DVSwitch

Customizable control based on UISwitch and UISegmentedControl written in Objective-C

DVSwitch was inspired by UISwitch and UISegmentedControl. The goals of this code are:

Easily customizable control with nice animations
Supporting pan or swipe interactions
Requires very little setup - images are not needed
Beautiful font color inversion effect - label color changes per pixel:
Automatic adjustment based on number of items

Slider is halfway from one item to another, notice per pixel text color change

Usage

DVSwitch *switcher = [[DVSwitch alloc] initWithStringsArray:@[@"First", @"Second"]];
switcher.frame = CGRectMake(20, 60, self.view.frame.size.width - 40, 34);
[self.view addSubview:switcher];
[switcher setPressedHandler:^(NSUInteger index) {
    
    NSLog(@"Did switch to index: %lu", (unsigned long)index);
    
}];

Customizable properties:

UIColor *backgroundColor - color of the controls background
UIColor *sliderColor - color of slider
UIColor *labelTextColorInsideSlider - color of text when slider hovers over it
UIColor *labelTextColorOutsideSlider - color of text when outside of slider
UIFont *font - font used in control
CGFloat cornerRadius - corner radius of control and corner radius of slider
CGFLoat sliderOffset - pixel offset in points between the slider and the edge of control

When the user taps or slides the control, handler block is getting called with the index of element which was triggered. To set it use the following method:
- (void)setPressedHandler:(void (^)(NSUInteger index))handler;

Source code contains example project with few different types of switch.

Requirements:

iOS 7.0 and Xcode 6.0

The control might work on earlier versions, but this was not tested.
