New issue 31 by binarynights: PSMTabBarControl - Exception while animating
http://code.google.com/p/maccode/issues/detail?id=31
When rearranging tabs it crashes often with the folowing exception:
*** Canceling drag because exception 'NSGenericException' (reason '***
Collection <NSCFSet:
0x168333d0> was mutated while being enumerated.') was raised during a
dragging session
Somehow I can't reproduce this with the example app but with my app it
always happens.
Could be that I create the PSMTabBarControl programatically, but I'm not
sure...
Anyway, I could fix this by copying the NSMutableSet before enumerating.
Hope this helps.
- (void)animateDrag:(NSTimer *)timer
{
NSEnumerator *e = [[_participatingTabBars copy] objectEnumerator];
....
}
