Question

+ i

 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]; 

şu anda kaldırıp tekrar ekleyerek grafiği ferahlatıcı im bu yolla bir coreplotviewcontroller.view yaratan var graphview.m var.

[[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]; 

Ama bu belleğin bir sürü yukarı alacağını ve sonunda ben CoreAnimation için artık bellek tahsis etmek mümkün olmaz (im bu hata günlüğe alma).

Grafiği yeniden nasıl yeniden oluştururum? Grafiği yeniden çizmek için coreplotviewcontroller.m'de bir yöntem oluşturmayı tahmin ediyorum.

CorePlotViewController.h şöyle CorePlotViewController.h ve .m için benim şimdiki kodlardır

#import <UIKit/UIKit.h> 
#import "CorePlot-CocoaTouch.h" 
#import "GraphView.h" 

@interface CorePlotViewController : UIViewController <CPPlotDataSource> 

{ 
CPXYGraph *graph; 

NSMutableArray *dataForPlot; 
NSMutableArray *dataForPlot2; 

NSMutableArray *finalDatas; 

NSMutableArray *numofdata; 
NSMutableArray *numofdata2; 
} 

@property(readwrite, retain, nonatomic) NSMutableArray *dataForPlot; 
@property(readwrite, retain, nonatomic) NSMutableArray *dataForPlot2; 
@property(readwrite, retain, nonatomic) NSMutableArray *finalDatas; 

@property(readwrite, retain, nonatomic) NSMutableArray *numofdata; 
@property(readwrite, retain, nonatomic) NSMutableArray *numofdata2; 

@end

Kullanım [graph reloadData]; . Hepsini aynı anda güncellemeniz gerekmiyorsa, -reloadData mesajını tekil parsellere gönderebilirsiniz.
