clear button in UISearchBar

问题

Hi can I remove clear button (X button)present in UISearchBar?

I didn't find any delegate for that. There is one for cancel button.

Thanks

回答1:

You can not directly access the clearButton of UISearchBar. You have to loop through the subviews of the UISearchBar to find the UITextField, and set its clearButtonMode property to UITextFieldViewModeNever.

Note: This is not a permanent solution because this may not work in future if the implementation of UISearchBar changes by the subsequent iOS updates.

回答2:

You need to get the textField of the Search Bar

UITextField *textField = [searchBar valueForKey:@"_searchField"];
textField.clearButtonMode = UITextFieldViewModeNever;

use in - searchBarTextDidBeginEditing method.

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
 {

UITextField *textField = [searchBar valueForKey:@"_searchField"];
textField.clearButtonMode = UITextFieldViewModeNever;


 }
