iOS中可以使用两种方式发送短信，最简单是使用openURL：
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms://10010"]];//发短信
上面方式无法指定短信内容，iOS4.0新加入了MFMessageComposeViewController和MFMessageComposeViewControllerDelegate，提供了发送短信的接口,可以像发送邮件那样不用跳出程序来发送短信. 介绍可参阅Message UIFramework Reference
MFMessageComposeViewController提供了操作界面使用前必须检查canSendText方法,若返回NO则不应将这个controller展现出来,而应该提示用户不支持发送短信功能.
messageComposeDelegate ：代理，处理发送结果
recipients ：收信人<列表，支持群发>
body ：短信内容
Frameworks中要引入MessageUI.framework
#import <MessageUI/MessageUI.h>
添加协议：<MFMessageComposeViewControllerDelegate>
#import <MessageUI/MessageUI.h>
@interface DemoViewController : UIViewController <MFMessageComposeViewControllerDelegate>
@end
调用MFMessageComposeViewController，同时实现协议MFMessageComposeViewControllerDelegate。
- (void)showMessageView
{
if( [MFMessageComposeViewController canSendText] ){
MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc]init]; //autorelease];
controller.recipients = [NSArray arrayWithObject:@"10010"];
controller.body = @"测试发短信";
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
[[[[controller viewControllers] lastObject] navigationItem] setTitle:@"测试短信"];//修改短信界面标题
}else{
[self alertWithTitle:@"提示信息" msg:@"设备没有短信功能"];
}
}
//MFMessageComposeViewControllerDelegate
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{
[controller dismissModalViewControllerAnimated:NO];//关键的一句 不能为YES
switch ( result ) {
case MessageComposeResultCancelled:
[self alertWithTitle:@"提示信息" msg:@"发送取消"];
break;
case MessageComposeResultFailed:// send failed
[self alertWithTitle:@"提示信息" msg:@"发送成功"];
break;
case MessageComposeResultSent:
[self alertWithTitle:@"提示信息" msg:@"发送失败"];
break;
default:
break;
}
}
- (void) alertWithTitle:(NSString *)title msg:(NSString *)msg {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title
message:msg
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"确定", nil];
[alert show];
}
