我曾尝试使用 MFMailComposeViewController，但是当显示视图时，没有看到取消和发送按钮。VC 为白色。我还尝试更改导航栏的一些色调，但没有任何效果。设备使用 iPhone 8

[mailVC setSubject:@"Looko App!"];
[mailVC setMessageBody:@"Found and sent using Demo App!" isHTML:NO];
[mailVC setToRecipients:@[@"[email protected]"]];
[self presentViewController:mailVC animated:YES completion:nil];
委托回调如下
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
switch (result) {
case MFMailComposeResultSent:
NSLog(@"Email sent");
break;
case MFMailComposeResultSaved:
NSLog(@"Email saved");
break;
case MFMailComposeResultCancelled:
NSLog(@"Email cancelled");
break;
case MFMailComposeResultFailed:
NSLog(@"Email failed");
break;
default:
NSLog(@"Error occured during email creation");
break;
}
[self dismissViewControllerAnimated:YES completion:NULL];
}
在启动 MFMailComposeViewController 之前尝试设置导航栏外观：
[UINavigationBar appearance].tintColor = [UIColor yourColor];
MFMailComposeViewController *mailVC = [[MFMailComposeViewController alloc] init];
