- (void)viewDidLoad {
    [super viewDidLoad];

    [self CreatUI];

}

-(void)CreatUI{

    arrayImage = [NSMutableArray new];
    for  (int i = 0; i<9; i++) {

        UIImageView * imaVi = [[UIImageView alloc] initWithFrame:CGRectMake(i%3*90+20,i/3*100+50, 80, 80)];
        imaVi.tag = i;
        imaVi.userInteractionEnabled = YES;
        UITapGestureRecognizer * tap = [[UITapGestureRecognizer alloc]init];

        [tap addTarget:self action:@selector(tapaction:)];

        [imaVi addGestureRecognizer:tap];
        imaVi.image = [UIImage imageNamed:[NSString stringWithFormat:@"%d.jpg",i+1]];
        [self.view addSubview:imaVi];

        [arrayImage addObject:[NSString stringWithFormat:@"%d.jpg",i+1]];

    }

}

-(void)tapaction:(UITapGestureRecognizer*)tap{

    UIView * vi = tap.view;
    SDPhotoBrowser * broser = [[SDPhotoBrowser alloc] init];
    broser.currentImageIndex = vi.tag;
    broser.sourceImagesContainerView = self.view;
    broser.imageCount =arrayImage.count;
    broser.delegate = self;
    [broser show];
