如何assing從其他視圖控制器值自定義的UIView在iphone

Question

我在裏面我是用EASYGRAPH API爲圖我已經顯示視圖創建iPhone應用程序在那裏我得出的百分比和座標圖，我想在這一點，值可能會動態當應用程序是created.Like我有perecentage 78％，那麼應該如何分配此值這是在我的代碼顯示視圖anohter視圖

顯示視圖

#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; 

我想要的百分比在下面設置這是在我的GraohsView控制器，它的nin是DisplayView的方式totoalpercentage

喜歡這張

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]]; 

    } 

GraphicsViewController

} 

    -(void)createGraph{ 


PieClass *myPieClass=[[PieClass alloc]initWithFrame:CGRectMake(50,440,320,230)]; 

myPieClass.backgroundColor=[UIColor clearColor]; 

myPieClass.itemArray=[[NSArray alloc]initWithObjects:valueOne,valueTwo,valueThree,valueFour, nil]; 

myPieClass.myColorArray=[[NSArray alloc]initWithObjects:[UIColor blueColor],[UIColor redColor],[UIColor greenColor],[UIColor brownColor], nil]; 

myPieClass.radius=100; 

[self.view addSubview:myPieClass]; 

    } 

Answer 1

，如果你需要通過每一個項目DisplayView的比例，使DisplayView的方法，

- （空）setPercentageArray：（NSArray的*）陣列

然後調用從GraphsViewController這種方法並傳遞數組，如

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

在DisplayView中創建類成員變量，'setPercentageArray'這個方法將設置該變量。

對各個項目使用該數組。

編輯：

在DisplayView.m .H DisplayView

@interface Display : UIView { 

NSArray *percentages; 

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

，加此法，

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

中的drawRect方法

，U可以這樣做，

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";
