iphone - iOS 8.4 MPNowPlayingInfoCenter skip/prev disappeared -

-

i'm working on music playing app , in previous ios versions media player show play/pause skip , prev buttons. now, 8.4 update, shown play/pause. i'm updating mpnowplayinginfocenter in usual way:

nsdictionary* nowplayinginfo = @{     mpmediaitempropertytitle:[self.currentsong title],     mpmediaitempropertyartist:[self.currentsong artist],     mpmediaitempropertyplaybackduration:[nsnumber numberwithdouble:(double) self.duration],     mpnowplayinginfopropertyelapsedplaybacktime: [nsnumber numberwithdouble:(double)self.currentplaybacktime],     mpnowplayinginfopropertyplaybackrate: self.isplaying ? @1.0 : @0.0,     mpmediaitempropertyartwork: mediaplayerartwork,     mpnowplayinginfopropertyplaybackqueueindex: [nsnumber numberwithinteger:playqueue.queueposition],     mpnowplayinginfopropertyplaybackqueuecount: [nsnumber numberwithinteger:playqueue.queueids.count] }; [[mpnowplayinginfocenter defaultcenter] setnowplayinginfo:nowplayinginfo];

but result is... enter image description here

and enter image description here

thanks help!

in order next , prev buttons need add:

[[mpremotecommandcenter sharedcommandcenter].nexttrackcommand addtarget:self action:@selector(remotenextprevtrackcommandreceived:)]; [[mpremotecommandcenter sharedcommandcenter].previoustrackcommand addtarget:self action:@selector(remotenextprevtrackcommandreceived:)];

i added in appdelegate's

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {

if you're receiving remote events action method can empty:

-(void) remotenextprevtrackcommandreceived:(id)event {}

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
