How to do multiline UILabel in ios?

Set adjustsFontSizeToFitWidth to NO and numberOfLines to 0.

numberOfLines Docs

This property controls the maximum number of lines to use in order to fit the label’s text into its bounding rectangle. The default value for this property is 1. To remove any maximum limit, and use as many lines as needed, set the value of this property to 0.

If you constrain your text using this property, any text that does not fit within the maximum number of lines and inside the bounding rectangle of the label is truncated using the appropriate line break mode.

When the receiver is resized using the sizeToFit method, resizing takes into account the value stored in this property. For example, if this property is set to 3, the sizeToFit method resizes the receiver so that it is big enough to display three lines of text.

You may additionally want to specify the lineBreakMode unless the default UILineBreakModeWordWrap is suitable for what you want.

Use UILabel properties as below :

textLabel.lineBreakMode = NSLineBreakByWordWrapping;  textLabel.numberOfLines = 0;

Yes, you set the numberOfLines to 0, and the .lineBreakMode to UILineBreakModeWordWrap in code, or the equivalents if your label is defined in IB.
