Question

我目前有一个应用程序将状态栏样式设置为浅色内容。

[UIApplication sharedApplication].statusBarStyle = UIStatusBarStyleLightContent;

除了全屏模式窗口外，这可以正常工作。这是创建模态UIViewController的代码：

@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

明信片的视图控制器随后显示为

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

在全屏模式下，statusBarStyle会恢复为黑暗内容。如果我将modalPresentationStyle更改为UIModalPresentationFormSheet，则会保留指定内容。

有没有办法以编程方式设置模态窗口的'statusBarStyle`？或者告诉它继承呈现的UIViewController？或者这是一个错误？（注意，我也尝试过设置我的项目属性而没有成功。）

提前致谢！
