在 iOS 中如何发短信

从 iOS MFMessageComposeViewController，可以用来发短信。

用法：

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init];
picker.messageComposeDelegate = self;
picker.recipients = [NSArray arrayWithObjects:@"1234", @"2345", nil];
picker.body = yourTextField.text

[self presentModalViewController:picker animated:YES];
[picker release];

#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>

@interface YourClass : UIViewController <MFMessageComposeViewControllerDelegate> 
{
    // ...
