SVSegmentedControl

SVSegmentedControl is a customizable UIControl class that mimics UISegmentedControl but that looks like an UISwitch.

Installation

From CocoaPods

Add pod 'SVSegmentedControl' to your Podfile or pod 'SVSegmentedControl', :head if you're feeling adventurous.

Manually

Important note if your project doesn't use ARC: you must add the -fobjc-arc compiler flag to SVSegmentedControl.m and SVSegmentedThumb.m in Target Settings > Build Phases > Compile Sources.

• Drag the SVSegmentedControl/SVSegmentedControl folder into your project.
• Add the QuartzCore framework to your project.

Usage

(see sample Xcode project in /Demo)

In its simplest form, this is how you create an SVSegmentedControl instance:

segmentedControl = [[SVSegmentedControl alloc] initWithSectionTitles:[NSArray arrayWithObjects:@"Section 1", @"Section 2", nil]];
segmentedControl.changeHandler = ^(NSUInteger newIndex) {
    // respond to index change
};

[self.view addSubview:segmentedControl];

You can position it using either its frame or center property:

Customization

SVSegmentedControl can be customized with the following properties:

@property (nonatomic, strong) NSArray *sectionTitles;
@property (nonatomic, strong) NSArray *sectionImages;

@property (nonatomic, readwrite) BOOL animateToInitialSelection; // default is NO
@property (nonatomic, readwrite) BOOL crossFadeLabelsOnDrag; // default is NO

@property (nonatomic, readwrite) BOOL mustSlideToChange; // default is NO - To make the control difficult to accidentally change, force the user to slide it
@property (nonatomic, readwrite) CGFloat minimumOverlapToChange; // default is 0.66 - Only snap to a new segment if the thumb overlaps it by this fraction
@property (nonatomic, readwrite) UIEdgeInsets touchTargetMargins; // default is UIEdgeInsetsMake(0, 0, 0, 0) - Enlarge touch target of control

@property (nonatomic, strong) UIColor *backgroundTintColor; // default is [UIColor colorWithWhite:0.1 alpha:1]
@property (nonatomic, retain) UIImage *backgroundImage; // default is nil

@property (nonatomic, readwrite) CGFloat height; // default is 32.0
@property (nonatomic, readwrite) UIEdgeInsets thumbEdgeInset; // default is UIEdgeInsetsMake(2, 2, 3, 2)
@property (nonatomic, readwrite) UIEdgeInsets titleEdgeInsets; // default is UIEdgeInsetsMake(0, 10, 0, 10)
@property (nonatomic, readwrite) CGFloat cornerRadius; // default is 4.0

@property (nonatomic, retain) UIFont *font; // default is [UIFont boldSystemFontOfSize:15]
@property (nonatomic, retain) UIColor *textColor; // default is [UIColor grayColor];
@property (nonatomic, strong) UIColor *innerShadowColor; // default is [UIColor colorWithWhite:0 alpha:0.8]
@property (nonatomic, retain) UIColor *textShadowColor;  // default is [UIColor blackColor]
@property (nonatomic, readwrite) CGSize textShadowOffset;  // default is CGSizeMake(0, -1)

Its thumb (SVSegmentedThumb) can be customized as well:

@property (nonatomic, retain) UIImage *backgroundImage; // default is nil;
@property (nonatomic, retain) UIImage *highlightedBackgroundImage; // default is nil;

@property (nonatomic, retain) UIColor *tintColor; // default is [UIColor grayColor]
@property (nonatomic, assign) UIColor *textColor; // default is [UIColor whiteColor]
@property (nonatomic, assign) UIColor *textShadowColor; // default is [UIColor blackColor]
@property (nonatomic, readwrite) CGSize textShadowOffset; // default is CGSizeMake(0, -1)
@property (nonatomic, readwrite) BOOL shouldCastShadow; // default is YES (NO when backgroundImage is set)
@property (nonatomic, assign) CGFloat gradientIntensity; // default is 0.15

To customize the thumb's appearance, you'll have to set the properties through SVSegmentedControl's thumb property. For instance, setting the thumb's tintColor is done with:

segmentedControl.thumb.tintColor = someColor;

Responding to value changes

You can respond to value changes using a block handler:

segmentedControl.changeHandler = ^(NSUInteger newIndex) {
    // respond to index change
};

If you haven't fallen in love with blocks yet, you can still use the classic UIControl method:

[mySegmentedControl addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];

Providing an action method ending with a semicolon, the sender object is therefore made accessible:

- (void)segmentedControlChangedValue:(SVSegmentedControl*)segmentedControl {
	NSLog(@"segmentedControl did select index %i", segmentedControl.selectedIndex);
}
