还在停留在当前界面。

方法一：调用系统的接口，如打电话、发短信、邮件、浏览器等，以下这些通常在传递的参数前要加前缀，@"tel://",@"sms://",@"mailto://",@"http://"

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://123456"]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://123456"]];

[[UIApplication sharedApplication] openURL:[NSURL
URLWithString:@"mailto://12306@sina.com"]];

[[UIApplication sharedApplication] openURL:[NSURL
URLWithString:@"http://www.hao123.com"]]

方法二：是通过调用弹出系统的发送界面，一般通过模态对象实现。

发送短信示例：

-(void)showMessageView : (NSString *)phone title : (NSString *)title body : (NSString *)body

{

if( [MFMessageComposeViewController canSendText] )

{

MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];

controller.recipients = [NSArray arrayWithObject:phone];

controller.body = body;

controller.messageComposeDelegate = self;

[self presentModalViewController:controller animated:YES];

[[[[controller viewControllers] lastObject] navigationItem] setTitle:title];//修改短信界面标题

}

else

{

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"

message:@"该设备不支持短信功能"

delegate:nil

cancelButtonTitle:@"确定"

otherButtonTitles:nil, nil];

[alert show];

}

}

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result

{

[self dismissModalViewControllerAnimated:YES];

switch (result) {

case MessageComposeResultCancelled:

{

//click cancel button

}

break;

case MessageComposeResultFailed:// send failed

break;

case MessageComposeResultSent:

{

//do something

}

break;

default:

break;

}

}

发送邮件示则使用 MFMailComposeViewController，具体的google下
