寫了lines、RKLineView、getData三個物件完成實現。

首先開始呼叫

rkLine = [[RKLineViewalloc]init];

        CGRect frame =riKView.frame;

         frame.origin =CGPointMake(0,5);

         frame.size =CGSizeMake(315,219);

        rkLine.frame = frame;

        rkLine.xWidth =315;

        rkLine

.yHeight =219;

rkLine.kLineWidth =4;

rkLine.kLinePadding =1.25;

        rkLine.riKArry = [dicobjectForKey:@"rows"];

         [riKViewaddSubview:rkLine];

         [rkLinestart];// 線圖執行

其它3個物件部分程式碼如下

#import <UIKit/UIKit.h>

@interface lines : UIView

@property (nonatomic,assign)CGPoint startPoint;//線條起點

@property (

nonatomic,assign)CGPoint endPoint;//線條終點

@property (nonatomic,retain)NSArray *points;//多點連線陣列

@property (nonatomic,retain)NSString *color;//線條顏色

@property (nonatomic,assign)CGFloat lineWidth;//線條寬度

@property (nonatomic,assign)BOOL isK;//是否是實體K線預設是連線線

@property (nonatomic,assign)BOOL isVol;//是否是畫成交量的實體
