今天无意间看到小米手机在充电的时候 home键上的小灯一闪一闪的好像会呼吸，于是联想到了在ios 视图上加上一个这个效果是不是会显得有生命力。。。呵呵呵。。随便写了几行代码

#import <UIKit/UIKit.h>

@interface BreathLight : UIView

@end

#import "breathLight.h"

@implementation breathLight

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code
        [self setupCustomView];
        [self breathe];
    }
    return self;
}

-(void)setupCustomView
{
    self.frame = CGRectMake(0, 0, 10, 10);
    self.backgroundColor = [UIColor redColor];
    self.layer.cornerRadius = self.width/2;
    self.layer.shadowColor = [UIColor redColor].CGColor;
    self.layer.shadowOpacity = 0.5;
    self.layer.shadowRadius = self.width/2;
    self.layer.shouldRasterize = YES;
    
    
}

-(void)breathe
{

    [UIView animateWithDuration:2 animations:^{
        self.alpha = (self.alpha == 1)?0.6:1;

    } completion:^(BOOL finished) {
        [self breathe];
    }];
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
- (void)drawRect:(CGRect)rect
{
    // Drawing code
}
*/

@end
