Not according to the docs:
+ (NSTimer *)scheduledTimerWithTimeInterval:(NSTimeInterval)seconds
invocation:(NSInvocation *)invocation repeats:(BOOL)repeats
Returns a new NSTimer object and adds it to the current NSRunLoop in the
default mode. After seconds have elapsed, the timer fires, sending the
message in invocation to its target. If seconds is less than or equal to
0.0, this method chooses a nonnegative interval. If repeats is YES, the
timer will repeatedly reschedule itself until invalidated. If repeats is NO,
the timer will be invalidated after it fires.

I think you need to add something like
[[NSRunLoop currentRunLoop] addTimer: timer forMode:
NSDefaultRunLoopMode];
for your timers in order to have the run loop run them; otherwise, I think
you've created objects that actually aren't going to do anything but sit
there.

Here's my code, do you see anything wrong?
