グラフにEASYGRAPHAPIを使用しているiPhoneアプリがあります。パーセンテージとグラフチャートを描画する表示ビューを作成しています。アプリの作成時にこの値が動的に表示されるようにします。パーセンテージが78％の場合と同様に、これをどのように割り当てる必要がありますか。表示ビューに対する私のコードの別のビューである値

表示ビュー

 #import <UIKit/UIKit.h>
 @interface Display : UIView {

 }

 @end



  #import "Display.h"
  #import "ECGraph.h"
 @implementation Display


 - (id)initWithFrame:(CGRect)frame {

 self = [super initWithFrame:frame];
 if (self) {
    // Initialization code.
 }
 return self;
  }


- (void)drawRect:(CGRect)rect {
// Drawing code


CGContextRef _context = UIGraphicsGetCurrentContext();

ECGraph *graph = [[ECGraph alloc] initWithFrame:CGRectMake(500,-320,320, 200) withContext:_context isPortrait:NO];


ECGraphItem *item1 = [[ECGraphItem alloc] init];
item1.isPercentage = YES;
item1.yValue = 80;

パーセンテージを次のようにtotoalpercentageに設定したいのですが、GraohsViewCOntrollerにあり、そのninはDisplayViewです。

このような

    item1.yValue=totalpercentage;
item1.width = 35;
item1.name = @"item1";

ECGraphItem *item2 = [[ECGraphItem alloc] init];
item2.isPercentage = YES;
item2.yValue =17;
item2.width = 35; 
item2.name = @"item2";
/*
 ECGraphItem *item3 = [[ECGraphItem alloc] init];
 item3.isPercentage = YES;
 item3.yValue = 45;
 item3.width = 35;
 item3.name = @"item3";

 ECGraphItem *item4 = [[ECGraphItem alloc] init];
 item4.isPercentage = YES;
 item4.yValue = 78.6;
 item4.width = 35;
 item4.name = @"item4";

 ECGraphItem *item5 = [[ECGraphItem alloc] init];
 item5.isPercentage = YES;
 item5.yValue = 94.45;
 item5.width = 35;
 item5.name = @"item5"; */


NSArray *items = [[NSArray alloc] initWithObjects:item1,item2,nil];
[graph setXaxisTitle:@"name"];
[graph setYaxisTitle:@"Percentage"];
[graph setGraphicTitle:@"Histogram"];
[graph setDelegate:self];
[graph setBackgroundColor:[UIColor colorWithRed:220/255.0 green:220/255.0 blue:220/255.0 alpha:1]];
[graph drawHistogramWithItems:items lineWidth:2 color:[UIColor blackColor]];

     }

すべてのアイテムのパーセンテージを DisplayView に渡す必要がある場合は、DisplayView でメソッドを作成し、

-(void) setPercentageArray:(NSArray*) 配列

次に、GraphsViewController からこのメソッドを呼び出して、次のように配列を渡します。

NSArray *percentages = [NSArray arrayWithObjects:@"80", @"75", @"90", nil];

DisplayView でクラス メンバー変数を作成し、'setPercentageArray' このメソッドがその変数を設定します。

その配列をそれぞれのアイテムに使用します。

編集：

DisplayView の .h で

@interface Display : UIView {

 NSArray *percentages;

}
-(void) setPercentageArray:(NSArray*) array;
@end

DisplayView.m に、このメソッドを追加し、

-(void) setPercentageArray:(NSArray*) array
{
    percentages = array;
}

drawRect メソッドでは、次のようにできます。

 ECGraphItem *item1 = [[ECGraphItem alloc] init];
 item1.isPercentage = YES;
 item1.yValue = 80;     
 item1.yValue= [percentages objectAtIndex:0];
 item1.width = 35;
 item1.name = @"item1";

 ECGraphItem *item2 = [[ECGraphItem alloc] init];
 item2.isPercentage = [percentages objectAtIndex:1]
 item2.yValue =17;
 item2.width = 35; 
 item2.name = @"item2";
