iOS7以来,应用界面上的设计很多都采用了毛玻璃效果

苹果也放出了实现毛玻璃的分类

有需要的直接搜索下面的关键字~

UIImage+ImageEffects.h,简单明了,好看好用

#import 
     
      @interface UIImage (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

还有一种就是直接拿NavigationBar的效果自己封装一个视图(跟一个同学聊天的的时候他教我的~)

@interface SlurImageView ()@property (nonatomic, strong) UINavigationBar *slurNavigationbar;@end@implementation SlurImageView- (id)initWithFrame:(CGRect)frame{    self = [super initWithFrame:frame];    if (self) {        // Initialization code                [self setup];            }    return self;}-(void)awakeFromNib{    [self setup];}- (void)setup{    // If we don't clip to bounds the toolbar draws a thin shadow on top    [self setClipsToBounds:YES];        if (!self.slurNavigationbar)    {        UINavigationBar *navigationBar = [[UINavigationBar alloc] initWithFrame:[self bounds]];        self.slurNavigationbar = navigationBar;        [self.layer insertSublayer:self.slurNavigationbar.layer atIndex:0];    }}- (void)layoutSubviews{    [super layoutSubviews];        [self.slurNavigationbar setFrame:[self bounds]];}/*// Only override drawRect: if you perform custom drawing.// An empty implementation adversely affects performance during animation.- (void)drawRect:(CGRect)rect{    // Drawing code}*/@end

iOS8下苹果直接提供了实现毛玻璃效果的API
