@implementation DropdownViewController
@synthesize tabview;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    menu = [NSArray arrayWithObjects:@"My Account", @"Terms of Use", @"Privacy Policy", @"Version",@"Logout", nil];
}


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


-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *simpleTableIdentifier = @"SimpleTableCell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];

    if (cell == nil)
    {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
    }

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

您可以尝试此代码

UIImageView *arrowImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"arrow"]];
arrowImageView.frame = CGRectMake(0, 0, 44, 44); // Or whatever you like
arrowImageView.center = //circle button.center. The button where you want it to be displayed.
[self.view addSubview:arrowImageView];

// Set the table below the image and add it to subview
tableView.frame = // Your frame
