标题: ios - 以编程方式定位 UITableViewCell 的内容时使用什么代替 UITextAlignmentRight

在苹果自己的文档中，

https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TableView_iPhone/TableViewCells/TableViewCells.html

它建议在该页面的以下代码段中使用 UITextAlignmentRight:

Listing 5-7  Adding subviews to a cell’s content view
#define MAINLABEL_TAG 1
#define SECONDLABEL_TAG 2
#define PHOTO_TAG 3

- (UITableViewCell *)tableViewUITableView *)tableView cellForRowAtIndexPathNSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"ImageOnRightCell";

    UILabel *mainLabel, *secondLabel;
    UIImageView *photo;
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

        mainLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 220.0, 15.0)];
        mainLabel.tag = MAINLABEL_TAG;
        mainLabel.font = [UIFont systemFontOfSize:14.0];
        mainLabel.textAlignment = UITextAlignmentRight;
        mainLabel.textColor = [UIColor blackColor];
        mainLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:mainLabel];

        secondLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 20.0, 220.0, 25.0)];
        secondLabel.tag = SECONDLABEL_TAG;
        secondLabel.font = [UIFont systemFontOfSize:12.0];
        secondLabel.textAlignment = UITextAlignmentRight;
        secondLabel.textColor = [UIColor darkGrayColor];
        secondLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:secondLabel];

        photo = [[UIImageView alloc] initWithFrame:CGRectMake(225.0, 0.0, 80.0, 45.0)];
        photo.tag = PHOTO_TAG;
        photo.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:photo];
    } else {
        mainLabel = (UILabel *)[cell.contentView viewWithTag:MAINLABEL_TAG];
        secondLabel = (UILabel *)[cell.contentView viewWithTag:SECONDLABEL_TAG];
        photo = (UIImageView *)[cell.contentView viewWithTagHOTO_TAG];
    }
    NSDictionary *aDict = [self.list objectAtIndex:indexPath.row];
    mainLabel.text = [aDict objectForKey"mainTitleKey"];
    secondLabel.text = [aDict objectForKey"secondaryTitleKey"];
    NSString *imagePath = [[NSBundle mainBundle] pathForResource:[aDict objectForKey"imageKey"] ofType"png"];
    UIImage *theImage = [UIImage imageWithContentsOfFile:imagePath];
    photo.image = theImage;

    return cell;
}

但是，Xcode 7 表示 UITextAlignmentRight 自 iOS 6.0 以来已被弃用。然而，Xcode 并没有说明用什么来代替它。请推荐使用什么来代替 UITextAlignmentRight

Best Answer-推荐答案

你可以使用:NSTextAlignment

label.textAlignment = NSTextAlignmentRight
