This may be related to using CADisplayLink. When openGL seems to be pushed a bit, touch events seem to drop or are delayed. When using NSTimer in ofxiPhoneAppDelegate instead of CADisplayLink this does not occur.

It may be beneficial for developers to set whether they'd like to use CADisplayLink (if available) vs NSTimer for rendering or not.

CADisplayLink has been disabled in the latest ios develop because of this issue.
not sure how important it is to get CADisplayLink working instead of NSTimer... rendering seems to be fine.
will keep this issue open for further investigation...

ofxiOS is still using NSTimer and haven't heard of any requests to use CADisplayLink instead.
