MCSelectorView

Horizontal selector where values can be chosen by either scrolling or tapping. Can be thought asa customized version of the UIPickerView. Here's a screenshot from the sample project:

Installation

Add files in the the 'Classes' folder to your project.

Usage

MCSelectorView was designed to take advantage of an existing element laid out in the Interface Builder or created by some other means. Below is the typical scenario:

1. Design an element in the Inteface Builder. Sample project uses a UILabel, but it can be any kind of UIView or a UIView subclass;

2. Initialize selector, add it to a superview and present it:

    #import "MCSelectorView.h"
    
    ...
    
    _selectorView = [[MCSelectorView alloc] init];
    _selectorView.dataSource = self;
    _selectorView.delegate = self;
    [self.view addSubview:_selectorView];
    [_selectorView present];
   

3. Implement the MCSelectorViewDataSource methods; here's the code from the sample project:

    - (CGRect)optionRectForSelectorView:(MCSelectorView *)view
    {
        return _sampleLabel.frame;
    }
    
    - (NSArray *)optionViewsForSelectorView:(MCSelectorView *)view
    {
        NSArray * optionTitles = @[@"One", @"Two", @"Three", @"Four", @"Five"];
        NSMutableArray * options = [NSMutableArray array];
        
        [optionTitles enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {
            UILabel * label = [self copyLabel];
            label.text = obj;
            [options addObject:label];
        }];
        
        return options;
    }
   

4. Implement the selectorView:didSelectOptionAtIndex: methods of the MCSelectorViewDelegate protocol:

    - (void)selectorView:(MCSelectorView *)selectorView didSelectOptionAtIndex:(NSUInteger)index
    {
        // Do something useful with the index
    }
   

5. Optionally, implement other available methods to decorate the selector view or change it's behavior; check the MCSelectorView.h file for possible options.
