ios - 如何在 UIVideoEditorController 的工具栏上添加/修改按钮？

Question

我正在尝试将按钮添加到 UIVideoEditorController 的底部工具栏。这可能吗？我可以修改/添加按钮到这个工具栏吗？

Answer 1

Apple Docs明确提到

Important: The UIVideoEditorController class supports portrait mode only. This class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private; do not modify the view hierarchy. This class does not support modifications to its appearance by use of overlay views.

所以基本上是不可能的。

Answer 2

在这里，我留下了一个可能的解决方案，但请始终牢记 Apple 的警告。在这种情况下，我正在更改工具栏的背景颜色，但它应该适用于您想要的任何修改。

 - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{

    [self changeBakcgroundColorOfView:navigationController.topView withColor:[UIColor redColor]];
}

- (void) changeBakcgroundColorOfView:(UIView *)view withColor:(UIColor*)color{

    for (UIView *subview in view.subviews) {

        if ([NSStringFromClass([subview class]) isEqualToString:@"UIToolbar"]) {

            UIToolbar *toolbar = (UIToolbar *)subview;
            toolbar.backgroundColor = color;
            toolbar.barTintColor = color;
        }

        [self changeBakcgroundColorOfView:subview withColor:color];
    }
}
