iPhone: How to remove glow (light) from UIBarButtonItem when pressed?

问题

I'm trying to remove the glow from a UIBarButton item so that my text appears to be a label instead of a button. I've seen various posts talking about how to do this through interface builder or by setting a boolean variable "showsTouchWhenHighlighted", but neither of these options are available to me it appears. I've tried setting the showsTouchWhenHighlighted in the .m viewDidLoad where I change the font and font-size but the UIBarButtonItem doesn't appear to have that property. I also only have the options in the following image to change in InterfaceBuilder.

There is a way to do this (a bit of a hack but it works). Just drag a UIButton into your toolbar (instead of a UIBarButtonItem). Then a UIBarButtonItem will be automatically be created for you as a superview for your UIButton. Then you just set it like this:

UIBarButtonItem

Style: Plain
Title: (empty)

UIButton

Type: Custom
Title: (your actual label title here)
Text Color: White
Shows Touch On Highlight: (Unchecked)

Here is a screenshot to use as reference:

Note: Just remember that from now on any updates on the text must be made on the UIButton

try this:

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(140 , 0, 50, 250)];
    [label setBackgroundColor:[UIColor clearColor]];
    label.text = @"TEXT";
    UIView *view = (UIView *) label;
    [self.barItem setCustomView:view];

note: self.barItem is a UIBarButtonItem added from the object library and placed between two flexible spaces.

another way is to remove the [self.barItem setCustom:view] line and change the parameters of the label (width) so that it fills the entire toolbar and set the alignment to middle and the font by yourself in code,
