UIView flip vertically
13,794
I realize this is an old question, but I'll leave this here anyway. The following would flip the view vertically using just the y-scale of the layer, so it would be my preference:
self.view.layer.transform = CGAffineTransform(scaleX: 1, y: -1)

I know it's probably a dummy question, but I have to ask: How to flip a
UIView
vertically? I'm not asking for doing a animation, but just flip it.I can do vertical flip a
UILabel
by:label1.layer.transform = CATransform3DMakeRotation(M_PI, 1.0f, 0.0f, 0.0f);
and turn it back by:
label1.layer.transform = CATransform3DMakeRotation(M_PI, 0.0f, 0.0f, 0.0f);
But when I'm doing it to a view:
self.view.layer.transform = CATransform3DMakeRotation(M_PI, 1.0f, 0.0f, 0.0f);
I think it only rotate half way... So, any ideas?
Thanks guys.

QuangLoc over 3 yearsI see you miss the code, if self is kind of UIView, you can use
self.transform = CGAffineTransform(scaleX: 1, y: -1)
if you want to use layer.transform, it is kind of CATransform3D, so the code isself.layer.transform = CATransform3DMakeScale(1, -1, 1)
