ExpandableLabel

ExpandableLabel is a simple UILabel subclass that shows a tappable link if the content doesn't fit the specified number of lines. If touched, the label will expand to show the entire content.

Maintenance

This project is passively maintained. Pull Requests are welcome, will be reviewed, merged and released as new CocoaPod version as long as they don't break things. Nevertheless we don't have the resources to actively continue development, answer issues or give support for integration.

Installation

CocoaPods

Add this to your Podfile:

pod "ExpandableLabel"

Carthage

Add this to your Cartfile:

github "apploft/ExpandableLabel"

Run carthage to build the framework and drag the built ExpandableLabel.framework into your Xcode project.

Usage

Using ExpandableLabel is very simple. In your storyboard, set the custom class of your UILabel to ExpandableLabel and set the desired number of lines (for the collapsed state):

Note: In Carthage, set Module to ExpandableLabel.

expandableLabel.numberOfLines = 3

Apart from that, one can modify the following settings:

delegate

Set a delegate to get notified in case the link has been touched.

collapsed

Set true if the label should be collapsed or false for expanded.

expandableLabel.collapsed = true
collapsedAttributedLink

Set the link name (and attributes) that is shown when collapsed.

expandableLabel.collapsedAttributedLink = NSAttributedString(string: "Read More")
expandedAttributedLink

Set the link name (and attributes) that is shown when expanded. It is optional and can be nil.

expandableLabel.expandedAttributedLink = NSAttributedString(string: "Read Less")
setLessLinkWith(lessLink: String, attributes: [String: AnyObject], position: NSTextAlignment?)

Setter for expandedAttributedLink with caption, String attributes and optional horizontal alignment as NSTextAlignment. If the parameter position is nil, the collapse link will be inserted at the end of the text.

expandableLabel.setLessLinkWith(lessLink: "Close", attributes: [NSForegroundColorAttributeName:UIColor.red], position: nil)

ellipsis

Set the ellipsis that appears just after the text and before the link.

expandableLabel.ellipsis = NSAttributedString(string: "...")
