如何使用/导入SWTableViewCell库

Question

我想使用第三方图书馆＆＃34; Here＆＃34;。

我的代码没有产生任何错误，它可以显示单元格，但滑动不起作用。我怀疑是，我在导入图书馆时遗漏了一些东西。

我已经阅读了如何在＆＃34; Here＆＃34;中实现此库。和＆＃34; Here＆＃34;。但他们都没有告诉我如何导入图书馆。

＆＃34; Here＆＃34;是我的项目结构，显示我如何导入库：

在viewController.h：

#import <UIKit/UIKit.h>
#import "SWTableViewCell.h"

@interface ViewController : UITableViewController <UITableViewDelegate,         UITableViewDataSource, SWTableViewCellDelegate>

@end

在viewController.m：

#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [self.letterData count];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath     *)indexPath {
 NSLog(@"cell selected at index path %ld:%ld", (long)indexPath.section,   (long)indexPath.row);
NSLog(@"selected cell index path is %@", [self.tableView indexPathForSelectedRow]);

if (!tableView.isEditing) {
    [tableView deselectRowAtIndexPath:indexPath animated:YES];
}
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//    static NSString *cellIdentifier = @"Cell";
//    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

static NSString *cellIdentifier = @"Cell";

SWTableViewCell *cell = (SWTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil) {

    cell = [[SWTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle     reuseIdentifier:cellIdentifier];
    cell.leftUtilityButtons = [self leftButtons];
    cell.rightUtilityButtons = [self rightButtons];
    cell.delegate = self;
}

cell.textLabel.text = self.letterData[indexPath.row];

return cell;

return cell;
}
