iOS7 毛玻璃特效代码 这篇文章主要分享了iOS7 毛玻璃特效代码，非常的实用，做IOS开发的童鞋们不要错过了 原图： 效果图： 实现：首先需要导入Accelerate.framework。然后把两个文件加入到自己的项目中即可。UIImage+ImageEffects.h 复制代码 代码如下: #import @interfaceUIImage(ImageEffects)-(UIImage*)applyLightEffect;-(UIImage*)applyExtraLightEffect;-(UIImage*)applyDarkEffect;-(UIImage*)applyTintEffectWithColor:(UIColor*)tintColor;-(UIImage*)applyBlurWithRadius:(CGFloat)blurRadius tintColor:(UIColor*)tintColor saturationDeltaFactor:(CGFloat)saturationDeltaFactor maskImage:(UIImage*)maskImage;@end UIImage+ImageEffects.m 复制代码 代码如下: #import UIImage+ImageEffects.h#import #import @implementationUIImage(ImageEffects)-(UIImage*)applyLightEffect{UIColor*tintColor =[UIColor colorWithWhite:1.0 alpha:0.3];return[self applyBlurWithRadius:30 tintColor:tintColor saturationDeltaFactor:1.8 maskImage:nil];}-(UIImage*)applyExtraLightEffect{UIColor*tintColor =[UIColor colorWithWhite:0.97 alpha:0.82];return[self applyBlurWithRadius:20 tintColor:tintColor saturationDeltaFactor:1.8 maskImage:nil];}-(UIImage*)applyDarkEffect{UIColor*tintColor =[UIColor colorWithWhite:0.11 alpha:0.73];return[self applyBlurWithRadius:20 tintColor:tintColor saturationDeltaFactor:1.8 maskImage:nil];}-(UIImage*)applyTintEffectWithColor:(UIColor*)tintColor{constCGFloatEffectColorAlpha=0.6;UIColor*effectColor = tintColor;int componentCount =CGColorGetNumberOfComponents(tintColor.CGColor);if(componentCount ==2){CGFloat b;if([tintColor getWhite:b alpha:NULL]){effectColor =[UIColor colorWithWhite:b alpha:EffectColorAlpha];}}else{CGFloat r, g, b;if([tintColor getRed:r green:g blue:b alpha:NULL]){effectColor =[UIColor colorWithRed:r green:g blue:b alpha:EffectColorAlpha];}}return[self applyBlurWithRadius:10 tintColor:effectColor saturationDeltaFactor:-1.0 maskImage:nil];}-(UIImage*)applyBlurWithRadius:(CGFloat)blurRadius tintColor:(UIColor*)tintColor saturationDeltaFactor:(CGFloat)saturationDeltaFactor maskImage:(UIImage*)maskImage{// Check pre-conditions.if(
