beichenglangzi/tosegmentedcontrol

A segmented control in the style of iOS 13 compatible with previous versions of iOS.

TOSegmentedControl

As part of the visual improvements featured in iOS 13, UISegmentedControl was completely redesigned, featuring a much rounder, cleaner, and slightly more skeuomorphic appearance.

TOSegmentedControl is a subclass of of UIControl that completely re-implements the look and feel of the new UISegmentedControl component, allowing developers to adopt its look even in previous versions of iOS they support.

Features

• Recreates the new look of UISegmentedControl, making it available on previous versions of iOS.
• Supports both text and images as segment types.
• Support for @IBDesignable and @IBInspectable.
• Configurable to dynamically add or remove items after its creation.
• Written in Objective-C, but provides full compatibility with Swift.
• Provides both a block, or UIControlEvents to receive when the control is tapped.
• Light and dark mode support for iOS 13.
• A reversible mode where tapping the same item twice flips its direction.

Sample Code

TOSegmentedControl has been written to follow the interface of UISegmentedControl as closely as possible. This should make it very intuitive to work with.

Swift

In Swift, the class is renamed to SegmentedControl. Creating a new instance is very similar to UISegmentedControl.

// Create a new instance
let segmentedControl = SegmentedControl(items: ["First", "Second", "Third"])

// Add a closure that will be called each time the selected segment changes
segmentedControlsegmentTappedHandler = { segmentIndex, reversed in
   print("Segment \(segmentIndex) was tapped!")
}

// Add a new item to the end
segmentedControl.addSegment(withTitle: "Fourth")

// Insert a new item at the beginning
segmentedControl.insertSegment(withTitle: "Zero", at: 0)

// Remove all segments
segmentedControl.removeAllSegments()

Objective-C

NSArray *items = @[@"First", @"Second", @"Third"];

// Create a new instance
TOSegmentedControl *segmentedControl = [[TOSegmentedControl alloc] initWithItems:items]];

// Add a block that will be called each time the selected segment changes
segmentedControl.segmentTappedHandler = ^(NSInteger index, BOOL reversed) {
    NSLog(@"Segment %d was tapped!", index);
};

// Add a new item to the end
[segmentedControl addSegmentWithTitle:@"Fourth"];

// Insert a new item at the beginning
[segmentedControl insertSegmentWithTitle:@"Zero" atIndex:0];

// Remove all segments
[segmentedControl removeAllSegments];
