I am using UISearchBar
in my code. I have imported its delegate in header file and implemented some delegate methods in implementation file also.
When we tap on the UISearchBar
, a keyboard will appear to enter text. The return key of the keyboard is "Search" button. It will disabled by default. When we enter a character, It will get enabled. (Am I right?)
Here the problem comes.. I want to enable the UISearchBar
keyboard's return key when the user types atleast two letters.
Is it possible? If yes, how can we do it?
Thanks
You can't disable the search button. What you can do is use the UISearchBarDelegate
methods to figure out if you should take action on the search button being clicked, like so:
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
if (searchBar.text.length < 2) {
return;
}
else {
// Do search stuff here
}
}
The Apple Documentation for this is very useful as well, and is a great starting point for customizing the searchBar's behavior.
