textLabel.lineBreakMode = NSLineBreakByWordWrapping;

But i cant make label height and width as wrap content

Answer 1

So assuming you use Auto Layout, you can always use this line to make the label fit its content horizontally

[textLabel setContentHuggingPriority:UILayoutPriorityRequired
                             forAxis:UILayoutConstraintAxisHorizontal];

If you are not using Auto Layout, try adding this after setting the font, font size and all other details.

[textLabel sizeToFit]

Answer 2

Try adding:

[textLabel sizeToFit];

after:

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

Also, if you are using "Auto" layout, then check your constraints are not conflicting. Make sure if you have not provided "Fixed" width constraint.
