Im nouveau à objective c et essayant toujours de comprendre toute l'idée objective orientée. Dans mon application, j'ai un bouton coché (comme) qui est utilisé dans toutes les pages, donc au lieu d'avoir les méthodes de coche dans chaque vue, je veux les déplacer à leur propre classe et les appeler. Comment ferais-je cela?Comment puis-je déplacer ces méthodes dans sa propre classe?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object
{
...
//create check mark button
UIButton *checkButton = [[UIButton alloc] initWithFrame:CGRectMake(270, 0, 50, 90)];
//user has already check marked post
if ([checkActivityArray containsObject:[object objectId]]){
[checkButton setTitleColor: [UIColor blueColor] forState:UIControlStateNormal];
[checkButton addTarget:self action:@selector(minusCheckMark:) forControlEvents:UIControlEventTouchUpInside];
}
//user has NOT already check marked post
else{
[checkButton setTitleColor: [UIColor grayColor] forState:UIControlStateNormal];
[checkButton addTarget:self action:@selector(addCheckMark:) forControlEvents:UIControlEventTouchUpInside];
}
[checkButton setTitle:@"CH" forState:UIControlStateNormal];
[checkButton setTag:indexPath.row];
[cell.contentView addSubview:checkButton];
...
return cell;
