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


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


(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];
[segmentedControl release];

You’re highly encouraged to position it using its center property:

segmentedControl.center = CGPointMake(160, 70);


SVSegmentedControl can be customized with the following properties:

@property (nonatomic, readwrite) NSUInteger selectedIndex; // default is 0
@property (nonatomic, readwrite) BOOL animateToInitialSelection; // default is NO
@property (nonatomic, readwrite) BOOL crossFadeLabelsOnDrag; // default is NO

@property (nonatomic, retain) UIColor *tintColor; // default is [UIColor grayColor]
@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, 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)

Note: 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);

Automatic Reference Counting (ARC) support

Maintaining an official ARC branch has proven to be too much work, often leading to confusion since the ARC branch is always a few commits behind. If you’d like to use SVSegmentedControl in your ARC-enabled project, you’ll have to add the -fno-objc-arc compiler flag to all of SVSegmentedControl’s files.
