ios - UiTableView label word wrap -

i define separate uilabel class margin label in cell:

- (void)drawtextinrect:(cgrect)rect {     uiedgeinsets insets = {5, 10,5, 10};     [super drawtextinrect:uiedgeinsetsinsetrect(rect, insets)];  } 

with following code, define height cell:

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath{     if (!self.customcell) {         self.customcell = [self.chattableview dequeuereusablecellwithidentifier:@"cellchat"];     }      self.customcell.sender.text = [array objectatindex:indexpath.row];      [self.customcell layoutifneeded];      cgfloat height = [self.customcell.contentview systemlayoutsizefittingsize:uilayoutfittingcompressedsize].height;      return height +1;  } 

my question: when test application not take word wrap on right place. why? have uilabel class?

edit:

thanks, still doesn't work. don't have error, when load table view not display text. @ moment, code looks that:

imports:

#import "chatviewcontroller.h" #import "chattableviewcell.h"  @interface chatviewcontroller ()  @property (strong, nonatomic) chattableviewcell *customcell;  @end 

next:

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath{     uilabel *gettingsizelabel = [[uilabel alloc] init];     gettingsizelabel.font = [uifont fontwithname:@"arial" size:15];     pfobject *tempobject = [array objectatindex:indexpath.row];     gettingsizelabel.text = [tempobject objectforkey:@"sender"];     gettingsizelabel.numberoflines = 0;      cgsize maximumlabelsize = cgsizemake(140, maxfloat);     cgsize expectedsize = [gettingsizelabel sizethatfits:maximumlabelsize];      return expectedsize.height + (10*2); } 

my cellforrowatindexpath:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifer = @"cellchat";      chattableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifer];      pfobject *tempobject = [array objectatindex:indexpath.row];     cell.sender.text = [tempobject objectforkey:@"sender"];     cell.receptor.text = [tempobject objectforkey:@"receptor"];     cell.sender.linebreakmode = nslinebreakbywordwrapping;     cell.sender.numberoflines = 0;      return cell; } 

edit

do not use self.customcell inside - (cgfloat)tableview:tableview heightforrowatindexpath:indexpath

instead, calculate cell height this:

- (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath{      uilabel *gettingsizelabel = [[uilabel alloc] init];     gettingsizelabel.font = font;     gettingsizelabel.text = [array objectatindex:indexpath.row];  // text inside [array objectatindex:indexpath.row];     gettingsizelabel.numberoflines = 0;      cgsize maximumlabelsize = cgsizemake(yourmaxwidth, maxfloat);      cgsize expectedsize = [gettingsizelabel sizethatfits:maximumlabelsize];      return expectedsize.height /*then add margin 'y' margin multiplied 2 top , bottom margin*/; } 

and dont forget set

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellid = @"cellchat";      self.customcell = [tableview dequeuereusablecellwithidentifier:cellid];      if (!self.customcell)     {         self.customcell = [[yourcellclass alloc] initwithstyle:uitableviewcellstyledefault reuseidentifier:cellid];     }      // dont forget set      self.customcell.textlabel.linebreakmode = nslinebreakbywordwrapping;     self.customcell.textlabel.numberoflines = 0;     // [self.customcell sizetofit]; optional depending want     return self.customcell; } 

hope have helped you, happy coding.. cheers! :)
