ATCircularProgressView

这是一个为 iOS 设计的非常简单的环形进度视图，您可以在 Storyboard 中或通过代码进行自定义。它轻量且性能卓越 - 使用 CAShapeLayers 进行绘图并使用 CADisplayLink 更新进度。

用法

您可以在代码中创建实例，也可以通过将 UIView 拖动到 Storyboard 并设置子类和模块来创建。

以下是如何设置进度的示例

Swift

progressView.setProgress(value: random, animated: true, duration: 1, completion: nil)

Objective-C

[self.progressView setProgressWithValue:0.5 animated:YES duration:1 completion:nil];

如果您想在进度变化时执行某些工作，例如更新标签，请设置 progressChanged 属性

Swift

 let progressChanged: (CircularProgressView, CGFloat) -> () = { [unowned self]
      (progressView, progress) in
      let value = Int(progress * 100.0)
      self.centralLabel.text = "\(value)%"
}

progressView.progressChanged = progressChanged

Objective-C

   __weak typeof(self) weakSelf = self;
    self.progressView.progressChanged =  ^(CircularProgressView *progressView, CGFloat progress) {
        __strong typeof(self) self = weakSelf;
        self.label.text = [NSString stringWithFormat:@"%ld", (long)progress];
    };

CircularProgressView 可在 Storyboard 中进行设计。您可以设置边界/进度层的宽度和颜色以及进度值。

查看演示项目，进行尝试。

待办事项

• iOS 6+ 支持
• 重构
• 编写测试
• 修复边界/进度层不同宽度下的空格问题
• 设置图片
