Clear button at uisearchbar not working at all
- by kevin.ng
I created a search bar programmatically and added to my view using the codes below:
- (void)viewDidLoad
{
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(xPositionForSearchBar, yPositionForSearchBar, widthForSearchBar, heightForSearchBar)];
UIView *bg = [[searchBar subviews] objectAtIndex:0];
searchBar.delegate = self;
searchBar.placeholder = @"Search record";
for(UIView *view in searchBar.subviews){
if([view isKindOfClass:[UITextField class]]){
UITextField *tf = (UITextField *)view;
tf.delegate = self;
break;
}
}
[bg removeFromSuperview];
[self.view addSubview: searchBar];
}
The code is implemented with UISearchBarDelegate and UITextFieldDelegate.
I have tried using
- (void)searchBarCancelButtonClicked:(UISearchBar *)aSearchBar
{
NSLog(@"cancel clicked");
searchBar.text = @"";
[aSearchBar resignFirstResponder];
}
- (BOOL)textFieldShouldClear:(UITextField *)textField
{
NSLog(@"clear");
[self performSelector:@selector(searchBarCancelButtonClicked:) withObject:searchBar afterDelay: 0.1];
return YES;
}
and yet, the text inside the searchBar is not cleared at all when i click on the "clear button" - a circle with a "X" inside.
The clear button works when I implemented it in IB. Wonder why?
Kindly advice, many thanks.
