赶时髦用Swift也写了一遍：JingRound-Swift-Branch
rewritten from Objective-C to Swift...
仿jing.fm的音乐播放视图，支持旋转和自定义参数。
Imitation jing.fm music playing view, support rotation and custom parameters.
可以在Storybord、Xib直接拖个View然后更改其类为JingRoundView，设置基本属性即可:
You can Drag and Drop a UIView in Storybord or Xib,and then change its class JingRoundView, set the basic parameter:
//设置代理，获取回调事件
self.roundView.delegate = self;
//设置中间的图像
self.roundView.roundImage = [UIImage imageNamed:@"girl"];
//设置转圈的速度
self.roundView.rotationSpeed = 3.0;
暂停与继续 (resume and pause):
[self.roundView resume];
[self.roundView pause];
当点击中间圆盘的时候会触发暂停、播放事件，当然有一个协议：JingRoundViewDelegate：
When you touch in the middle of the disc when it will trigger the pause, play events, of course, there is a delegate JingRoundViewDelegate:
-(void)playStatuUpdate:(BOOL)playState
{
NSLog(@"%@...", playState ? @"播放": @"暂停了");
}
使用的时候需要引入一下这两个库：
Of course, you need to import two framework:
#import <QuartzCore/QuartzCore.h>
#import <CoreGraphics/CoreGraphics.h>
