ZYCornerRadius

一句代码，圆角风雨无阻

A Category to make cornerRadius for UIImageView have no Offscreen-Rendered, be more efficiency
避免为UIImageView设置圆角时触发离屏渲染所带来的性能损耗，两种工作方式：Category和UIImageView子类。

##CocoaPods:
```
pod 'ZYCornerRadius', '~> 1.0.2'
```

##性能对比:
测试设备6P，屏幕中有40张尺寸为20*20的小图片，使用masksToBounds切角处理时帧率大大下降至20+，使用ZYCornerRadius时帧率保持在57+，性能接近0损耗。

##Usage:

导入头文件
```objc
#import "UIImageView+CornerRadius.h"
```
创建圆角半径为6的UIImageView(两种种方式)：
```objc
//1
UIImageView *imageView = [[UIImageView alloc] initWithCornerRadiusAdvance:6.0f rectCornerType:UIRectCornerAllCorners];

//2
UIImageView *imageView = [[UIImageView alloc] init];
[imageView zy_cornerRadiusAdvance:6.0f rectCornerType:UIRectCornerAllCorners];
```
创建圆形的UIImageView(两种方式)：
```objc
//1
UIImageView *imageView = [[UIImageView alloc] initWithRoundingRectImageView];

//2
UIImageView *imageView = [[UIImageView alloc] init];
[imageView zy_cornerRadiusRoundingRect];
```
可为UIImageView的图片附加边框：
```objc
[imageView zy_attachBorderWidth:1.f color:[UIColor redColor]];
```
按你的需要完成配置后，任何时候对UIImageView setImage，效果都会生效
```objc
//anytime
imageView.image = [UIImage imageNamed:@"mac_dog"];
```
