Pod 安装

HCRotaryWheel 通过 CocoaPods 获得。要安装它，只需在 Podfile 中添加以下行

use_frameworks!

pod 'HCRotaryWheel', '~> 0.1.3' 

注意

添加 use_frameworks! 允许 Cocoapods 解析 IBDesignable 元素

手动安装

1. 克隆项目
2. 在 Xcode 的示例项目中构建
3. 将控件文件夹拖入您的项目
4. 在 Identity 检查器中输入类

在 Attributes 检查器中编辑

如何使用 objective-c

在 ViewController.h 中将 HCRotaryWheelView 拖成 IBOutlet 并添加 RotaryProtocol 以调用 Delegate 方法

#import "HCRotaryWheel.h"

@interface ViewController : UIViewController <RotaryProtocol>

@property (weak, nonatomic) IBOutlet UILabel *textLabel;
@property (weak, nonatomic) IBOutlet HCRotaryWheelView *rotaryWheelView;

@end

In ViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];
    //set view controller as delegate to Rotary Wheel
    self.rotaryWheelView.delegate = self;
    //set initial Text for a label or other content
    self.textLabel.text = @"Bear";
}

    // built in HCRotaryWheel Delegate Method
- (void) wheelDidChangeValue:(int)currentSector {
    // change any text when wheel rotates, is tapped or dragged
    self.textLabel.text = [self getDescriptionText:currentSector];
}

- (NSString *) getDescriptionText:(int)newValue {
    NSString *text = @"";
        switch(newValue) {
            case 0:
                text = @"Bear";
                break;
            case 1:
                text = @"Monkey";
                break;
            case 2:
                text = @"Dog";
                break;
            case 3:
                text = @"Ghost";
                break;
            case 4:
                text = @"Peace";
                break;
            case 5:
                text = @"Alien";
                break;
            default:
                break;
        }
    return text;
}

如何使用 Swift

import UIKit
import HCRotaryWheel

class ViewController: UIViewController, RotaryProtocol {


    @IBOutlet weak var textField: UITextField!
    @IBOutlet weak var hcview: HCRotaryWheel!

    override func viewDidLoad() {
        super.viewDidLoad()
        self.hcview.delegate = self
        self.textField.text = "Bear"
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    func wheelDidChangeValue(currentSector: Int32) {
        self.textField.text = self.getDescriptionText(currentSector);
    }

    func getDescriptionText(newValue :Int32) -> String
    {
        switch newValue {
        case 0:
            return "Bear"
        case 1:
            return "Monkey"
        case 2:
            return "Dog"
        case 3:
            return "Ghost"
        case 4:
            return "Peace"
        case 5:
            return "Alien"
        default:
            return "Bear"
        }
    }
