我创建了一个从 .xml 文件解析的 RSS 阅读器。numberOfRowsInSection和cellForRowAtIndexPath如下所示:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return self.parseResults.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
//Check if cell is nil. If it is create a new instance of it
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// Configure titleLabel
cell.textLabel.text = [[self.parseResults objectAtIndex:indexPath.row] objectForKey:@"title"];
cell.textLabel.numberOfLines = 2;
//Configure detailTitleLabel
cell.detailTextLabel.text = [[self.parseResults objectAtIndex:indexPath.row] objectForKey:@"summary"];
cell.detailTextLabel.numberOfLines = 2;
//Set accessoryType
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
//Set font and style
cell.selectionStyle = UITableViewCellSelectionStyleGray;
cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
return cell;
}
我正在尝试创建搜索栏和搜索显示控制器,但不确定如何在 UITableView 中搜索objectForKey “标题”或objectForKey “摘要”。
任何帮助将不胜感激。
