A Vertical Segmented Control View for iOS

Requirements

• Xcode 5 or higher
• Apple LLVM compiler
• iOS 7.0 or higher
• ARC

Installation

Manual Installation

All you need to do is drop 'EMVerticalSegmentedControl' files into your project.

Example Usage

Using Interface Builder, just set a designated views class to be of EMVerticalSegmentedControl or manually create with code like so:

    EMVerticalSegmentedControl *control = [[EMVerticalSegmentedControl alloc] initWithFrame:CGRectMake(0, 0, 150, 140)];
        control.sectionTitles = @[@"On", @"Off", @"Maybe", @"Could you repeat?"];
    [self.view addSubview:control];
    control.center = CGPointMake(320 / 2, 568 / 2);

Make sure you set the sectionTitles otherwise you will have a blank segment :)

To listen for segment changes you have two options. The first is the implement the classic Add Target method:

- (void)viewDidLoad {
    ...
    [control addTarget:self action:@selector(segmentDidChange:) forControlEvents:UIControlEventValueChanged];
}

- (void)segmentDidChange:(id)sender {
    NSInteger index = ((EMVerticalSegmentedControl *)sender).selectedSegmentIndex;
    NSLog(@"Value changed selector: %lu", index);
}

You can also add a block object for a callback.

- (void)viewDidLoad {
    [control setIndexChangeBlock:^(NSInteger index) {
        NSLog(@"Value changed in block: %lu", index);
    }];
}

These are not mutually exclusive, and you can use both if you desire.
