我正在像这样添加阴影。
vwVertical=[[UIView alloc] init];
[vwVertical setBackgroundColor:[UIColor whiteColor]];
vwVertical.translatesAutoresizingMaskIntoConstraints = NO;
vwVertical.layer.shadowColor=[UIColor colorWithRed:32/255 green:59/255 blue:90/255 alpha:1.0].CGColor;
vwVertical.layer.shadowOffset=CGSizeMake(5, 0);
vwVertical.layer.shadowOpacity=0.12;
vwVertical.layer.shadowRadius=6.5;
[vwBlock addSubview:vwVertical];
但这是添加阴影 3 边。我怎样才能添加到右侧。 请帮我。 谢谢
最佳答案
您需要做的就是将 View 的边界插入top
- left
- bottom
,并使用shadow path .
vwVertical=[[UIView alloc] init];
// Create edge insets
UIEdgeInsets contentInsets = UIEdgeInsetsMake(0, 10, 0, 0);
// Create rect with inset and view's bounds
CGRect shadowPathOnlyIncludingRight = UIEdgeInsetsInsetRect(vwVertical.bounds, contentInsets);
// Apply it on the layer's shadowPath property
vwVertical.layer.shadowPath = [UIBezierPath bezierPathWithRect:shadowPathOnlyIncludingRight].CGPath;
[vwVertical setBackgroundColor:[UIColor whiteColor]];
vwVertical.translatesAutoresizingMaskIntoConstraints = NO;
vwVertical.layer.shadowColor=[UIColor colorWithRed:32/255 green:59/255 blue:90/255 alpha:1.0].CGColor;
vwVertical.layer.shadowOffset=CGSizeMake(5, 0);
vwVertical.layer.shadowOpacity=0.12;
vwVertical.layer.shadowRadius=6.5;
关于ios - 如何只为右侧添加阴影?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/41415231/
