Question

我想从我的应用程序发送电子邮件，但当我点击发送按钮应用程序崩溃并且我不知道问题出在哪里时出现问题，因为我在之前的应用程序中使用了此代码。

    -(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
    switch (result) {
        case MFMailComposeResultCancelled:
            NSLog(@"Mail cancelled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Mail Saved");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Mail Sent");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Mail sent failure: %@", [error localizedDescription]);
            break;

        default:
            break;
    }

    [self dismissViewControllerAnimated:YES completion:NULL];
}

-(IBAction)sentFeedback:(id)sender
{
    MFMailComposeViewController *sentFeed = [[MFMailComposeViewController alloc] init];
    [sentFeed setMailComposeDelegate:self];
    if ([MFMailComposeViewController canSendMail]) {
        [sentFeed setToRecipients:[NSArray arrayWithObjects:@"something@test.com", nil]];
        [sentFeed setSubject:@"Test Report Problem"];
        [sentFeed setMessageBody:@"" isHTML:NO];
        [sentFeed setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
        [self presentViewController:sentFeed animated:YES completion:NULL];
    }else{
        UIAlertView *sentError = [[UIAlertView alloc] initWithTitle:@"Error" message:@"An Error has Occured" delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [sentError show];
    }
}

这是一个错误报告。请帮忙

我的行为完全相同。

我通过从我的App Delegate中删除UIColor colorWithPatternImage:代码解决了这个问题。

停止应用程序崩溃，希望有所帮助
