Expandable and Collapsable UITableViewCell with Cu

问题:

Not Getting any Idea on how to solve this ....

Ok. This is my custom UITableViewCell with three different Child Views. That you can see with different colors.

Here , Height of my second Child View is dynamic and be calculated at run time. I am using -heightForRowAtIndexPath to set the height of UITableViewCell.

What I have tried :

I set the Outlets of Child Views and then in -heightForRowAtIndexPath , I used this Code...

middleView.frame = CGRectMake(0, 60.0, 750.0, size);
footerView.frame = CGRectMake(0, size + 60.0, 750.0, 50.0);

where, size = Dynamically Calculated Height of Middle View.

UPDATE :

I have also tried with static value of size like this ...

 middleView.frame = CGRectMake(0, 60.0, 750.0, 350.0);
 footerView.frame = CGRectMake(0, 350.0 + 60.0, 750.0, 50.0);

But No Luck at All....

Size is calculated by this : size = (elements * 30) + 50;

where , elements = Number of elements in the Array.

Problem :

Look, at the Screenshot.

Any Suggestions ?

Set your middle view and footer view frame in following method instead of heightForRowAtIndexPath:

and keep your other method as given by indra Mohan above.

 - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath       *)indexPath
{   
NSString * cellIdentifier = @"TableViewCellIdentifier"  ;
InAppTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

cell.delegate = self;
float size = [self heightForMiddleViewAtIndexPath: indexPath]
cell.middleView.frame = CGRectMake(0, 60.0, 750.0, size);
cell.footerView.frame = CGRectMake(0, size + 60.0, 750.0, 50.0);
return cell;

}

To solve this problem you have to do two things

1. set proper autoresizingMask to all your child views

       headerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin;
   middleView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
   footerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; 

   
   

2. return proper height from UITableViewDelegate method

   
   
   (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
   {
   return [self heightForMiddleViewAtIndexPath: indexPath] + footerViewHeight + headerViewheight;
   }
   (CGFloat)heightForMiddleViewAtIndexPath:(NSIndexPath *)indexPath
   {
   \ do some height calculation;
   }
