我們以前通常會這樣做
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentiferId = @"MomentsViewControllerCellID";
MomentsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentiferId];
if (cell == nil) {
NSArray *nibs = [[NSBundle mainBundle]loadNibNamed:@"MomentsCell" owner:nil options:nil];
cell = [nibs lastObject];
cell.backgroundColor = [UIColor clearColor];
};
}
return cell;
}
現在我們可以這么用
采用registerNib的方式,并且把設置都放在了willDisplayCell方法中了,而不是以前我們經常用的cellForRowAtIndexPath
這個方法我試了下,如果我們在xib中設置了 Identifier,那么此處的必須一致,否則會crash的
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyCustomCell * cell = [tableView dequeueReusableCellWithIdentifier:@"myCell"];
if (!cell)
{
[tableView registerNib:[UINib nibWithNibName:@"MyCustomCell" bundle:nil] forCellReuseIdentifier:@"myCell"];
cell = [tableView dequeueReusableCellWithIdentifier:@"myCell"];
}
return cell;
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(MyCustomCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.leftLabel.text = [self.items objectAtIndex:indexPath.row];
cell.rightLabel.text = [self.items objectAtIndex:indexPath.row];
cell.middleLabel.text = [self.items objectAtIndex:indexPath.row];
}
