@property (nonatomic, retain) nstimer *mytimer; @synthesize mytimer; - (void)viewdidload { [self mytimermethod]; [super viewdidload]; } - (void)mytimermethod{ nslog(@"mytimermethod called"); mytimer = [nstimer scheduledtimerwithtimeinterval:2.4 target:self selector:@selector(updateview:) userinfo:nil repeats:yes]; } - (void)updateview:(nstimer *)thetimer { if (index < [textarray count]) { self.textview.text = [self.textarray objectatindex:index]; self.imageview.image = [self.imagesarray objectatindex:index]; index++; }else{ index = 0; }

i m trying pause , resume mytimer mainviewcontroller

in mainviewcontroller.h

@class oneviewcontroller; @property (strong, nonatomic) oneviewcontroller *oneviewcontroller; @synthesize oneviewcontroller = _oneviewcontroller; -(void)playpauseaction:(id)sender { if([audioplayer isplaying]) { [sender setimage:[uiimage imagenamed:@"music.png"] forstate:uicontrolstatenormal]; [audioplayer pause]; [[oneviewcontroller mytimer] invalidate]; **\\no known class method selector 'mytimer'** }else{ [sender setimage:[uiimage imagenamed:@"audiostop.png"] forstate:uicontrolstatenormal]; [audioplayer play]; [[oneviewcontroller mytimer] fire]; **\\no known class method selector 'mytimer'** if(isfirsttime == yes) { self.timer = [nstimer scheduledtimerwithtimeinterval:06.0 target:self selector:@selector(displayviewsaction:) userinfo:nil repeats:no]; isfirsttime = no; } } }

how can prepare error.

thanks help.

instead of [[oneviewcontroller mytimer] invalidate]; utilize [self.oneviewcontroller.mytimer invalidate];

also, in oneviewcontroller implementation, instead of mytimer = [nstimer scheduledtimerwithtimeinterval:..... utilize self.mytimer = [nstimer scheduledtimerwithtimeinterval:.....
