나는 UICollectionView
을 가지고 있으며 과 image
을 collectionViewCell
에 설정하려고합니다. 불행히도 나는 그 문제에 대해 어떤 레이블이나 다른 것을 얻는 것 같지 않습니다.맞춤형 UICollectionViewCell을 만드는 방법
여기 내 코드입니다 :
- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath{
UICollectionViewCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:@"cellIdentifier" forIndexPath:indexPath];
UILabel *issue = [[UILabel alloc] initWithFrame:CGRectMake(0,10,cell.bounds.size.width,40)];
if(indexPath.item %2 == 0){
cell.backgroundColor=[UIColor blueColor];
issue.text = @"Some Text";
issue.textColor = [UIColor greenColor];
issue.textAlignment = NSTextAlignmentCenter;
}
else {
cell.backgroundColor=[UIColor redColor];
issue.text = @"Some Text";
issue.textColor = [UIColor greenColor];
issue.textAlignment = NSTextAlignmentCenter;
}
}
는 불행하게도 레이블이 표시되지되고 있으며 둘 다 레이블의 텍스트입니다.
업데이트 됨 :이 클래스 파일의 나머지 코드를 추가했습니다.

당신은 사용자 정의 클래스를 생성하고 UICollectionViewCell''대신 사용해야합니다. – vaibhav
그래서'UICollectionViewCell' 커스텀 클래스는 라벨의 세부 사항과 다른 객체를 포함하고 있습니까? –
사용자 정의 클래스를 작성하여 'cell.yourLabel.text = @ "일부 값"및 기타 미리 선언 된 다른 객체를 참조하여 UI 구성 요소를 유지 관리 할 수 있습니다. – vaibhav
