Hello bro, in IOS 18 our team find issue ,We created a button like this: UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; button.titleLabel.font = [UIFont fontWithName:paramFontName size: fontSize]; Please tell me whether we need to set button frame before we call button.titleLabe?

There is no such requirement, and the exception is being thrown from within an internal method that is trying to create the label for you. But I cannot reproduce your issue internally, and it is unclear exactly what is causing the exception (the exact exception message would be useful to know).
