Question

在我的应用程序中，我需要更改礼服颜色，我使用颜色选择器来做它。对于红色衬衫，我需要应用颜色，它不完全正常工作，并显示一个黑暗的阴影。我们可以改变颜色红色与拾色器颜色兼容？这里是我的代码

imageLayer = [CALayer layer]; 
    NSLog(@"imageLayer %@",imageLayer); 
    NSLog(@"self.layer %@",self.layer); 
    imageLayer.frame = CGRectMake(0, 0, 660, 1000); 
    imageLayer.cornerRadius = 10.0; 
    imageLayer.backgroundColor = [UIColor clearColor].CGColor; 
    //imageLayer.contents = (id) [UIImage imageNamed:@"3.png"].CGImage; 
    imageLayer.masksToBounds = YES; 
    [self.layer addSublayer:imageLayer]; 
    subLayer = [CALayer layer]; 
    subLayer.frame = CGRectMake(0, 0, 660, 1000); 
    subLayer.cornerRadius = 10.0; 
    subLayer.backgroundColor = [UIColor clearColor].CGColor; 
    subLayer.contents = (id) [UIImage imageNamed:@"1.png"].CGImage; 
    [imageLayer addSublayer:subLayer];
