osx - Frame-by-frame animation in MacOs -


i'm looking way frame-by-frame programmatically drawn animations in macos application (not keyframe property animation). have tried drawing calayers using drawlayer:incontext: delegate method, calling setneedsdisplay draw each frame, i'm getting poor performance doing way. there recommended way type of animation in cocoa?

a way entirely custom animations using cadisplaylink (ios) or cvdisplaylink (macos). cvdisplaylink timer fires display refreshes.

you can calculate own timing functions based on values off cvdisplaylink. api still c bit cumbersome use, in swift, once how functions works charm.

i have had experiences cvdisplaylink, layers. performant. able animate 1000+ layers cvdisplaylink driven @ 60fps without problems.

if need in using api, feel free ask!

alternative:

if want use more modern api, can recommend spritekit. there nice animation apis well. , perform good. apple uses draw more complex views (like memory debugger in xcode).

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

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
