代碼：NGRightTableViewViewController.h

#import <UIKit/UIKit.h>
@protocol PulldownMenuDelegate
-(void)menuItemSelected:(NSIndexPath *)indexPath;
-(void)pullDownAnimated:(BOOL)open;
@end

@interface NGRightTableViewViewController : UITableViewController<UITableViewDataSource,UITableViewDelegate>{
id<PulldownMenuDelegate> pulldelegate;

}

@property (nonatomic, retain) id<PulldownMenuDelegate> pulldelegate;
@property (nonatomic,strong) NSMutableArray *tableViewArray;
@property (nonatomic,strong) NSString *cellString;

-(NSString *) cellString;
@end

NGViewController.h的代碼

#import <UIKit/UIKit.h>
#import "NGRightTableViewViewController.h"
@interface NGViewController : UIViewController<PulldownMenuDelegate>
//- (IBAction)jumpBut:(id)sender;

@property (nonatomic, retain) NGRightTableViewViewController *rtvv;
@end

.m部分代碼：

- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
// UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:viewController];

mArray=[[NSMutableArray alloc] initWithObjects:@"uuuuuu",@"qqqu",@"qqqq",@"rrrr",@"yyyyy", nil];

UIButton *secondBut=[[UIButton alloc] initWithFrame:CGRectMake(120, 340, 40, 40)];
[secondBut setTintColor:[UIColor blueColor]];
[secondBut setTitle:@"第二" forState:UIControlStateNormal];
[secondBut setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
secondBut.titleLabel.font = [UIFont fontWithName:@"System-Bold" size:25.0f];
[secondBut addTarget:self action:@selector(jumpBut:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:secondBut];


UIBarButtonItem *leftBarBtn = [[UIBarButtonItem alloc] initWithTitle:@"觸摸" style:UIBarButtonItemStyleBordered target:self action:@selector(leftBarBtnClicked:)];
self.navigationItem.leftBarButtonItem = leftBarBtn;

UIBarButtonItem *rightBarBtn = [[UIBarButtonItem alloc] initWithTitle:@"科目" style:UIBarButtonItemStyleBordered target:self action:@selector(rightBarBtnClicked:)];
self.navigationItem.rightBarButtonItem = rightBarBtn;
if (rtvv==nil) {
rtvv=[[NGRightTableViewViewController alloc] init];

}
rtvv.tableViewArray=mArray;
// rtvv.view.frame=CGRectMake(0, 0, 320, 300);
rtvv.view.frame=CGRectMake(150, 64, 165, 120);
[self addChildViewController:rtvv];
[self.view addSubview:rtvv.view];
rtvv.pulldelegate=self;
[rtvv.view setHidden:YES];
// [self.view presentedViewController:rtvv.view];

// [self.. reloadData];

}
