I have a model as follows:
class Expertise:NSObject{
var expertise:String = ""
var isSelevted:Bool = false
}
I want the array of the selected expertise.
I tried:
Obj.filter{$0.isSelected == true}.first.expertise
but the above line didn't worked.
要获取数组中每个选定对象的专业知识值,请使用过滤器和映射:
objects.filter { $0.isSelected } .map { $0.expertise }
You are returning the first selected expertise. To get the array of the selected expertise just use this
let selectedExpertises = Obj.filter{$0.isSelected == true}
Then you can get the expertises names like this
for expertise in selectedExpertises {
print(expertise.expertise)
}
Update: to get the array of expertises names :
var expertises: [String] = []
let selectedExpertises = Obj.filter{$0.isSelected == true}
for expertise in selectedExpertises {
expertises.append(expertise.expertise)
}
Another way:
var expertises: [String] = []
for expertise in Obj {
if expertise.isSelected {
expertises.append(expertise.expertise)
}
}
