以编程方式发送短信代码问题

Question

我正在编写代码以编程方式发送短信 程序在第二行最后一行崩溃。

MFMessageComposeViewController *picker = [[MFMessageComposeViewController alloc] init]; 
picker.messageComposeDelegate = self; 
picker.recipients = [NSArray arrayWithObject:@"123456789"]; // your recipient number or self for testing 

picker.body = @"test from OS4"; 
[self presentModalViewController:picker animated:YES]; 
[picker release]; 

Answer 1

我想这是肯定地说，它实现

UIViewController <MFMessageComposeViewControllerDelegate> 

在这种情况下，我建议要回http://iphonesdkdev.blogspot.com/2010/04/mfmessagecomposeviewcontroller-sample.html，复制他们的榜样，并从那里取得进展。
