一个iOS圆形进度条开源库，你可以定制它的大小、进度条背景色和前景色以及进度条的宽度。

Latest Update 最新更新内容

Now you can drag the progress to precise location to where it should to play.
现在支持拖拽进度以便精确控制播放进度。

Installation 安装方法

1.Add AVFoundation.framework into your project.
1.在工程项目中加入AVFoundation.framework & QuartzCore.framework框架。

2.Drop "CircularProgressView.h" & "CircularProgressView.m" into your project.
2.将“CircularProgressView.h”和“CircularProgressView.m”文件拖拽至工程目录。

Usage 使用方法

First in your ViewController import the header file CircularProgressView.h, and create a CircularProgressView property to keep a reference:
首先在你的ViewController中导入CircularProgressView.h头文件并且新建一个圆形进度条属性来作为一个引用:
@property (nonatomic) CircularProgressView *circularProgressView;
Then you can create circular progress view by Interface Builder or by code.
之后你可以通过Interface Builder方式或者写代码的方式新建一个圆形进度条。

1.To create by using Interface Builder:
1.通过Interface Builder建立:
Drop a UIView object into your xib or storyboard file, modify its class name to CircularProgressView:
在你的Xib或者故事版文件中放下一个UIView对象，修改它的类名为CircularProgressView:

then define circular progress view propertys in viewDidLoad method like this:
之后如下方式在viewDidLoad方法中定义圆形进度条的属性:

    self.circularProgressView.backColor = [UIColor colorWithRed:236.0 / 255.0
                                                          green:236.0 / 255.0
                                                           blue:236.0 / 255.0
                                                          alpha:1.0];
    self.circularProgressView.progressColor = [UIColor colorWithRed:82.0 / 255.0
                                                              green:135.0 / 255.0
                                                               blue:237.0 / 255.0
                                                              alpha:1.0];
    self.circularProgressView.audioURL = [[NSBundle mainBundle] URLForResource:@"我的歌声里" withExtension:@"mp3"];

    self.circularProgressView.lineWidth = 20;

    //set CircularProgressView delegate
    self.circularProgressView.delegate = self;

2.To create the object using codes like this:
2.用写代码的方式建立对象:

    //get a audio path
    NSURL *audioURL = [[NSBundle mainBundle] URLForResource:@"我的歌声里" withExtension:@"mp3"];
    //set back color & progress color
    UIColor *backColor = [UIColor colorWithRed:236.0/255.0 
	       								 green:236.0/255.0 
			     						  blue:236.0/255.0 
				    					 alpha:1.0];
    UIColor *progressColor = [UIColor colorWithRed:82.0/255.0 
									       	green:135.0/255.0 
										     blue:237.0/255.0 
										    alpha:1.0];
    
    //alloc CircularProgressView instance
    self.circularProgressView = [[CircularProgressView alloc] initWithFrame:CGRectMake(41, 57, 238, 238) 
															  backColor:backColor 
														  progressColor:progressColor 
															  lineWidth:30 
															  audioURL:audioURL];
    //set CircularProgressView delegate
    self.circularProgressView.delegate = self;
    //add CircularProgressView
    [self.view addSubview:self.circularProgressView];

API 提供接口

You can play,pause & stop audio by below methods declared in the header file CircularProgressView.h
你可以通过如下方法播放、暂停或者停止音频，这些方法声明在CircularProgressView.h头文件中:

- (void)play;
- (void)pause;
- (void)stop;
