How to Wrap Text in UITableViewCell ?

[satyanarayanagv]

Hi,

We have large text which is to be displayed in a UITableViewCell .
We need to view the entire text in the cell but it displays some part of the text with "..." at the ending. Can any one suggest the relevant approach to wrap text in our customized UITableViewCell?
or else Is there any option to display Tooltip on touching UITableViewcell of UITableView in iphone SDK?

Thanks
Satya

I have a two line text area for my table rows. Here is how I did it (though I did some fudging with absolute pixel values for offsets):

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
    }
    
    CGRect contentRect = CGRectMake(80.0, 0.0, 240, 40);
    UILabel *textView = [[UILabel alloc] initWithFrame:contentRect];
	
	textView.text = mytext;
	textView.numberOfLines = 2;
	textView.textColor = [UIColor grayColor];
	textView.font = [UIFont systemFontOfSize:12];
        [cell.contentView addSubview:textView];
	[textView release];

I have this code in the cellForRowAtIndexPath method for the tableView delegate. myText is the long text that wraps.

Let's assume you are using a UILabel to display the text in the UITableViewCell. You can calculate the size of the table cell by using the code below:

-(CGSize) GetSizeOfText: (NSString *) text {
  return [text sizeWithFont:[UIFont systemFontOfSize:17.0
                                                     constrainedToSize:CGSizeMake(220.f, 50.0f)]];
}

Use the above functiona to calculate the frame for the table view cell and use it to initialize the cell

Hope it helps,

Thanks,
Javid

What is the 'f' character for in CGSizeMake?

[javid.alimohideen]

It just says it's a float.

This technique was very helpful, as I struggled with the same problem.

What technique can one use to make hyperlinks click-able in this UILabel view?

Hi,
I have implemented the same method to display text in the UITableView.
My issue is the contents of all the rows of th table view are different.
So can i have labels of varying sizes in UITableViewCell?


or can I use UIView instead of lable in UITableViewCell? so that i can have scroll bars to display data.
