SlotLabel is an animated label that is heavily inspired by casino slots. It was designed as a drop-in replacement for a UILabel. The interface provides customization properties and animation methods. Animating the label to a string is a dead simple, and can be customized to fit many different use cases.

• A smooth easy to use drop in replacement for a UILabel
• Lots of customization options
• IBDesignable and IBInspectable properties
• 100% documentation coverage

SlotLabel is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "SlotLabel"

Now you can add to your project with

#import <SlotLabel/SlotLabel.h>

You can clone the repo with git:

git clone https://github.com/pinnrepo/SlotLabel.git

then simply add the files to your project, and use a local import header

#import "SlotLabel.h"

Heres a quick run down of all configurable properties and methods

- (void)setText:(NSString*)text;
- (void)animateToString:(NSString*)string;

Simply drag a UIView reference onto your storyboard where you would like it to go. Then set your custom class to SlotLabel and your set. If you would like you can then configure some of the IBInspectable properties via the storyboard attributes editor (or do it in code!). Next you will want to create an IBOutlet for your SlotLabel instance.

Now in your view controller you can start animating:

[self.slotLabel animateToString:@"hello world"];

Here your just gonna do a frame init, configure, add the subview and your good to go!

SlotLabel *slotLabel = [[SlotLabel alloc] initWithFrame:CGRectMake(100,100,200,200)];
slotLabel.animationSpeed = 2.0f;
[self.view addSubview:slotLabel];
[slotLabel animateToString:@"programmatically"];

Running the example app is easy and helpful to see how SlotLabel was meant to work.

1. Clone the repository - git clone https://github.com/pinnrepo/SlotLabel.h
2. Open the workspace - open Example/SlotLabel.xcworkspace
3. Compile and run for simulator or device

You can check out the full reference documentation here.

SlotLabel is an effective UIScrollView hack, the basic magic works by positioning UILabels vertically within the UIScrollView, then to animate to a specific character an offset is calculated to shift content. The SlotCharacter does the heavy lifting as far as animation and custom configuration go. The SlotLabel itself just positions the SlotCharacters horizontally next to each other to behave as a label. The SlotLabel just has to orchestrate the correct values to its child SlotCharacter instances.
