Question

I’m trying to create gaps between the UIImageViews, which are subviews added into a UIScrollView.

And I thought I could do the following by modifying the CGRect of the UIImageView.
CGRect frame = imageView.frame;

frame.origin.x = <some values>
frame.origin.y = 0
imageView.frame = frame;

By modifying the x values, I assumed it will help me with the position of the UIImageViews inside the UIScrollView.

However, I realized whichever values I set for the frame.origin.x does not really matter. As each UIImageView inside the UIScrollView will be positioned side by side without any empty space.

I think you’re doing it in the wrong way. You can’t edit view’s position by

view.frame.origin.x = something;

You should assign a new frame, like this:

view.frame = CGRectMake(x, y, w, h);

In your case it will look like this:

CGRect frame = imageView.frame;
CGFloat frameX = frame.origin.x;
CGFloat frameY = frame.origin.y;
CGFloat frameW = frame.size.width;
CGFloat frameH = frame.size.height;

frameX = <some values>
frameY = 0;

imageView.frame = CGRectMake(frameX, frameY, frameW, frameH);
