Multiple lines of text in UILabel

Question

Is there a way to have multiple lines of text in UILabel like in the UITextView or should I use the second one instead?

Answer 1

You can do that via the Storyboard too:

1. Select the Label on the view controller
2. In the Attribute Inspector, increase the value of the Line option (Press Alt+Cmd+4 to show Attributes Inspector)
3. Double click the Label in the view controller and write or paste your text
4. Resize the Label and/or increase the font size so that the whole text could be shown

Answer 2

You can use \r to go to next line while filling up the UILabel using NSString.

UILabel * label;


label.text = [NSString stringWithFormat:@"%@ \r %@",@"first line",@"seconcd line"];

Answer 3

These things helped me

Change these properties of UILabel

label.numberOfLines = 0;
label.adjustsFontSizeToFitWidth = NO;
label.lineBreakMode = NSLineBreakByWordWrapping;

And while giving input String use \n to display different words in different lines.

Example :

 NSString *message = @"This \n is \n a demo \n message for \n stackoverflow" ;

Answer 4

I found a solution.

One just has to add the following code:

// Swift
textLabel.lineBreakMode = .ByWordWrapping // or NSLineBreakMode.ByWordWrapping
textLabel.numberOfLines = 0 

// For Swift >= 3
textLabel.lineBreakMode = .byWordWrapping // notice the 'b' instead of 'B'
textLabel.numberOfLines = 0

// Objective-C
textLabel.lineBreakMode = NSLineBreakByWordWrapping;
textLabel.numberOfLines = 0;

// C# (Xamarin.iOS)
textLabel.LineBreakMode = UILineBreakMode.WordWrap;
textLabel.Lines = 0;  

Restored old answer (for reference and devs willing to support iOS below 6.0):

textLabel.lineBreakMode = UILineBreakModeWordWrap;
textLabel.numberOfLines = 0;

On the side: both enum values yield to 0 anyway.

Use story borad : select the label to set number of lines to zero......Or Refer this

textLabel.lineBreakMode = UILineBreakModeWordWrap;
textLabel.numberOfLines = 0;

The solution above does't work in my case. I'm doing like this:

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    // ...

    CGSize size = [str sizeWithFont:[UIFont fontWithName:@"Georgia-Bold" size:18.0] constrainedToSize:CGSizeMake(240.0, 480.0) lineBreakMode:UILineBreakModeWordWrap];
    return size.height + 20;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

    if (cell == nil)
    {
        // ...
        cell.textLabel.lineBreakMode = UILineBreakModeWordWrap;
        cell.textLabel.numberOfLines = 0;
        cell.textLabel.font = [UIFont fontWithName:@"Georgia-Bold" size:18.0];
    }

    // ...

    UILabel *textLabel = [cell textLabel];
    CGSize size = [text sizeWithFont:[UIFont fontWithName:@"Georgia-Bold" size:18.0]
                                        constrainedToSize:CGSizeMake(240.0, 480.0)
                                            lineBreakMode:UILineBreakModeWordWrap];

    cell.textLabel.frame = CGRectMake(0, 0, size.width + 20, size.height + 20);

    //...
}
