ios - MPRemoteCommandCenter control center pause button doesn't update even after the audio file is paused -

-

i’m working on audio recording application deals mpremotecommandcenter class. i’ve setup command center play , pause commands. code snippet added below. i’m facing issue pausecommand.

from application start playing audio file updates control center file being played , play button changed pause button. when file being played, pause audio control center choosing pause button. invoking pausecommand handler in application , audio file paused control centre continuous update seek bar , pause button doesn’t change play button.

-(void) setupremotecontrols { mpremotecommandcenter *commandcenter = [mpremotecommandcenter sharedcommandcenter];  [commandcenter.pausecommand addtargetwithhandler:^mpremotecommandhandlerstatus(mpremotecommandevent *event) {      if ([self pauseaudioplayback])          return mpremotecommandhandlerstatussuccess;     else         return mpremotecommandhandlerstatuscommandfailed; } ];  [commandcenter.playcommand addtargetwithhandler:^mpremotecommandhandlerstatus(mpremotecommandevent *event) {      if ([self resumeaudioplayback])         return mpremotecommandhandlerstatussuccess;     else         return mpremotecommandhandlerstatuscommandfailed; } ];

}

// method invoked in both pauseaudioplayback & resumeaudioplayback methods

- (void) updateremotecontrols { mpremotecommandcenter *commandcenter = [mpremotecommandcenter sharedcommandcenter];  if (self.audioplayer) {     if (self.isplaying)         commandcenter.playcommand.enabled = no;     else if (self.isplaypaused)         commandcenter.playcommand.enabled = yes; } else     [self clearnowplayinginfo];

}

please let me know if additional information required.

for ios 9.2:

i've tried combinations of settings in mpnowplayinginfocenter , mpremotecommandcenter.

to stop updating seek bar enough set 

mpnowplayinginfocenter.defaultcenter().nowplayinginfo?[mpnowplayinginfopropertyplaybackrate] = 0.0 mpnowplayinginfocenter.defaultcenter().nowplayinginfo?[mpnowplayinginfopropertyelapsedplaybacktime] = player?.currenttime

but toggle pause button needed deactivate avaudiosession after pausing audioplayback.

avaudiosession.sharedinstance().setactive(false)

finally pausecommand handler looks like:

mpremotecommandcenter.sharedcommandcenter().pausecommand.addtargetwithhandler { (e) -> mpremotecommandhandlerstatus in         player?.pause()         let infocenter = mpnowplayinginfocenter.defaultcenter()         infocenter.nowplayinginfo?[mpnowplayinginfopropertyplaybackrate] = 0.0         infocenter.nowplayinginfo?[mpnowplayinginfopropertyelapsedplaybacktime] = player?.currenttime          _ = try? avaudiosession.sharedinstance().setactive(false)          return mpremotecommandhandlerstatus.success }

hope, helps somebody.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

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 .
