ios - Swift 3: Can not convert value of type 'int' to expected argument type 'DispatchQueue.GlobalQueuePriority' -


swift 3.0: receiving error can not convert value of type 'int' expected argument type 'dispatchqueue.globalqueuepriority' on creating dispatch async queue 

dispatchqueue.global(priority: 0).async(execute: { () -> void in  })

warning, deprecated in ios 8, see below latest

dispatchqueue.global expects dispatchqueue.globalqueuepriority enum, is:

  • high
  • default
  • low
  • background

so in case, write:

dispatchqueue.global(priority: .background).async(execute: { () -> void in  })

if want lowest priority.

a quick check reveals, dispatchqueue.global(priority:_) deprecated in ios 8.

latest solution:

dispatchqueue.global(qos: .background).async {  }

which gives more options choose from:

  • background
  • utility
  • default
  • userinitiated
  • userinteractive
  • unspecified

angular - Is it possible to get native element for formControl? -

i've got angular2 reactive form . created formcontrol s , assigned input fields by [formcontrol]=... . understand creates nativeelement <-> formcontrol link. my question: possible nativeelement formcontrol ? wanna myformcontrol.nativeelement.focus() i can share 1 terrible solution works me. in reactive forms can use either 1) formcontroldirective ts mycontrol = new formcontrol('') template <input type="text" [formcontrol]="mycontrol"> or 2) formcontrolname ts myform: formgroup; constructor(private fb: formbuilder) {} ngoninit() { this.myform = this.fb.group({ foo: '' }); } template <form [formgroup]="myform"> <input type="text" formcontrolname="foo"> </form> so these directives write patch like 1) formcontroldirective const originformcontrolngonchanges = formcontroldirective.prototype.ngonchanges; formcontroldirective.proto

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
