In my application, I am adding a UISearchBar.
My intent is to enable the UISearch Bar "X button"(clear button in UITextField) to be always visible.
I have tried using the following code below to try to make the "X Button" be always visible. However, it does not work. If I set tf.clearButtonMode = UITextFieldViewModeNever
, the clear button in uitextfield not showing. I am not sure what is wrong?
I would really appreciate anyone's help here. Why is this not working?
Code (Not working)
for (UIView* v in searchBar.subviews)
{
if ( [v isKindOfClass: [UITextField class]] )
{
UITextField *tf = (UITextField *)v;
tf.delegate = self;
tf.clearButtonMode = UITextFieldViewModeAlways;
break;
}
}
Goal:
I want to always show the clear button if the text length is equal to 0
- i.e. if I don't input any text.
You have to need create a Custom UIButton for clear button
UIButton *clearButton = [UIButton buttonWithType:UIButtonTypeCustom];
[clearButton setImage:img forState:UIControlStateNormal];
[clearButton setFrame:frame];
[clearButton addTarget:self action:@selector(clearTextField:) forControlEvents:UIControlEventTouchUpInside];
textField.rightViewMode = UITextFieldViewModeAlways; //can be changed to UITextFieldViewModeNever, UITextFieldViewModeWhileEditing, UITextFieldViewModeUnlessEditing
[textField setRightView:clearButton];
UITextField *searchBarTextField = nil;
for (UIView *subview in self.searchBar.subviews)
{
if ([subview isKindOfClass:[UITextField class]])
{
searchBarTextField = (UITextField *)subview;
searchBarTextField.clearButtonMode = UITextFieldViewModeAlways;
break;
}
}
This is the default behavior of the search bar. Because if the UITextField
is blank then there is no need to press it.
U can do it in Xib. I am attaching the screenshot.
And programmatically
myUITextField.clearButtonMode = UITextFieldViewModeAlways;
I tried to get it but unfortunately , There is no Way of Customising with the ClearButton(X) of UITextField .
There is a way that If You only need it to get resign the KeyBoard , Then just overriding this method :
Just clear the field yourself and call resignFirstResponder .
-(BOOL)textFieldShouldClear:(UITextField *)textField
{
textField.text = @"";
[textField resignFirstResponder];
return NO;
}
