问题
If a UIAlertView contains a certain amount of text, the text display is automatically changed to have scrollbars. I would like this text to be centre-aligned.
Searching around for the solution provides this SO response. However, this does not work on a UIAlertView that contains scrollbars.
How do I align the text in such an alert?

My suggestion would be to not do this. It could break with any iOS update if Apple changes the way that UIAlertView is structured. That being said, you can do this:
for(id subview in alertView.subviews) {
if([subview isKindOfClass:[UITextView class]]) {
[(UITextView *)subview setTextAlignment:NSTextAlignmentCenter];
}
}
