scroll view can scroll but display nothing
<p>I am having a main scroll view containing UIImage and UIButtons on top... I would like to have another sub scroll view holding some buttons on it. I added them by StoryBoard. What I do is </p>

<pre><code>// ButtonInfo is a NSDictionary with some key/value on it
CGFloat x           = [[buttonInfo objectForKey:@"left"] floatValue];
CGFloat y           = [[buttonInfo objectForKey:@"top"] floatValue];
CGFloat width       = [[buttonInfo objectForKey:@"width"] floatValue];
CGFloat height      = [[buttonInfo objectForKey:@"height"] floatValue]; 
CGRect frame        = CGRectMake(x, y, width, height);

// Create a newButton with given above frame
DetailCellButton *newButton = [[DetailCellButton alloc] initWithFrame:frame];
newButton.buttonName = [buttonInfo objectForKey:@"name"];

// Create an UIImageView with same frame
UIImageView *myIconView = [[UIImageView alloc] initWithFrame:frame];


[myIconView bringSubviewToFront:newButton];
[myIconView setUserInteractionEnabled:YES];

// Add a button to mySimilarScrollView
[mySimilarScrollView addSubview: newButton]; 

// Add UIImageView to mySimilarScrollView 
[mySimilarScrollView addSubview:myIconView];

// Bring button to front of mySimilarScrollVew       
[mySimilarScrollView bringSubviewToFront:newButton];
</code></pre>

<p>When I run the program, I can see my scrollView and it is scrollable. However, the problem is it is containing nothing...For the main scrollView, i do the same thing with button and UIImageView and it works but mySimilarScrollView does not 
If I am just making a mistake.. Please correct me...</p>
