Swift Tool Belt, Part 3: Extending UILabel

These extensions will allow easy access to modify the edge insets on a label the extra padding all around the text. The first extension is pretty simple. It adds a rotation transform to a UILabel. The setter for the rotation converts the degrees into radians and then constructs a transform to rotate the label. The getter is not necessary here, so I just return zero. You could extend this extension to do more than just rotation. Any ability you have with CGAffineTransformsuch as translation or scale, can be done in a similar way. However, you will not see your rotation changes take effect until we change the class of our UILabel to DesignableLabel. See my first post in this series to get an explanation of DesignableLabel. At this point, you should be able to see the label rotated in the storyboard. You may notice clipping on your label text after it is rotated. Unfortunately, Interface Builder does not do a great job of rendering the rotated label, but this will not be the case at runtime. The label will not be clipped when you run your project. This is what the rotated label looks like running on the simulator. You cannot set edge insets on a label easily. In order to accomplish it, you have to draw the text manually. The class override will take care of the drawing, and the extension provides easy access to the edge insets in Interface Builder. I did not come up with this solution. Thanks go to Nikolai Ruhe answering this Stack Overflow question. As I mentioned in my first post in this seriesputting the attribute on an extension can be hit and miss. Change the class name of your label to EdgeInsetLabel. After you change the class for your label, you will see the new attributes that we added in the extension show up in the Attributes inspector. I like this solution and use it on almost every project. Thanks again to Nikolai Ruhe. I hope you find it useful as well.

CocoaPods 0. To integrate ActiveLabel into your project add the following to your Podfile :. When using ActiveLabel, it is recommended to use the customize block: method to customize it. The reason is that ActiveLabel is reacting to each property that you set. So if you set 3 properties, the textContainer is refreshed 3 times. When using customize block:you can group all the customizations on the label, that way ActiveLabel is only going to refresh the textContainer once. Before writing ActiveLabel we've tried a lot of the following alternatives but weren't quite satisfied with the quality level or ease of usage, so we decided to contribute our own solution.

MarqueeLabel is a UILabel subclass adds a scrolling marquee effect when the text of the label outgrows the available width. MarqueeLabel will be maintained in Swift only starting with release 4. But if you're looking for prior version Swift compatibility, you can check the older releases. MarqueeLabel automatically scrolls its text, at either a defined rate points per second or over a duration secondswhenever the length of the label's text exceeds the space available given the label's frame. There are several options for the Marquee type, and the default is Continuous which looks just like what Apple typically uses. There are also several optional features to help with your integration of the scrolling nature of MarqueeLabel:. These lines of code create a MarqueeLabel that will scroll across its content in 8. You can then configure the normal UILabel properties, as well as most of the MarqueeLabel configuration properties, via the Attributes tab of the Utility panel! Check out the MarqueeLabel documentation for more about all the features, including:. Also check out the Extras foldera collection of subclasses, extensions, and modifications for MarqueeLabel to implement various functionality that has been requested or suggested, but not merged into the MarqueeLabel code. However, if you see these warnings when building:. Some workarounds include:. As noted above, MarqueeLabel can sometimes have trouble detecting when the scroll animation should start when used in UITableViews and UICollectionViews - although recent reviews have improved this. Even when the cell is eventually placed onscreen as the user scrolls, due to timing it's possible that the animation will not fire. I suggest holding scrolling or labelizing the labels while the user scrolls. See the table view example in the demo! MarqueeLabel is based on Core Animation, which does cause some problems when views appear and disappear and the repeating animation is stopped by iOS and does not automatically restart. Specifically, the class method restartLabelsOfController: should be called by your view controller which passes in self for the controller parameter when it is revealed or about to be revealed. Keep in mind that presenting a modal view controller can pause repeating UIView animations in the controller that is being covered! Skip to content.
