+ मैं एक graphview.m है जो इस तरह सेकोर-भूखंड - ताज़ा ग्राफ गतिशील आईपैड
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];
[aCorePlotViewController.view release];
अभी निकालकर और पुन: जोड़कर ग्राफ ताज़ा im में एक coreplotviewcontroller.view बनाता है।
[[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];
[aCPView release];
लेकिन इस स्मृति के बहुत ऊपर ले जाएगा और अंत में मैं CoreAnimation को अब और स्मृति को आबंटित करने में सक्षम नहीं होगा (आईएम इस त्रुटि लॉग इन हो रही)।
तो मैं फिर से ग्राफ को फिर से कैसे बना सकता हूं? संभवतः ग्राफ़ को फिर से निकालने के लिए coreplotviewcontroller.m में एक विधि बनाने का उपयोग कर। CorePlotViewController.h और मीटर के लिए मेरे वर्तमान कोड के रूप में
