IOS collectionViewCell防止復用的兩種方法
collectionView 防止cell復用的方法一:
//在創建collectionView的時候注冊cell(一個分區)
UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:@“cell" forIndexPath:indexPath];
for (UIView *view in cell.contentView.subviews) {
[view removeFromSuperview];
}
collectionView 防止cell復用的方法二:
//在cellForItem方法中注冊cell(多個分區)
NSString *identifier=[NSString stringWithFormat:@"%ld%ld",(long)indexPath.section,(long)indexPath.row];
[collect registerClass:[UICollectionViewCell class] forCellWithReuseIdentifier:identifier];
UICollectionViewCell *cell=[collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];
for(id subView in cell.contentView.subviews){
if(subView){
[subView removeFromSuperview];
}
}
