我有一个工作正常的表格视图。唯一的事情是，当一个单元格被选中时，它会保持突出显示。因此，如果我点击一个单元格以转到另一个视图并点击导航栏上的后退按钮以返回表格视图，我选择的单元格仍然突出显示。我怎样才能解决这个问题？

#import "SocialNetworks.h"
#import "Facebook.h"
#import "Twitter.h"
#import "YouTube.h"
#import "CustomCellBackground.h"

@interface SocialNetworks ()

@end

@implementation SocialNetworks
{
    NSMutableArray *mbTableData;
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    mbTableData = [NSMutableArray arrayWithObjects:@"Facebook", @"Twitter", @"YouTube", nil];
    self.title = @"Social Networks";
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return [mbTableData count];
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *mbTableIdentifier = @"SimpleTableItem";
    UIImageView *image = [[UIImageView alloc]init];
    image.image = [UIImage imageNamed:@"CellImage.png"];

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:mbTableIdentifier];

    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:mbTableIdentifier];
        cell.textLabel.font=[UIFont systemFontOfSize:16.0];
    }

    // cell.backgroundView = [[CustomCellBackground alloc] init];
    // cell.selectedBackgroundView = [[CustomCellBackground alloc] init];
    cell.textLabel.font = [UIFont fontWithName:@"FranklinGothicStd-ExtraCond" size:24.0];
    cell.textLabel.backgroundColor = [UIColor clearColor];
    cell.textLabel.highlightedTextColor = [UIColor darkGrayColor];
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.backgroundView = image;

    NSLog(@"cell separator style: %d separator color: %@", tableView.separatorStyle, tableView.separatorColor);

    cell.textLabel.text = [mbTableData objectAtIndex:indexPath.row];
    return cell;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{

    if (indexPath.row == 0)
    {
        Facebook *facebook = [[Facebook alloc] initWithNibName:@"Facebook" bundle:[NSBundle  mainBundle]];
        [self.navigationController pushViewController:facebook animated:YES];
    }
    else if (indexPath.row == 1)
    {
        Twitter *twitter = [[Twitter alloc] initWithNibName:@"Twitter" bundle:[NSBundle  mainBundle]];
        [self.navigationController pushViewController:twitter animated:YES];
    }
    else if (indexPath.row == 2)
    {
        YouTube *youTube = [[YouTube alloc] initWithNibName:@"YouTube" bundle:[NSBundle  mainBundle]];
        [self.navigationController pushViewController:youTube animated:YES];
    }


}


@end

编辑：我在发布问题后就想通了。

[tableView deselectRowAtIndexPath:indexPath animated:YES];

在didSelectRowAtIndexPath您只需要拨打电话即可取消选择该行

    [self.tableView deselectRowAtIndexPath:indexPath animated:YES];

您可以随时使用：

[tableView deselectRowAtIndexPath:indexPath animated:YES];

在 tableView:didSelectRowAtIndexPath: 方法中。
