如何从NSTableViewCell
项目中检索当前标题部分的名称?
目前,我有一个名为configureCell
的方法,该方法确定如何设置自定义单元格的样式。此数据来自pList文件。
-(void)configureCell:(UITableViewCell *)tableViewCell forIndexPath:(NSIndexPath *)indexPath{
UILabel *label;
UIView *backView;
// NSString *country = [self tableView: tableViewCell titleForHeaderInSection:indexPath.section];
NSString *fatPercent = [[self.milkTypes valueForKey:@"Finland"] objectAtIndex:indexPath.row];
label = (UILabel *)[tableViewCell viewWithTag:1];
label.text = @"Fat Percent test";
backView = (UIView *)[tableViewCell viewWithTag:2];
backView.backgroundColor = [self colorWithHexString: fatPercent];
}
我在
*country
的行中注释掉的地方,我需要检索我所在的当前节。目前,它已静态设置为Finland
,这是pList中的数组名称。为了更好地理解我的代码的布局方式,以下是表控制器的大部分内容。
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return [self.milkTypes count];
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [[self.milkTypes allKeys] objectAtIndex:section];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSString *country = [self tableView:tableView titleForHeaderInSection:section];
return [[self.milkTypes valueForKey:country] count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdentifier;
UITableViewCell *cell;
cellIdentifier = [NSString stringWithFormat:@"MilkCell"];
cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==nil) {
cell = [self tableViewCellWithReuseIdentifier:cellIdentifier forIndexPath:indexPath];
}
[self configureCell:cell forIndexPath:indexPath];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
-(UITableViewCell *)tableViewCellWithReuseIdentifier:(NSString *)identifier forIndexPath:(NSIndexPath *)indexPath{
CGRect rect;
UILabel *label;
UIView *backView;
UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];
float center = (float) (40-20)/2;
rect = CGRectMake(15, center, 270, 20);
label = [[UILabel alloc] initWithFrame:rect];
label.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth;
label.tag = 1;
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor blackColor];
[cell.contentView addSubview:label];
[label release];
rect = CGRectMake(280, 10, 20, 40-20);
backView = [[UIView alloc] initWithFrame:rect];
backView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleWidth;
backView.backgroundColor = [UIColor clearColor];
backView.tag = 2;
[cell.contentView addSubview:backView];
[backView release];
return cell;
}
-(void)configureCell:(UITableViewCell *)tableViewCell forIndexPath:(NSIndexPath *)indexPath {
UILabel *label;
UIView *backView;
// NSString *country = [self tableView: tableViewCell titleForHeaderInSection:indexPath.section];
NSString *fatPercent = [[self.milkTypes valueForKey:@"Sweden"] objectAtIndex:indexPath.row];
label = (UILabel *)[tableViewCell viewWithTag:1];
label.text = @"Fat Percent test";
backView = (UIView *)[tableViewCell viewWithTag:2];
backView.backgroundColor = [self colorWithHexString: fatPercent];
}
最佳答案
看来您已经有了[[self.milkTypes allKeys] objectAtIndex:section]-只需使用它即可,因此
NSString *country = [[self.milkTypes allKeys] objectAtIndex: indexPath.section];
