Core Animation: Fehler Bytes zuzuteilen. unter Verwendung von Core-Plot auf dem iPad

Question

im neuen iPhone zu entwickeln, so wenden Sie sich bitte lehre mich auf Sachen, die ich verzichten kann. so dass im Grunde habe ich graphview.m die eine coreplotviewcontroller.view auf diese Weise erzeugt

    CorePlotViewController *aCorePlotViewController = [[CorePlotViewController alloc] initWithNibName:@"CorePlotViewController" bundle:nil];
aCorePlotViewController.view.bounds = CGRectMake(0,0,896,605);
aCorePlotViewController.view.center = CGPointMake(576, 374.5);
[aCorePlotViewController.view setTag:99];

[self.view addSubview:aCorePlotViewController.view];

ich habe eine Schaltfläche in graphview.m die Art von Refresh der Coreplotview auf diese Weise

[[self.view viewWithTag:99]removeFromSuperview];

CorePlotViewController *aCPView = [[CorePlotViewController alloc] initWithNibName:@"CorePlotViewController" bundle:nil];
aCPView.view.bounds = CGRectMake(0,0,896,605);
aCPView.view.center = CGPointMake(576, 374.5);
[aCPView.view setTag:99];
[self.view addSubview:aCPView.view];

im Simulator es gut funktioniert, die die coreplot Ansicht, die einen Graph hat wird aktualisiert. aber auf dem iPad, nachdem für eine Weile erfrischend, ich erhalte eine Fehlermeldung, die wie diese

angemeldet ist

Coreanimation. Fehlgeschlagen 2168448 Bytes zuweisen

Also im Denken vielleicht die Erinnerung, die er zugewiesen wurde nicht veröffentlicht? (Ich weiß nicht).

Answer 1

Sie sind nicht entweder Ihre CorePlotViewController Instanzen Freigabe, die im Laufe der Zeit zu einem Problem führen wird. Nach der Zugabe von der Auffassung der VC als Subview Sie den Controller freigeben kann, das heißt [aCorePlotViewController release];. Dann das gleiche gilt für die Auffrischungs.

Wenn das es nicht beheben, versuchen Sie eine Build-tun und analysiert, um zu sehen, wenn Sie anderswo Speicherprobleme haben.
