ios - After using self sizing cells reloadData doesn't work anymore -


i have uitableview custom cell. there button, 1 label , 1 hidden label in cell. want hidden label visible after clicking button. when using self sizing cells can't reload tableview after setting hidden label visible.

the self sizing cells working fine these 2 lines of code in viewdidload() function.

self.tableview.estimatedrowheight = 68.0 self.tableview.rowheight = uitableviewautomaticdimension

this viewcontroller class:

class viewcontroller: uiviewcontroller, uitableviewdatasource, uitableviewdelegate {  @iboutlet weak var tableview: uitableview! override func viewdidload() {     super.viewdidload()      //self sizing cells     self.tableview.estimatedrowheight = 68.0     self.tableview.rowheight = uitableviewautomaticdimension }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }  func tableview(tableview: uitableview, numberofrowsinsection section: int) -> int {     return 1 }  func tableview(tableview: uitableview, cellforrowatindexpath indexpath: nsindexpath) -> uitableviewcell {     var cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) as! customcell     cell.leftlabel.text = "left label"     cell.centerlabel.text = "i center label , need little more words because supposed wrap content. hope enough"     cell.button.tag = indexpath.row     cell.button.addtarget(self, action: "buttonaction:", forcontrolevents: uicontrolevents.touchupinside)     return cell }  func buttonaction(sender: anyobject) {     var button: uibutton = sender as! uibutton     let indexpath: nsindexpath = nsindexpath(forrow: button.tag, insection: 0)     var cell = tableview.dequeuereusablecellwithidentifier("cell", forindexpath: indexpath) as! customcell     cell.centerlabel.hidden = false     self.tableview.reloaddata() } }

as call 

self.tableview.estimatedrowheight = 68.0

the reloaddata call in buttonaction function doesn't work anymore.

can me out problem? thanks!

try this. use cellforrowatindexpath grab cell @ position in tableview, not dequeuereusablecellwithidentifier

func buttonaction(sender: uibutton) {     var indexpath:nsindexpath = nsindexpath(forrow:sender.tag, insection: 0)     var cell = tableview.cellforrowatindexpath(indexpath) as! customcell     cell.centerlabel.hidden = false }

then if want hide centerlabel when cells reused, add method in customcell class

override func prepareforreuse() {     self.centerlabel.hidden = true }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
