Using a UISearchBar with showCancelButton=YES on iOS 5. Would like the cancel button to stay enabled when the keyboard drops down. Using the following code seems not to work:<
I know this one is old, but I was able to solve it and I couldn't find anything else on SO that solved it for me, so here's what worked (in Swift 3):
Enable the cancel button when the keyboard hides. Add this to viewDidLoad():
NotificationCenter.default.addObserver(self, selector: #selector(self.keyboardNotification(notification:)), name: NSNotification.Name.UIKeyboardDidHide, object: nil)
in the keyboardNotification(notification:) method, react to the keyboardDidHide notification:
func keyboardNotification(notification: NSNotification) {
if notification.name == Notification.Name.UIKeyboardDidHide {
self.enableSearchCancelButton()
}
}
The enableSearchCancelButton is taken from what others have answered here.
func enableSearchCancelButton() {
//enable the cancel button
for view1 in searchBar.subviews {
for view2 in view1.subviews {
if let button = view2 as? UIButton {
button.isEnabled = true
button.isUserInteractionEnabled = true
}
}
}
}
Finally, don't forget to remove the view controller as an observer:
deinit {
NotificationCenter.default.removeObserver(self)
}
Just to improve upon what Kurt Spindler said on his post. Though this might not be superior but it is more contained. I use dispatch to do the same thing.
-(void)searchBarTextDidEndEditing:(UISearchBar *)searchBar{
for (UIView *subview in searchBar.subviews)
{
if ([subview isKindOfClass:[UIButton class]])
{
int64_t delayInSeconds = .001;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
UIButton * cancelButton = (UIButton *)subview;
[cancelButton setEnabled:YES];
});
break;
}
}
}
This should work for everyone who needs help keep cancel enabled. Make sure that you hide it later either with the cancel or Search clicked.
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar{
[searchBar resignFirstResponder];
[searchBar setShowsCancelButton:NO animated:YES];
}
Swift 5:, Swift 4:
if let btnCancel = searchBar.value(forKey: "cancelButton") as? UIButton {
btnCancel.isEnabled = true
}
I had to solve the same problem in my application. Try doing your above code after a fractional delay, e.g.
[self performSelector:@selector(delayedEnable:) withObject:cancelButton afterDelay:0.001];
- (void)delayedEnable:(UIButton*)button {
button.enabled = YES;
}
It's ugly, but that's what it took to work for me. Alternatively, if you actually use a UISearchDisplayController to display the results, it should also fix the cancel button behavior for you (I think - I've delved into this issue less).
I placed a custom cancel button over the search bar cancel button.
Set your searchbar delegate and than put this code.
- (void) searchBarSearchButtonClicked:(UISearchBar*) theSearchBar
{
[theSearchBar resignFirstResponder];
[theSearchBar setShowsCancelButton:NO animated:YES];
}
- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar
{
[searchBar setShowsCancelButton:YES animated:YES];
}
- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
[searchBar resignFirstResponder];
[searchBar setShowsCancelButton:NO animated:YES];
}
Swift 3.0
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder()
searchBar.setShowsCancelButton(false, animated: true)
}
func searchBarTextDidBeginEditing(_ searchBar: UISearchBar) {
searchBar.setShowsCancelButton(true, animated: true)
}
func searchBarCancelButtonClicked(_ searchBar: UISearchBar) {
searchBar.resignFirstResponder()
searchBar.setShowsCancelButton(false, animated: true)
}
