Hi!

If I am setting a the tintColor to my navigation bar, the effect of "clicking a button" disappears. I still can click the button, but the button does not turn "darker" anymore, when getting clicked.

The same thing happens, if I am adding a custom uiToolbar to my navigation bar. As long as I am not setting the tintColor, the button-press-effect is working..

    Can you give any code samples?

    Hi Alex -

    I played with tints and bars in the attempt to answer a similar question recently posted by Luther Baker: [http://discussions.apple.com/message.jspa?messageID=10829363#10829363]. I was unable to do what Luther needed in my testbed, but you only need the first half of his requirements, so I may have learned enough to help.

    Firstly, I discovered that applying a tint in IB would work correctly for both nav and tool bars. However for some reason, if I set the tint programmatically in viewDidLoad, the tool bar controls no longer displayed the highlight (darker) color correctly. I don't remember doing the same test on a nav bar, but I can tell you that getting custom controls to pick up the bar tint is much easier with a nav bar.

    The next question is, "At what point in the life cycle of a tool bar should it be tinted?". I didn't get far enough to answer that, and being clueless about the mechanism didn't help. It might be that the tint needs to be set before the controls are added, and/or before the bar is added to the superview, but I haven't yet tried all the possibilities.

    So my short answer is: Make the toolbar with its controls and add it to the content view in IB. That might exclude using the toolbar that belongs to a nav controller.

    If you must build the toolbar programmatically, someone will need to find the correct point in the creation and load sequence to set the tint. Hopefully I can find my BarTint testbed if further research is necessary.
