facebook ios

they using custom uitableview

finally, when start facebook ios, want see news feed, not loading spinner. provide best experience possible, show previously-cached content immediately. introduces new problem: if have lot of stories in news feed, uitableview throws small spanner in works calling delegate method -tableview:heightforrowatindexpath: each story in news feed in order work out how tall make scrollbar. result in app loading story data disk , calculating entire story layout solely return height of story, meaning startup progressively slower accumulate more stories.
