This may be a simple question but i wish to through the correct path.

Im fetching some contents from the webservice and displaying it in a table view.

The length of text that is fetching from there may vary.

Sometime it may have only one line sentence,sometime a paragraph etc.

So my doubt is how can i vary the height of custom cell according to the content coming from webservice.

Hoping for your help.

Thanks in advance.

In you UITableViewDelegate implement the following method

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

returning the proper height according to the row.

you can use the method -sizeWithFont: of NSString to get the pixel size of the text you get.

Let's assume you store the text for each content in an array. And the index lined up with the table cell. Here is the code you want to use. 

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *string = [array objectAtIndex:indexPath.row];

//300 is the width, you can change this to make it look right.
CGSize maximumLabelSize = CGSizeMake(300 ,9999);
CGSize expectedLabelSize = [string sizeWithFont:YOURLABEL.font 
                                    constrainedToSize:maximumLabelSize 
                                        lineBreakMode: UILineBreakModeWordWrap]; 

return expectedLabelSize.height;

}

Pretty much covers the basic. Just ask if you have any more questions. And read Leena's comment. It is pretty spot on.
