To use this category simply import the UIView+DHNHideByConstraints.h and call ether hideVertical: or hideHorizontal: on the view you would like to hide.
#import "UIView+DHNHideByConstraints.h"
...
- (void)hideViews {
[self.myViewToHide1 hideVertical:YES];
[self.myViewToHide2 hideHorizontal:YES];
}
- (void)showViews {
[self.myViewToHide1 hideVertical:NO];
[self.myViewToHide2 hideHorizontal:NO];

When using this category make sure you do not alter the content of the views (and its subviews) when hidden. This can cause unexpected effects on the views layout, especial on UILabel, UIButton ect. If you must change the content of the hidden view, unhide it first, change its content and hide again.
