我想从我的应用程序发送电子邮件，但是当我点击发送按钮应用程序崩溃时出现问题，我不知道问题出在哪里，因为我在以前的应用程序中使用了这段代码。
-(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

最佳答案
我得到了完全相同的行为。
我通过从我的应用程序委托(delegate)中删除 UIColor colorWithPatternImage: 代码解决了这个问题。
阻止了应用程序崩溃，希望有帮助
