IPhone : little problem of memory leak with NSTimer?

To my knowledge, you don't retain NSTimer objects because they are retained by the 'system'. And by doing an invalidate you release it from the system.

You don’t. The run loop retains the timer for you and releases it some time after you call the invalidate method, so that all you have to do is droping the extra retain in the call to scheduledTimerWithTimeInterval.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
