UITableViewCell 左滑删除

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
    return YES;
}

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

     if (editingStyle == UITableViewCellEditingStyleDelete) {
         [dataArray removeObjectAtIndex:indexPath.row];
         // Delete the row from the data source.
         [testTableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

     }
     else if (editingStyle == UITableViewCellEditingStyleInsert) {
     // Create a new instance of the appropriate class, insert it into the array, and add a new row to the table view.
     }
 }

 按理说故事讲到这里也就讲完了.但是笔者想延伸一下.注意看图二划动以后的"Delete",你有没有想把这个东东改掉的冲动呢?比如改成:下载?其实很简单,其实下面这个代理方法:

 

- (NSString *)tableView:(UITableView *)tableView titleForDeleteConfirmationButtonForRowAtIndexPath:(NSIndexPath *)indexPath{
        return @"下载";
}
