How to center any subview horizontally in parent UIView but not vertically?

Question

How to center any subview in its parent UIview only horizontally, not vertically. I tried child.center = parent.center but it place my child view in the center of the parent view both horizontally and vertically. How can i align it in center just horizontally. Thanks

Answer 1

Changing only the center like this may help

child.center = CGPointMake(CGRectGetMidX(parentView.bounds), child.center.y);

Answer 2

You can't modify the x property of the UIViewController's center directly, but you can do the following:

CGPoint center = child.center;
center.x = parent.center.x;
child.center = center;

Answer 3

Try this,

subview.frame = CGRectMake(((parentView.frame.size.width/2)-(subview.frame.size.width/2)),subview.frame.origin.y,subview.frame.size.width,subview.frame.size.height);
