代码：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的代码：

#import <UIKit/UIKit.h>

#import "NGRightTableViewViewController.h"

@interface NGViewController : UIViewController<PulldownMenuDelegate>

//- (IBAction)jumpBut:(id)sender;

@property (nonatomic, retain) NGRightTableViewViewController *rtvv;

@end

.m部分代码：

- (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:@"触摸" 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];

}
