ios - UIRefresh without visually reloading entire table -

i have uitableview , have pull refresh working empty arrays, gets data fill them ,and reloads table. custom animation, looks bad whole table disappears , reanimates in. want update data , add in row or remove 1 if needed without flickering entire table. here gif of happens: https://giphy.com/gifs/8d4ullrr2qtlm

code animate table cell:

func tableview(tableview: uitableview, willdisplaycell cell: uitableviewcell, forrowatindexpath indexpath: nsindexpath) {       var cellcontentview: uiview = cell.contentview      var rotationangledegrees: cgfloat = -30      var rotationangleradians: cgfloat = rotationangledegrees * (3.14159 / 180)      var offsetpositioning: cgpoint = cgpointmake(500, -20.0)      var transform: catransform3d = catransform3didentity      transform = catransform3drotate(transform, rotationangleradians, -50.0, 0.0, 1.0)      transform = catransform3dtranslate(transform, offsetpositioning.x, offsetpositioning.y, -50.0)      cellcontentview.layer.transform = transform      cellcontentview.layer.opacity = 0.8      uiview.animatewithduration(0.65, delay: 0.0, usingspringwithdamping: 0.85, initialspringvelocity: 0.8, options: [], animations: {() -> void in      cellcontentview.layer.transform = catransform3didentity      cellcontentview.layer.opacity = 1      }, completion: {(finished: bool) -> void in      })  } 

code refresh control:

func refresh(sender: anyobject) {      namearray = []     textarray = []     userarray = []     latarray = []     longarray = []     timearray = []     loctextarray = []     category = []     eventid = []     pricearray = []      getdata()  // gets server data      tableview.reloaddata()      refreshcontrol?.endrefreshing() }
