以編程方式發送短信代碼問題

Question

我正在編寫代碼以編程方式發送短信 程序在第二行最後一行崩潰。

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

我想這是肯定地說，它實現

UIViewController <MFMessageComposeViewControllerDelegate> 

在這種情況下，我建議要回http://iphonesdkdev.blogspot.com/2010/04/mfmessagecomposeviewcontroller-sample.html，複製他們的榜樣，並從那裏取得進展。
