objective c - String substitution with variable constants -


this question has answer here:

in project, define urls such:

#define termsurl       @"http://127.0.0.1:8000/terms/" #define privacyurl     @"http://127.0.0.1:8000/privacy/" ...

since root url (http://127.0.0.1:8000/) same, there way set constant, , use string substitution remaining pieces?

for example, in other files, this:

nsstring *devbaseurl = @"http://127.0.0.1:8000/"; nsstring *url1 = [nsstring stringwithformat:@"%@terms/", devbaseurl];

is there way current approach?

shared.h 

#define termsurl       @"http://127.0.0.1:8000/terms/" #define privacyurl     @"http://127.0.0.1:8000/privacy/" #define url_base       @"http://127.0.0.1:8000/"

yourclass.m 

nsstring * stringurlbase = url_base; nsstring *url1 = [nsstring stringwithformat:@"%@terms/", stringurlbase];

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
