Model 클래스를 사용하여 tableView 및 collectionView의 모든 셀을 관리하는 데 사용하는 매우 쉬운 방법을 찾았으며 이것은 완벽하게 작동합니다.
실제로 이것을 처리하는 훨씬 더 좋은 방법이 있습니다. 이것은 셀과 값을 관리하는 데 효과적입니다.
다음은 내 출력 (스크린 샷)이므로 다음을 참조하십시오.
- 모델 클래스 를 생성하는 것은 매우 간단 합니다. 아래 절차를 따르십시오. name으로 신속한 클래스를
RNCheckedModel만들고 아래와 같이 코드를 작성합니다.
class RNCheckedModel: NSObject {
var is_check = false
var user_name = ""
}
- 셀 클래스 만들기
class InviteCell: UITableViewCell {
@IBOutlet var imgProfileImage: UIImageView!
@IBOutlet var btnCheck: UIButton!
@IBOutlet var lblName: UILabel!
@IBOutlet var lblEmail: UILabel!
}
- 마지막으로 UITableView 를 사용할 때 UIViewController 에서 모델 클래스 를 사용하십시오 .
class RNInviteVC: UIViewController, UITableViewDelegate, UITableViewDataSource {
@IBOutlet var inviteTableView: UITableView!
@IBOutlet var btnInvite: UIButton!
var checkArray : NSMutableArray = NSMutableArray()
var userName : NSMutableArray = NSMutableArray()
override func viewDidLoad() {
super.viewDidLoad()
btnInvite.layer.borderWidth = 1.5
btnInvite.layer.cornerRadius = btnInvite.frame.height / 2
btnInvite.layer.borderColor = hexColor(hex: "#512DA8").cgColor
var userName1 =["Olivia","Amelia","Emily","Isla","Ava","Lily","Sophia","Ella","Jessica","Mia","Grace","Evie","Sophie","Poppy","Isabella","Charlotte","Freya","Ruby","Daisy","Alice"]
self.userName.removeAllObjects()
for items in userName1 {
print(items)
let model = RNCheckedModel()
model.user_name = items
model.is_check = false
self.userName.add(model)
}
}
