ios - Trying to detect if tableview scroll is over indexpath.row 0 -


i trying determine if user has scrolled beyond top of table can refresh it. far, have been unsuccessful because seem getting unique situation:

if (indexpath.row < 0) {

the above not work.

 if (_tableview.contentoffset.y < -64) {

this works, when pull extremely far (pull content bottom of tableview work). somehow need make need pull little bit, oddly enough, when put @ -63 reacts though @ -64 , continually refreshes.

if(self.tableview.contentoffset.y < (self.tableview.contentsize.height - self.tableview.bounds.size.height)) {

this works, when pull extremely far (pull content bottom of tableview work). somehow need make need pull little bit, oddly enough, when put @ -63 reacts though @ -64 , continually refreshes.
