UIStackView not reversed when viewDidLoad in RTL language-CodePudding

I have a UIStackView in Storyboard with structure as below and want to scroll it to a specific button in viewDidLoad.

This is how I'm scrolling it.

[self.scrollView scrollRectToVisible:button.frame animated:YES];

The problem is, when setting system language to a RTL language (such as Arabic), the direction of UIStackView and button.frame are still left to right in viewDidLoad, so the scroll position is incorrect.

What should I do to fix this?

CodePudding user response：

As you have seen, frame setup is not completed in viewDidLoad.

Move that code to viewDidAppear:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    [self.scrollView scrollRectToVisible:button.frame animated:YES];
}
