iphoneでのメール

Question

私はiphoneを初めて使っています。私は電子メール機能を実装しようとしています。連絡先を追加する必要があります。連絡先はボタンのクリックイベントに表示されます。連絡先のリストの下で、私は連絡先を選択し、アドレスのテキストフィールドに配置されます。これどうやってするの？

サンプルコードを送信できますか？

ありがとうございます。

使用これは間違いなく動作します。このコードは、

-(IBAction)send{ 
[self callMailComposer]; 
} 

-(void)callMailComposer{ 
Class mailClass = (NSClassFromString(@"MFMailComposeViewController")); 
if (mailClass != nil) 
{ 
    // We must always check whether the current device is configured for  sending emails 
    if ([mailClass canSendMail]) 
     [self displayComposerSheet]; 
    else 
     [self launchMailAppOnDevice]; 
} 

else 
{ 
    [self launchMailAppOnDevice]; 
} 
}
