iOS Swift Add SVG Image to button like Android -


in android, can import svg vector xml, use drawable, change colors of svg icons , add button

void setsvgicnforbtnfnc(button setbtnvar, int setsvgvar, int setclrvar, string posvar) {     drawable devdmjvar = getdrawable(setsvgvar);     devdmjvar.setbounds(0,0,dpx24,dpx24);     devdmjvar.setcolorfilter(new porterduffcolorfilter(setclrvar, porterduff.mode.src_in));     switch (posvar)     {         case "tit" : setbtnvar.setcompounddrawables(null, devdmjvar, null, null); break;         case "rit" : setbtnvar.setcompounddrawables(null, null, devdmjvar, null); break;         case "pit" : setbtnvar.setcompounddrawables(null, null, null, devdmjvar); break;         default: setbtnvar.setcompounddrawables(devdmjvar, null, null, null); break;     } }

how do in swift iphones ?

setbtnvar.setimage(<image: uiimage?>, forstate: <uicontrolstate>)

upd: see useyourloaf blog post

just found on erica sadun blog post on ios 11 could use vector assets.

what "vector assets" mean:

if click box, vector data shipped application. which, on 1 hand, makes application little bit larger, because vector data takes space. on other hand, give opportunity scale these images, might useful in number of different situations. so, 1 is, if know particular image going used @ multiple sizes. might less obvious. so, 1 case symbolic glyph should resize dynamic type. since we're thinking dynamic type, should thinking having glyphs appearing next type resize appropriately. case that's not obvious, tab bar images. ... there's great accessibility feature recommend supporting, allows user have turned dynamic type size up. ... so, recommend doing increase usability of app across users

how use:

  1. convert svg file pdf, e.g. on zamzar.com
  2. add pdf assets.xcassets
    • click "preserve vector data" imported pdf.
  3. create uiimageview in uiviewcontroller , assign pdf file uiimage.

ios < 11

there no native way use svg image.

take @ macaw

import framework via cocoapod

pod "macaw", "0.8.2"

check example project: how render tiger.svg (located in project directory, not in assets.xcassets file)

import uikit import macaw  class svgexampleview: macawview {      required init?(coder adecoder: nscoder) {         super.init(node: svgparser.parse(path: "tiger"), coder: adecoder)     }  }

there other third-party libraries of course:

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
