我正在呈现这样的邮件作曲家`

I am presenting the mail composer like this `

action
{
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];
    }

}


void)displayComposerSheet 
{

    AppDelegate *appdelegate=[[UIApplication sharedApplication] delegate];
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;  

    [picker setSubject:@"report"];



    // Set up recipients
    NSArray *toRecipients=[NSArray arrayWithObject:@""]; 
    NSArray *ccRecipients =[[NSArray alloc]init];//= [NSArray arrayWithObjects:@"", @"", nil]; 
    NSArray *bccRecipients=[[NSArray alloc]init];// = [NSArray arrayWithObject:@""];    
    [picker setToRecipients:toRecipients];
    [picker setCcRecipients:ccRecipients];  
    [picker setBccRecipients:bccRecipients];    
    [picker setMessageBody:@"Please send me  now." isHTML:YES];





    [appdelegate.navigationController presentModalViewController:picker animated:YES];
    [appdelegate.navigationController.navigationBar setHidden:NO];
    [picker release];
}

推荐答案

我遇到了同样的问题，它似乎是一个与特定 UIAppearance 自定义相关的错误。当我删除 UISearchBar 背景图片的自定义时，它完全消失。

I had the same issue, and it seems to be a bug that is related to specific UIAppearance customizations. It goes away entirely when I remove my customization of UISearchBar background images.
