MFMailComposerViewController가 전자 메일을 보내지 않음

Question

전자 메일 및 SMS 기능을 구현하는 을 구현했지만 이메일과 SMS를 보낼 수 없습니다. 응용 프로그램이 충돌합니다

잘. . . 는 내가 시뮬레이터 에서 실행하고 있지만, 다음과 같이

내 인터페이스 코드가 충돌 안 년대 AlertView 를 표시해야합니다 : - 다음과 같이

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

@interface MessagingVC :UIViewController<MFMessageComposeViewControllerDelegate,MFMailComposeViewControllerDelegate,UITextFieldDelegate,UITextViewDelegate> 
- (IBAction)sendEmail:(id)sender; 
- (IBAction)sendSMS:(id)sender; 
@property (retain, nonatomic) IBOutlet UITextField *EmailToTxtField; 
@property (retain, nonatomic) IBOutlet UITextField *PhoneToTxtField; 
@property (retain, nonatomic) IBOutlet UITextView *massageBodyTxtView; 
@property (retain, nonatomic) NSMutableArray *toRecipentsEmail; 
@property (retain, nonatomic) NSMutableArray *toRecipentsPhone; 
@property (retain, nonatomic) MFMessageComposeViewController *MessageCompVC; 
@property (retain, nonatomic) MFMailComposeViewController *MailCompVC; 
@end 

내 구현 코드는 다음과 같습니다 - 내가 sendEmail 클릭

#import "MessagingVC.h" 

@interface MessagingVC() 

@end 

@implementation MessagingVC

하지만, 톤 내가 무슨 일을하고 있는가 말해주십시오이 출력

와 응용 프로그램이 충돌? 나는이 문제이지만, 코드, 라인에서 그냥 배열의 오토 릴리즈 사본을 반환합니다

toRecipentsEmail = [NSMutableArray arrayWithArray:[textField.text componentsSeparatedByString:@","]]; 

그래서 그냥 시도 여부를 확실히 모르겠어요

Answer 1

self.toRecipentsEmail = [NSMutableArray arrayWithArray:[textField.text componentsSeparatedByString:@","]] ; 

toRecipentsEmail 속성을 합성 했으므로이 작업을 수행하면 배열 복사본이 유지됩니다.
