Question

Already the second day and cannot figure out the problem,

I’ve UITabelView with Custom UICellViews, each custom UICellView consists of UILabel and UITextField.

Custom UICellView object allocs UITextField and UILabel in its init method and are released in dealloc.

The number of custom UICellViews in UITableView is 6.

The user scenario is following

• When user clicks from from 1 to 5 UITextFields virtual keyboard opens and user types some text
• When user clicks on the 6th UITextField if virtual keyboard is active, it should be hidden, and if it is hidden it shall not be displayed.

As implement UITextFieldDelegate protocol in my UIViewController class and set the delegate of each UITextField to self.

My delegate methods are following

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    if (textField.tag != 6) {
        return YES;
    } else {
        [textField resignFirstResponder];
        return NO;
    }
}

-(BOOL)  textFieldShouldEndEditing:(UITextField *)textField {
    [textField resignFirstResponder];
    return YES;
}

-(void) textFieldDidBeginEditing:(UITextField *)textField {
     /* Some code */
}

-(void) textFieldDidEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
}

All the functions are properly !

So now, the virtual keyboard is never get hidden, why this happens ?

PS. Similar code has worked on iPhone but this issue exists on iPad.

Answer 1

You need to know which textfield was last used! so you can do [lastUsedTextField resignFirstResponder]

There is a dirty, but working trick.. you can make your textfield the new active UITextField and call resignFirstResponder in the next cycle immediately:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField
{
    if (textField.tag != 6) {
        return YES;
    } else {
        // this will schedule keyboard dismissal for the current text field
        dispatch_async(dispatch_get_main_queue(), ^{
            [textField resignFirstResponder];
        });
        return YES; // -> make this one active
    }
}
