Hi,

I am adding a label in my custom tableviewcell. But the text is too long to fit in a single line.So i want it to be wrapped on to the next line.

I used lineBreakMode as UILineBreakModeWordWrap and also set the numberOfLines to 0.

But the text was cut off.

My actual text is
This is a sample text for a label

Before setting these properties the output was like
This is a sample text for...

And after setting the properties it comes out to be
This is a sample text for


Actually i cannot increase the width for the label due to my app design, so i have to display it on multiple lines.

Please let me know if i need to set some other properties or change the existing to some other values..

Thanks,
Akshay.

Can you paste in the code block in which you allocate/initialize the label and add it to the view?

Hi wyvwyv,

Here my code snippet that does the thing...

mainText = [self newLabelForMainText:YES setSizeFor:1];
mainText.textAlignment = UITextAlignmentLeft;
[self addSubview:mainText];
[mainText release];


- (UILabel *)newLabelForMainTextBOOL)main setSizeForNSInteger)sizeFor{
...
newLabel = [[UILabel alloc] initWithFrame:CGRectMake(10,2,200,30)];
newLabel.lineBreakMode = UILineBreakModeWordWrap;
newLabel.numberOfLines = 0;
newLabel.opaque = YES;
newLabel.textColor = primaryColor;
newLabel.highlightedTextColor = selectedColor;
newLabel.font = font;
..
return newLabel;
}

Please help me out for this..
Actually the text fits in if i reduce the font size.
But i dont want to do that...

Here is code I use that wraps the text in the label just fine.

labelInstructions.numberOfLines = 0;
labelInstructions.backgroundColor = [UIColor clearColor];
labelInstructions.text = @"..long text string..";
[self.view addSubview:labelInstructions];

If you ask me, the problem is that your label's veritcal height is too small. You set it to 30, which is probably the height of your font (you didn't include your font instantiation, so I don't know for sure). You probably can't fit more than one line of text in that label vertically. Try changing the label height to 60 or 100.

hi wyvwyv,

It was the same what you said... that the label's vertical height was small.. however my font size was 15 but still it was giving problem.
Now i changed the label height to 40 and the wrapped text is shown...

However is it possible that my cell height would be changed according to the height of the text in that cell..
I mean if text fits in a single line then the row size would be for single line, however if the text is wrapped to 2 or 3 lines then the row height is changed accordingly.

The reason i need this is that if i have 3 rows in my table out of which only 1 row has wrapped text of 3 lines then the other two rows have lots of free space which looks very bad...

Thanks...

So these labels are going inside of UITableCellViews? And you want to make the height of the table cell appropriate to the height of the text?

Not simple, but I think it is possible. You'll need to subclass UITableCellView (which I'm guessing you've done).

The table itself should have a delegate with the tableView:heightForRowAtIndexPath method. This method is what you use to set the height for each row.

What you also need is an array of your subclassed UITableCellViews somewhere (which is what you would use to populate the table in the tableView:cellForRowAtIndexPath: method).

The subclassed table cell must have a public member or property that says how much height that cell will want.

You can use the textRectForBounds:limitedToNumberOfLines: of the UILabel to get the drawing rectangle of the label. Use the height component of that size to determine the height required, and pass it back to the table delegate that determines the height of the cell.
