名为＆＃39; setCornerRadius的多种方法：＆＃39;发现结果不匹配，参数类型或属性

Question

当我尝试设置片段的角半径

时出现此错误

[[self.daysSegment.subviews objectAtIndex:cnt] setCornerRadius:0];

  

多个名为＆＃39; setCornerRadius的方法：＆＃39;发现结果不匹配，参数类型或属性

谢谢

Answer 1

试试这个 -

[[(UIView*)[self.daysSegment.subviews objectAtIndex:cnt] layer] setCornerRadius:0];

修改

我建议你打破上面的代码。它将使调试更容易。

UIView  *view  = [self.daysSegment.subviews objectAtIndex:cnt];
CALayer *layer = [view layer];
layer.cornerRadius = 0.0;

Answer 2

更改为

[[self.daysSegment.subviews objectAtIndex:cnt].layer setCornerRadius:0];

cornerRadius适用于视图层

Answer 3

((UIView*)[self.daysSegment.subviews objectAtIndex:cnt]).layer.cornerRadius = 0
