iPhone开发笔记 (7) 用Layer制作圆角button

 制作圆角button的方法很多这里只介绍采用Layer的方法，随让layer效率上实在是不尽如人意，但是效果上绝对没话说。

    下面的代码我是采用imageView加上透明button做的效果。直接修改button的layer我没弄过，不过原理应该差不多。

    先看看效果图

   
[plain] 
UIImageView *imageView1 = [[UIImageView alloc] init]; 
    imageView1.frame = CGRectMake(23.75, 16.6, 75, 75); 
    imageView1.image = [UIImage imageNamed:@"menu1.png"]; 
    imageView1.layer.MasksToBounds = YES;   
    imageView1.layer.cornerRadius = 10.0;  
    imageView1.layer.borderWidth = 2;   
    imageView1.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];  
    imageView1.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1]; 
     
     
    UIImageView *imageView2 = [[UIImageView alloc] init]; 
    imageView2.frame = CGRectMake(122.5, 16.6, 75, 75); 
    imageView2.image = [UIImage imageNamed:@"menu2.png"]; 
    imageView2.layer.MasksToBounds = YES;   
    imageView2.layer.cornerRadius = 10.0;   
    imageView2.layer.borderWidth = 2;   
    imageView2.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];   
    imageView2.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1]; 
     
    UIImageView *imageView3 = [[UIImageView alloc] init]; 
    imageView3.frame = CGRectMake(221.25, 16.6, 75, 75); 
    imageView3.image = [UIImage imageNamed:@"menu3.png"]; 
    imageView3.layer.MasksToBounds = YES;   
    imageView3.layer.cornerRadius = 10.0;   
    imageView3.layer.borderWidth = 2;   
    imageView3.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];   
    imageView3.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1]; 
     
    UIImageView *imageView4 = [[UIImageView alloc] init]; 
    imageView4.frame = CGRectMake(23.75, 118.2, 75, 75); 
    imageView4.image = [UIImage imageNamed:@"menu4.png"]; 
    imageView4.layer.MasksToBounds = YES;   
    imageView4.layer.cornerRadius = 10.0;   
    imageView4.layer.borderWidth = 2;  
    imageView4.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];   
    imageView4.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1]; 
     
    UIImageView *imageView5 = [[UIImageView alloc] init]; 
    imageView5.frame = CGRectMake(122.5, 118.2, 75, 75); 
    imageView5.image = [UIImage imageNamed:@"menu5.png"]; 
    imageView5.layer.MasksToBounds = YES;   
    imageView5.layer.cornerRadius = 10.0;   
    imageView5.layer.borderWidth = 2;  
    imageView5.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];   
    imageView5.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1]; 
     
    UIImageView *imageView6 = [[UIImageView alloc] init]; 
    imageView6.frame = CGRectMake(221.25, 118.2, 75, 75); 
    imageView6.image = [UIImage imageNamed:@"menu6.png"]; 
    imageView6.layer.MasksToBounds = YES;   
    imageView6.layer.cornerRadius = 10.0;   
    imageView6.layer.borderWidth = 2;   
    imageView6.layer.borderColor = [[UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1] CGColor];   
    imageView6.backgroundColor = [UIColor colorWithRed:161/255.0 green:47/255.0 blue:47/255.0 alpha:1];
