UILabel auto resize on basis of text to be shown

Question

I\'m working on an application, in which I\'m required to autoresize the text area on basis of text to be displayed.

Firstly, I\'m not sure for this either I should use

Answer 1

If you want to resize the UILabel only in height, use this:

@property (nonatomic, weak) IBOutlet UILabel *titleLabel;

CGRect titleLabelBounds = self.titleLabel.bounds;
titleLabelBounds.size.height = CGFLOAT_MAX;
// Change limitedToNumberOfLines to your preferred limit (0 for no limit)
CGRect minimumTextRect = [self.titleLabel textRectForBounds:titleLabelBounds limitedToNumberOfLines:2];

CGFloat titleLabelHeightDelta = minimumTextRect.size.height - self.titleLabel.frame.size.height;
CGRect titleFrame = self.titleLabel.frame;
titleFrame.size.height += titleLabelHeightDelta;
self.titleLabel.frame = titleFrame;

Now you can use titleLabelHeightDelta to layout other views depending on your label size (without using autolayout).
