Bind button title to Boolean
How can I bind a button title to a Boolean but have a custom title for each state? For example, I have a BOOL isRunning, if YES, my button should read Stop Running else Start Running. I can't really do this with an alternate title since when the button is pushed and temporarily held down, the title should not change as it is a normal push pill button.

I know I can write a value transformer, but is there a simple way to do such a two state button title in IB and just provide it my isRunning method? It seems like a common enough default situation.

How about something like this? Whenever isRunning changes, it
triggers an update of the button's title.
+ (void) initialize
{
...
[self setKeys:[NSArray arrayWithObject:@isRunning]
triggerChangeNotificationsForDependentKey:@buttonTitle];
...
}
- (NSString*) buttonTitle
{
return [self isRunning] ? @Stop Running : @Start Running;
}
- (BOOL) isRunning
{
return _isRunning;
}
- (void) setIsRunning:(BOOL)isRunning
{
[self willChangeValueForKey:@isRunning];
_isRunning = isRunning;
[self didChangeValueForKey:@isRunning];
}
