OUIEditableFrame performance issues Thread Tools Search this Thread Display Modes
Prev Previous Post   Next Post Next
I am seeing some performance issues with OUIEditableFrame when it is run on the original iPad.

When there is a fair amount of text in the frame say 180 lines, typing/input lags greatly behind and one tap on a key using takes 1-2 seconds. This also considering there is nothing in any of the delegate methods.

Using instruments with the simulator I was able to narrow down the problem and find out what was taking so much time. Turns out it's because the frame is redrawn with every key stroke, what takes up so much time is calling CTFramesetterCreateWithAttributedString and CTFramesetterCreateFrame.

Have any of you realized this or is there something I'm doing that's caused this?
