ios - Hide label in TableViewCell when swipe to delete -


i want able hide label in uitableviewcell in order stop overlapping title whenever user swipes delete cell.

i'm using following code initiate , handle swipe delete:

- (void)tableview:(uitableview *)tableview commiteditingstyle:(uitableviewcelleditingstyle)editingstyle forrowatindexpath:(nsindexpath *)indexpath {      if (editingstyle == uitableviewcelleditingstyledelete) {          [self.tableview beginupdates]; // avoid  nsinternalinconsistencyexception          // delete project object swiped         project *projecttodelete = [self.fetchedresultscontroller objectatindexpath:indexpath];         nslog(@"deleting (%@)", projecttodelete.name);         [self.managedobjectcontext deleteobject:projecttodelete];         [self.managedobjectcontext save:nil];          // delete (now empty) row on table         [self.tableview deleterowsatindexpaths:[nsarray arraywithobject:indexpath] withrowanimation:uitableviewrowanimationleft];         [self performfetch];          [self.tableview endupdates];     } } 

i've assigned label in cell using:

uilabel *projectdate = (uilabel *)[cell viewwithtag:3];     projectdate.text = project.datestarted; 

and have tried setting

projectdate.hidden = yes;  

however, not work.

i think you'll need subclass uitableviewcell implement this. in subclass override - (void) setediting:(bool)editing animated:(bool)animated. in method can hide label. if need hide label delete operations, use self.editingstyle conditionally hide label depending on editing style (aka: uitableviewcelleditingstyledelete).

here 2 examples. prefer example two, it's easier. example 1 let replace text, might useful:

@implementation cellsubclass{     nsstring *_labeltext; //only used in example 1 }  - (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 } // example 1, replacing text value - (void) setediting:(bool)editing animated:(bool)animated{     [super setediting:editing animated:animated];     if (editing && self.editingstyle == uitableviewcelleditingstyledelete){         uilabel *label = (uilabel *)[self viewwithtag:3];         _labeltext = label.text;         self.textlabel.text = nil;     }  else if (!editing && _labeltext){         uilabel *label = (uilabel *)[self viewwithtag:3];         label.text = _labeltext;     } }  //example 2 - hiding view - (void) setediting:(bool)editing animated:(bool)animated{     [super setediting:editing animated:animated];     if (editing && self.editingstyle == uitableviewcelleditingstyledelete){         [self viewwithtag:3].alpha = 0.0f;     } else {         [self viewwithtag:3].alpha = 1.0f;     } }  @end 

please, please note have 2 methods same name. big no-no....use 1 of them.

also note ignored animated parameter. if want disappearance of label animated in second example (aka...fade away/fade in) need surround changes in animation block, so:

        [uiview animatewithduration:.3f animations:^{             [self viewwithtag:3].alpha = 0.0f;         }];  

i don't think can animate first example.
