- Thread-topic: Scroller With CATiledLayer Running out of Memory
I have a very long text view (CoreText) for iPad. It a CATiledLayer, 1024 x
512 tiles. I'm doing optimized drawing (first to last line) in drawRect,
which gets called for each tile. I have a vertical slider that appears when
you tap the right side in order to fast (live) scroll when needed.
I'm having a major problem. If I scroll slowly, or in small jumps, no
problem. However, if I scroll fast over a longer length, the app terminates
with memory exceeded. I don't believe I have any significant leaks. This
doesn't happen in the simulator, only on the iPad. Am I simply outrunning
the app's ability to recover memory? What gives?
I notice that default fadeDuration for CATiledLayer is 0.25 sec. However, I
see no way to set this (i.e., to 0.0). Could this be related to my problem?
Any workarounds?
