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。

内存使用对比:

Usage:

导入头文件

#import "UIImageView+CornerRadius.h"

创建圆角半径为6的UIImageView(两种种方式):

//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):

//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:

[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

//anytime 
imageView.image = [UIImage imageNamed:@"mac_dog"];
