ios - UICollectionView reloadData issue - cell's subview issue -

i have maked following view.

but when calling -reloaddata, view becomes...

i think it's because cells reused.
have idea keep view first image if calling reloaddata?

- (uicollectionviewcell *)collectionview:(uicollectionview *)collectionview cellforitematindexpath:(nsindexpath *)indexpath {     customcell* cell = [collectionview dequeuereusablecellwithreuseidentifier:kcellidentifier forindexpath:indexpath];      if (indexpath.item == 0)     {         cell.label.text = @"hello";     }     else     {         uiimage *image = dataarray[indexpath.item];         cell.imageview.image = image;     }      return cell; } 

customcell.m

@property (nonatomic, strong) uiimageview* imageview; @property (nonatomic, strong) uilabel* label;  //...  - (id)initwithframe:(cgrect)frame {     self = [super initwithframe:frame];     if (self)     {                 self.imageview = [[uiimageview alloc]initwithframe:imgviewframe];         [self.contentview addsubview:self.imageview];          self.label = [[uilabel alloc]initwithframe:labelframe];         [self.contentview addsubview:self.label];     }     return self; } 

edit:

i modified code.
- setting default values before setting them correct data
- calling -prepareforreuse
when calling -reloaddata, although imageview.image stay nil, label.text in indexpath.item==0 becomes nil , label.text in indexpath.item==3 outputs @"hello".

yes, because of reusability. can avoid changing line of code this:

if (indexpath.item == 0) {     cell.label.text = @"hello";     cell.imageview.image = nil; } else {     uiimage *image = dataarray[indexpath.item];     cell.imageview.image = image;     cell.label.text = @""; }
