从tableViewCell发件人返回错误的UIButton

Question

对于ios 7和大部分，返回的单元格总是第一个单元，即indexpath.row =0。尽管我考虑的是单元格内的滚动视图和额外的.superview。

- (UITableViewCell *)getCellforButton:(UIButton *)sender
{
    UITableViewCell *cell;

    //Check for iOS version and get the cell accordingly
    NSArray *versionComponenets = [[UIDevice currentDevice].systemVersion componentsSeparatedByString:@"."];

    if ([[versionComponenets objectAtIndex:0] intValue] >= 7)
    {
        // iOS-7 code[current] or greater
        //Additional superview call to account for new scrollview inside of cells
        cell = (UITableViewCell *)sender.superview.superview.superview;
    }
    else
    {
        // iOS-6 code
        cell = (UITableViewCell *)sender.superview.superview;
    }

    return cell;
}

使用UIView's convertPoint:toView method获取UITableViewCell

-(UITableViewCell *)getCellforButton:(UIButton *)sender
{
    CGPoint btnPosition = [sender convertPoint:CGPointZero toView:yourTableViewHere];
    NSLog(@"btnPositionn : %@",NSStringFromCGPoint(btnPosition));
    NSIndexPath *curIndexPath = [yourTableViewHere indexPathForRowAtPoint:btnPosition];
    id cell = [yourTableViewHere cellForRowAtIndexPath:curIndexPath];
    if (cell)
    {
        UITableViewCell *curCell = cell;
        return curCell;
    }
    else
        return nil
 }
