iphone - Cocoa - UITableViewController strange behaviour ! -

i'm losing mind on this:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *myidentifier = @"cell";      uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:myidentifier];       uilabel *label;      if (cell == nil) {         cell = [[[uitableviewcell alloc] initwithframe:cgrectzero reuseidentifier:myidentifier] autorelease];         label=[[uilabel alloc]initwithframe:cgrectmake(20, 20, 200, 30)];         [cell addsubview:label];         [label settext:[nsstring stringwithformat: @"%d",indexpath.row]];     }      return cell; } 

in cells' labels, see numbers instead of progression expecting (0,1,2,3,4...):

0 1 2 0 4 1 2 0 4 1

any idea where's error? seems can't figure out.

edit resolved after putting initialization of label after cell==nil{} block.(don't know why put there in first place.)

you need perform cell configuration outside of if:

uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:myidentifier];  if (cell == nil) {     cell = [[[uitableviewcell alloc] initwithframe:cgrectzero reuseidentifier:myidentifier] autorelease];     uilabel *label=[[uilabel alloc]initwithframe:cgrectmake(20, 20, 200, 30)];     [cell addsubview:label];     [label release]; }     [label settext:[nsstring stringwithformat: @"%d",indexpath.row]]; 

oh - , should release label after adding avoid memory leak :)
