我想在tableviewcell上添加4个部分的阴影(1个tableView和4个tableViewCell),其中我想在3个边(左,右,下)添加阴影的最后一个单元格,但是除了我想要的最后一个单元格之外的另一个单元格在2侧(左,右)添加阴影。我用单例和扩展名UIView编写这段代码。 这是最后一个单元格:
func dropShadowAtBottom() {
self.layer.masksToBounds = false
self.layer.shadowColor = UIColor.black.cgColor
self.layer.shadowOpacity = 0.2
self.layer.opacity = 0.3
self.layer.shadowOffset = CGSize(width: 0, height: 2)
self.layer.shadowRadius = 2
self.clipsToBounds = false
}
这是除了最后一个单元格之外的另一个单元格:
func dropShadowAtLeftAndRight() {
self.layer.masksToBounds = false
self.layer.shadowColor = UIColor.black.cgColor
self.layer.shadowOpacity = 0.5
self.layer.shadowOffset = CGSize(width: 0, height: 0)
self.layer.shadowRadius = 2
let shadowRect: CGRect = self.layer.bounds.insetBy(dx: 0, dy: 4); // inset top/bottom
self.layer.shadowPath = UIBezierPath(rect: shadowRect).cgPath
self.layer.rasterizationScale = UIScreen.main.scale
self.layer.shouldRasterize = true
}
我在cellForRow中调用此代码:
if(indexPath.row == currentOrderHistory.listOrderItems.count - 1){
cell.bodyView.dropShadowAtBottomOnly()
}else{
cell.bodyView.dropShadowAtLeftAndRight()
}
return cell
现在这段代码工作但仍然不完美。细胞之间有空白区域。
我只想让它们连接起来。

您是否尝试从IB中删除分隔符?
将分隔符设置为无
或其他方式,将分隔符颜色设置为半透明
import sys
ALPHABET= ['a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z',' ']
def main(plaintext, key):
cypher = generate_cypher(key)
plaintext = sys.argv[1]
e_code = encode_message(plaintext, cypher)
mes s= decode_message(e_code, cypher)
def generate_cypher(key):
cipher = []
for i in range(len(ALPHABET)):
cipher.append(ALPHABET[i+key%27])
print(cipher)
return(cipher)
def encode_message(plaintext,cipher):
key = int(sys.argv[2])
en_code=''
for c in plaintext:
if c in cipher:
en_code+=cipher[(cipher.index(c)+key)%(len(cipher))]
print("Encoded: ", en_code)
return en_code
def decode_message(e_code,cipher):
key = int(sys.argv[2])
message = []
for i in range(len(e_code)):
message.append(cipher[i-key%27])
mess=''.join(message)
print("Decoded: ", mess)
return mess

我认为您在此行的dropShadowAtLeftAndRight()
中遇到了问题
let shadowRect: CGRect = self.layer.bounds.insetBy(dx: 0, dy: 4);
在我的情况下,它会返回rect
看起来像(0.0, 4.0, 375.0, 36.0)
。在顶部4px是白色空间,底部也是4px白色空间
所以你的左右阴影将从4开始,高度为36。
要解决此问题,您需要像这样设置
let shadowRect: CGRect = self.layer.bounds.insetBy(dx: 0, dy: 0);
