IPhone sending SMS implementation

We know that we can use such code in iphone Send text messages in ：

[[UIApplication sharedApplication] openURL:@"sms:12345678"];

But this method can not specify the content of SMS . Then we can use MessageUI frame .

First import in the program MessageUI.framework.import The header file ：#import "DeviceDetection.h"

Then use the following statement in the code to call the SMS sending window , And specify the number and SMS content ：

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
controller.body = @"zc";
controller.recipients = [NSArray arrayWithObjects:@"106295598", nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];

At the same time, the protocol MFMessageComposeViewControllerDelegate, In the protocol method messageComposeViewController:didFinishWithResult:

switch (result) {
    case MessageComposeResultCancelled:
        NSLog(@"Cancelled");
        break;
    case MessageComposeResultFailed:
        [self alert:@" Error sending SMS ！"];
        break;
    case MessageComposeResultSent:
        break;
    default:
        break;
}
[self dismissModalViewControllerAnimated:YES];
