uinavigationcontroller - iOS8中UIImagePickerController隐藏状态栏问题

Question

我做到了

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

它在 iOS7 中很棒，但 iOS8 在 View 之间导航栏的转换方面遇到了一些问题，并表示:

Finishing up a navigation transition in an unexpected state. Navigation Bar subview tree might get corrupted.

那么，有任何已知的解决方案吗？

Answer 1

试试这个。

确保您有图像选择器的委托(delegate)。

imagePicker.delegate = self

现在定义这个函数

- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
    [viewController prefersStatusBarHidden];
    [viewController performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];
}
