iphone - Custom clear button in UISearchBar text field

I tried:

UITextField *searchtextfield = [searchBar.subviews objectAtIndex:1];
    UIButton *cButton = [UIButton buttonWithType:UIButtonTypeCustom];
    cButton.frame = CGRectMake(0, 0, 20 , 20);
    cButton.backgroundColor = [UIColor clearColor];
    [cButton setImage:[UIImage imageNamed:@"x-button"] forState:UIControlStateNormal];//your button image.
    cButton.contentMode = UIViewContentModeScaleToFill;
    [cButton addTarget:self action:@selector(xButtonPressed) forControlEvents:UIControlEventTouchUpInside];//This is the custom event
    [searchtextfield setRightView:cButton];
    [searchtextfield setRightViewMode:UITextFieldViewModeWhileEditing];

But it doesn't work very well... It displays custom button, but when you type something, the old one get's back...

How can I do this?

If you want to set a custom clear button in a UISearchBar try this:

[[UISearchBar appearance] setImage:[UIImage imageNamed:@"MyClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateNormal];

Don't forget to set an image for UIControlStateHighlighted

[[UISearchBar appearance] setImage:[UIImage imageNamed:@"HighlightedClearButton.png"] forSearchBarIcon:UISearchBarIconClear state:UIControlStateHighlighted];
