Failed to set scrollview's position - ios

Question

I am new in iOS. I am building a basic project where I have two view controllers.
First one named as tabViewController and the second one as detailViewController.
in tabViewController I have a collectionView. When I am tapping on collection view cell it is pushing to detail view controller. In detail view controller there are three image views. One is just in front of the screen (x=0, y=0, width=320, height=420). The other two imageViews are in the positions at left and right side of the one which is in front of the screen. The two imageViews are in positions as x=-330,y=0,width=320,height=420 and x=330,y=0,width=320,height=420. Consider just about iPhone5.
Now, the problem that is happening is I cant make the scrollView's position to see the image that is in left side of the screen.
The code I have written is
- (void)viewDidLoad {
[super viewDidLoad];
_myScrollView.delegate = self;
_myScrollView.pagingEnabled = YES;
_selectedImageString = [_patternArray objectAtIndex:*(_selectedIndex)];
_strImageNext = [_patternArray objectAtIndex:*(_selectedIndex)+1];
_myScrollView.bounds = CGRectMake(_myImageView2.frame.origin.x, _myScrollView.frame.origin.y, _myScrollView.frame.size.width, _myScrollView.frame.size.height);
if (*(_selectedIndex) == 0) {
_strImagePrevious = nil;
}
else{
_strImagePrevious = [_patternArray objectAtIndex:*(_selectedIndex)-1];
}
self.navigationController.navigationBar.hidden = NO;
_myImageView.image = [UIImage imageNamed:_selectedImageString];
_myImageView.frame = CGRectMake(_myScrollView.frame.origin.x, _myScrollView.frame.origin.y, _myScrollView.frame.size.width, _myScrollView.frame.size.height);
self.myScrollView.backgroundColor = [UIColor yellowColor];
_myImageView3.image = [UIImage imageNamed:_strImageNext];
if (*(_selectedIndex) == 0) {
_myImageView2.image = nil;
}
else {
_myImageView2.image = [UIImage imageNamed:_strImagePrevious];
}
[_myScrollView setScrollEnabled:YES];
[_myScrollView setContentSize:CGSizeMake((_myImageView2.frame.size.width+_myImageView2.frame.size.width+_myImageView2.frame.size.width+_myImageView.frame.size.width+ 30.0), _myScrollView.frame.size.height)];
}

Here is a sample code to move left with contentOffset. Hope it will help you.
your_scroll.contentOffset = CGPointMake(-100.0, 0.0);
