近期在学习动画，为了巩固，写了这一个demo和大家分享 用法很简单：

1.导入头文件

#import "CMuneBar.h"

2.创建

CMuneBar *muneBar = [[CMuneBar alloc] initWithItems:@[@"gallery",@"dropbox",@"camera",@"draw"] size:CGSizeMake(50, 50) type:kMuneBarTypeRadLeft];

3.设置代理

muneBar.delegate = self;

4.添加到视图

[self.view addSubview:muneBar];

在这里我提供了十种样式

typedef NS_OPTIONS(NSUInteger, MuneBarType){ kMuneBarTypeRadLeft = 0,
kMuneBarTypeRadRight,
kMuneBarTypeLineTop,
kMuneBarTypeLineBottom,
kMuneBarTypeLineLeft,
kMuneBarTypeLineRight,
kMuneBarTypeRoundTop,
kMuneBarTypeRoundBottom,
kMuneBarTypeRoundLeft,
kMuneBarTypeRoundRight,
};
