ios - 是否可以在不调暗背景的情况下在 iPad 上呈现模态视图 Controller ？

Question

我想展示一个模态视图 Controller ，它不会使背后的内容变暗。只使用标准的 presentViewController。仅仅将 View Controller 的 subview 添加到父 View 会导致问题。

Answer 1

试试这个:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    // remove the dimming view if needed, when this view controller will appear as modal
    id <UIViewControllerTransitionCoordinator> transitionCoordinator = self.transitionCoordinator;
    if (transitionCoordinator.presentationStyle != UIModalPresentationNone) {
        for (UIView *transitionContainerSubview in transitionCoordinator.containerView.subviews) {
            if ([NSStringFromClass([transitionContainerSubview class]) isEqualToString:@"UIDimmingView"]) {
                transitionContainerSubview.hidden = YES;
            }
        }
    }
}
