iOS tableView编辑删除（单选 多选）

viewDidload 添加

for (int i = 0; i <_reouseArray.count ; i++) {
NSMutableDictionary *dictionary = [NSMutableDictionary dictionary];
[dictionary setValue:@"NO" forKey:[NSString stringWithFormat:@"%d", i]];
[_contacts addObject:dictionary];
}

cellForRow中进行赋值

NSMutableDictionary *dictionary = [_contacts objectAtIndex:[indexPath row]];
if ([[dictionary objectForKey:keyForChecked] isEqualToString:@"NO"]) {
[dictionary setObject:@"NO" forKey:keyForChecked];
[_showMediaCell setChecked:NO];

}else {
[dic_material setObject:@"YES" forKey:keyForChecked];
[_showMediaCell setChecked:YES];

}

#define keyForChecked [NSString stringWithFormat:@"%ld", (long)indexPath.row]

<pre name="code" class="objc">didSelect方法获取单个点击／取消操作

-(void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {

[collectionView deselectItemAtIndexPath:indexPath animated:YES];

自定义cell中

<pre name="code" class="objc">- (void)setChecked:(BOOL)checked{
if (checked)
{
[_selectBtn setImage:[UIImage imageNamed:@"选择2"] forState:(UIControlStateNormal)];
}
else
{
[_selectBtn setImage:[UIImage imageNamed:@"选择1"] forState:(UIControlStateNormal)];
}
_checkedForSelect = checked;
}
