UIActionSheetdelegate not getting subviews - ios

Question

In my iOS 8 application I am using UIActionSheet. I tried to change the color of the button title in willPresentActionSheet delegate method, but it is not recognizing buttons as its subview.
I constructed UIActionSheet like this:
UIActionSheet *popup = [[UIActionSheet alloc] initWithTitle:#"Select an Option" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles: nil];
popup.tag = 2;
[popup addButtonWithTitle:#"Add Tag To Chat"];
[popup addButtonWithTitle:#"Remove Tag From Chat"];
[popup addButtonWithTitle:#"Terminate"];
[popup addButtonWithTitle:#"Cancel"];
[popup showInView:self.view];
Delegate is:
- (void)willPresentActionSheet:(UIActionSheet *)actionSheet
{
NSLog(#"%d",[actionSheet.subviews count]);
for (UIView *subview in actionSheet.subviews) {
if ([subview isKindOfClass:[UIButton class]]) {
UIButton *button = (UIButton *)subview;
[button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
}
}
}
Buttons are showing, I can click and action performs. But it says count = 0. Why?

Answer 1

Try this way, changing the UIColor of subviews:
UIActionSheet * action = [[UIActionSheet alloc]
initWithTitle:#"Title"
delegate:self
cancelButtonTitle:#"Cancel"
destructiveButtonTitle:nil
otherButtonTitles:#"",nil];
[[[action valueForKey:#"_buttons"] objectAtIndex:0] setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
I've tried it. It is working...

Answer 2

The delegate methods in which you're trying to check the number of subviews: willPresentActionSheet seems inappropriate.
willPresentActionSheet is called before the action sheet actually gets rendered.
If you check the number of subviews in didlPresentActionSheet, that will be more appropriate.
Hope this helps..
