iphone - UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath -

-

i have search @ https://stackoverflow.com/search?q=uitableview+datasource+must+return+a+cell+from+tableview%3acellforrowatindexpath ,but know need check if cell nil,but cell custom,and not use xib,i use storyboard.i choice class customplacetableviewcell @ storyboard.as http://i.stack.imgur.com/g0rro.png

code: 

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { customplacetableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];      //if ([cell iskindofclass:[customplacetableviewcell class]]) { cell = (customplacetableviewcell *)cell; } //retrieve place info place *place = [self.placedatacontroller objectinplacelistatindex:indexpath.row];  //set cell place info if (place.name) {     cell.namelabel.text =place.name; } else {     cell.namelabel.text = @"portaura"; }   if (place.distance) {     cell.distancelabel.text = place.distance;     } else {     cell.distancelabel.text = @"portaura"; }     return cell;  }   customplacetableviewcell.m @interface customplacetableviewcell : uitableviewcell{   uilabel *namelabel;   uilabel *distancelabel;   uilabel *addresslabel; } @property (nonatomic) iboutlet uilabel *namelabel; @property (nonatomic) iboutlet uilabel *distancelabel; @property (nonatomic) iboutlet uilabel *addresslabel;  @end      @implementation customplacetableviewcell    @synthesize distancelabel,namelabel,addresslabel;    - (id)initwithstyle:(uitableviewcellstyle)style reuseidentifier:(nsstring *)reuseidentifier  {     self = [super initwithstyle:style reuseidentifier:reuseidentifier]; if (self) {     // initialization code   }  return self; }   - (void)setselected:(bool)selected animated:(bool)animated {   [super setselected:selected animated:animated];    // configure view selected state  }   @end

when run app ,it give me :

2012-07-02 17:16:26.675 myaura[2595:707] *** terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'uitableview datasource must return cell tableview:cellforrowatindexpath:'

i think miss return cell in tableview:cellforrowatindexpath try this

return cell;

ans check or use nslog(@"description = %@",[cell description]);

if [cell description] null change it

customplacetableviewcell *cell = (customplacetableviewcell*) [tableview dequeuereusablecellwithidentifier:cellidentifier];

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
