程序外调用系统发短信
这个方法其实很简单，直接调用openURL即可：
[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms://13888888888"]];
程序内调用系统发短信
1）导入MessageUI.framework，并引入头文件：
#import <MessageUI/MessageUI.h>
2）实现代理方法MFMessageComposeViewControllerDelegate
-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{[self dismissViewControllerAnimated:YES completion:nil];switch (result) {case MessageComposeResultSent://信息传送成功break;case MessageComposeResultFailed://信息传送失败break;case MessageComposeResultCancelled://信息被用户取消传送break;default:break;}
}
3）发送短信
-(void)showMessageView:(NSArray *)phones title:(NSString *)title body:(NSString *)body
{if( [MFMessageComposeViewController canSendText] ){MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];controller.recipients = phones;controller.navigationBar.tintColor = [UIColor redColor];controller.body = body;controller.messageComposeDelegate = self;[self presentViewController:controller animated:YES completion:nil];[[[[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:nilcancelButtonTitle:@"确定"otherButtonTitles:nil, nil];[alert show];}
}
参数phones：发短信的手机号码的数组，数组中是一个即单发,多个即群发。
4）调用发短信的方法
[self showMessageView:[NSArray arrayWithObjects:@"13888888888",@"13999999999", nil] title:@"test" body:@"你是土豪么，么么哒"];
