Answer 1

In openFlowView.m file search this method

- (void)awakeFromNib {
    [self setUpInitialState];
}
Now when you find this replace this method by below or add lines of tapGestureRecognizer.

- (void)awakeFromNib {
    [self setUpInitialState];
    UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(screenTapped:)];   
    [tapRecognizer setNumberOfTapsRequired:2];
    [self addGestureRecognizer:tapRecognizer];
    [tapRecognizer release];    

}
screenTapped is my method that gets called when I tap twice on cover flow.

- (void)screenTapped:(UITapGestureRecognizer *)tap {
    NSLog(@"Screen tapped");
//put your points of your coverflow coordinates
    if(coverPointimage.x > 0 && coverPointimage.x <= 265 && coverPointimage.y >0 && coverPointimage.y <= 205){
        [self imageClicked];//either write code or made seperate method that should gets called when you do double tap.
    }


}

Hope this code will save your couple of hours.Happy Coding.
