iPhone中的自动tableView单元格大小是多少？

Question

I want to make a UITableView which automatically adjust it's cell size by it's contents.

The contents are from XML file and the data is just text.

I want to put the text in a cell and it should be automatically does word-wrap and support multi-line.

So each cell can have different height. Is this possible?? or any idea?

Thank you ;)

Answer 1

Yes it is possible. Make use of the following method for doing it,

- (CGFloat)tableView:(UITableView *) tableView heightForRowAtIndexPath: (NSIndexPath *)indexPath    {
CGSize cellHeight;
if (indexPath.row == 0) {
    cellHeight = [yourXMLContents sizeWithFont:[UIFont systemFontOfSize:13.0f] constrainedToSize:CGSizeMake(300.0, 1000.0) lineBreakMode:UILineBreakModeWordWrap];
    return cellHeight.height + 20;
}  else 
    return  30;

}

Have you looked at the three20 library ? It'll resize the cells to fit the content. In the very least, you can look at how the code is implemented to resize cells.
