Question

我正在尝试禁用iOS中的单个viewController的旋转，我已经看到一些问题要求自动旋转但是没有。

我想锁定View B打开的方向。例如：在横向打开，它只能是横向，或以纵向打开，它只能是纵向。同时仍然允许视图A成为它想要的任何方向。

修改 \ n 这就是我称之为视图B

的方式

    [self.mediaFocusController showImageFromURL:url fromView:self.view withThumb:thumbUrl];

这是它进入的方式：

if (self.targetViewController) {
    [self willMoveToParentViewController:self.targetViewController];
    if ([UIView instancesRespondToSelector:@selector(setTintAdjustmentMode:)]) {
        self.targetViewController.view.tintAdjustmentMode = UIViewTintAdjustmentModeDimmed;
        [self.targetViewController.view tintColorDidChange];
    }
    [self.targetViewController addChildViewController:self];
    [self.targetViewController.view addSubview:self.view];

    if (self.snapshotView) {
        [self.targetViewController.view insertSubview:self.snapshotView belowSubview:self.view];
        [self.targetViewController.view insertSubview:self.blurredSnapshotView aboveSubview:self.snapshotView];
    }
}
else {
    // add this view to the main window if no targetViewController was set
    if ([UIView instancesRespondToSelector:@selector(setTintAdjustmentMode:)]) {
        self.keyWindow.tintAdjustmentMode = UIViewTintAdjustmentModeDimmed;
        [self.keyWindow tintColorDidChange];
    }
    [self.keyWindow addSubview:self.view];

    if (self.snapshotView) {
        [self.keyWindow insertSubview:self.snapshotView belowSubview:self.view];
        [self.keyWindow insertSubview:self.blurredSnapshotView aboveSubview:self.snapshotView];
    }
}

我设置了NavigationController，但这个视图不同

尝试此代码（我在https://stackoverflow.com/a/17377221/2040992中找到）：

- (BOOL)shouldAutorotate
{
    id currentViewController = self.topViewController;

    if ([currentViewController isKindOfClass:[DetailViewController class]])
        return NO;

    return YES;
}
