What if tDelegate == delegate?
You release delegate, which *may* dealloc it. Then you assign
tDelegate to it. If tDelegate == delegate (not uncommon that objects
are the same) then you've assigned a stale pointer. The following -
retain is too late.
The correct pattern is always "retain before release", i.e.:
[tDelegate retain];
[delegate release];
delegate = tDelegate;
Not sure if it has a bearing on your problem, but make sure the
obvious bugs are fixed first.
But in any case, you shouldn't be retaining your delegate. See the doc
link I posted a second ago.
