ios - Swift3 center UIbutton -


ok, have added button .swift storyboard, have added following code viewcontroller.swift

 @iboutlet weak var hellobutton: uibutton!  override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.      hellobutton.frame.origin.x = view.frame.size.width / 2    }

however when test on iphone 5s moves right of screen , not make centered. unsure need make button centered.

yes first helloworld app, , maybe on head, understand web programing, , understand make center automaticilly need have screen view width total , button width. need button divide screen view width 2.

for example in css this

#button{margin:0 auto;}

but not html or css. it's swift3

try this:

    hellobutton.center.x = view.frame.width/2

yours not correct because origin.x first point (top left) of button view, not center of view, can change it's background color different color see it

also, variable name should lowercase, followed code convention

unity3d - Rotate an object to face an opposite direction -

i have object , b. when click on object b, rotates object b (a faces b). b doesn't face a. need following : when faces b, need face opposite direction. have code rotating @ b. how rotate face opposite direction after that? vector3 targetdirection = target - transform.position; float step = speed * time.deltatime; vector3 newdirection = vector3.rotatetowards (turretdome.transform.forward, targetdirection, step, 0.0f); turretdome.transform.rotation = quaternion.lookrotation (newdirection); you object facing object b, want inverse direction of object after that? objecta.transform.rotation = quaternion.inverse(objecta.transform.rotation) but lets assume example turretdome object a, (negate direction): turretdome.transform.rotation = quaternion.lookrotation (-newdirection); naturally, both of these snippets not show how smoothen rotation, seem know how use time.deltatime. just incase unsure, quaternion.lerp this
