UISearchBar键盘外观

Question

根据这个问题，我们可以更改iOS Can the alert keyboard be used for any text field on iOS?中任何UITextField的键盘外观

但是UISearchBar怎么样？有没有办法，因为[searchBarInstance setKeyboardAppearance:UIKeyboardAppearanceAlert];不起作用，因为UISearchBar缺少这种方法。

Answer 1

你可以这样做，

for(UIView *subView in searchBar.subviews)
  if([subView isKindOfClass: [UITextField class]])
    [(UITextField *)subView setKeyboardAppearance: UIKeyboardAppearanceAlert];
