StatusBarStyle適用於全屏UIViewController

我目前有一個應用程序將狀態欄樣式設置爲淺色內容。StatusBarStyle適用於全屏UIViewController

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

這個按預期工作，除了全屏模式窗口。下面是創建模態的UIViewController代碼：然後

@implementation PostCard 
- (id)initWithToRecipients:(NSArray *)toRecipients subject:(NSString *)subject message:(NSString *)message isHTML:(BOOL)isHTML 
{ 
    if ([MFMailComposeViewController canSendMail] && (self = [super init])) 
    { 
     self.viewController = [MFMailComposeViewController new]; 
     self.viewController.mailComposeDelegate = self; 

     [_viewController setToRecipients:toRecipients]; 
     [_viewController setSubject:subject]; 
     [_viewController setMessageBody:message isHTML:isHTML]; 

     self.viewController.modalPresentationStyle = UIModalPresentationFullScreen; 
     self.viewController.modalTransitionStyle = UIModalTransitionStyleCoverVertical; 
    } else { 
     NSLog(@"Cannont send mail from current device."); 
    } 

    return self; 
} 
... 
@end

明信片的視圖控制器是作爲

[myOtherViewController presentViewController:myPostCard.viewController animated:YES completion:nil];

在全屏模式下，statusBarStyle恢復到暗的內容。如果我將modalPresentationStyle更改爲UIModalPresentationFormSheet，則會保留燈光內容。

有沒有辦法編程設置模式窗口的'statusBarStyle`？或者告訴它從呈現的UIViewController繼承？或者這是一個錯誤？（請注意，我也嘗試設置我的項目屬性，但沒有成功。）

在此先感謝！
