NSButton does not show alternative Title since SDK update?

Question

Background Information:

I've recently upgraded from Lion to MountainLion and the newest xCode. The app im working on has deployment target 10.7.

Problem:

I've a NSButton setup in the Interfacebuilder with Title: "Start" and Alternate: "Stop". In the buttons IBAction I check the state of the application (BOOL isRunning) and change the state every time the button is pressed like this:

[startStopButton setState:[appDelegate.dataController appIsRunning]];

Everything worked fine. Since I upgraded to the new xCode the button does not change the title anymore.

Things I already tried out:

• Checked all the connections between IBAction and IBOutlet according this button. Reset everything up. Did not help.
• Created a new NSButton tried the same. Did not work.

• Setting the titles via code: Did not work.

  [startStopButton setTitle:@"Start"];
  [startStopButton setAlternateTitle:@"Stop"];
  

• Thought it may have been a problem with the boolean value. So I checked if the button is not in mixed mode. Then hardcoded statechanges with 1 and 0 from type int. No change at all.

• Somehow when I use [startStopButton setTitle:@"TEST"] and then change the state, it changes the state ONCE to alternate but not back anymore. The "TEST" String is never seen on the button also...

• I logged the value of [appDelegate.dataController appIsRunning] and it returns the correct values.

I have no clue how to solve this. Everything worked fine, I changed nothing and it doesn't make any sense to me. Has anybody encountered a equivalent problem?

Answer 1

In Interface Builder, change the button type to "Toggle". I'm not sure of the reason, but it appears that alternate title does not work for "Momentary" and "Push" button types.
