我正嘗試將圖像插入基於我們公司目錄中的人員搜索的表格單元格中。這很容易做到,但問題是有些人沒有照片,所以他們就會拋棄他們的關係。如果沒有圖片,有沒有辦法讓單元格保持空白,並且不會將文本滑過?這是我的細胞結構看起來像:iPad自定義表格單元格幫助
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
Person *aPerson = [appDelegate.people objectAtIndex:indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:@"%@ %@", aPerson.first_name, aPerson.last_name];
cell.detailTextLabel.text = [NSString stringWithFormat:@"%@, %@, %@", aPerson.sso, aPerson.email, aPerson.business_name];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
//trin the newlines out of file url
NSString *trimmedPath = [aPerson.image_path stringByTrimmingCharactersInSet:[NSCharacterSet newlineCharacterSet]];
if ([trimmedPath length] != 0) {
//concat url and retrieve data
NSURL *url = [[NSURL alloc] initWithString:[NSString stringWithFormat:@"http://******.*****.com/%@", trimmedPath]];
NSData *imgData = [NSData dataWithContentsOfURL:url];
//Save into cell
UIImage *theImage = [UIImage imageWithData:imgData];
cell.imageView.image = theImage;
return cell;
} else {
return cell;
}
任何想法?謝謝!
啊,你知道什麼,這是如此簡單,但可能會工作。謝謝! – gabaum10 2010-08-12 19:13:25
