推荐答案
取一个标志(Bool 我的意思是),它的初始值将是 false
.现在在单选按钮的选择上将其值设置为 true
.
Take one flag (Bool I mean), It's initial value will be false
. now on radio button's selection set it's value to true
.
现在,更改 numberofSection
方法.它将有条件地返回 1
或 4
.我的意思是如果你的标志是 true
然后返回 4
否则 1
!就这样!
Now, change numberofSection
method. It will conditionally returns 1
or 4
. I mean if your flag was true
then return 4
else 1
! that's it!
