IOS 股票K线图的实现
写了lines、RKLineView、getData三个对象完成实现。
首先开始调用
rkLine = [[RKLineView alloc] 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 = [dic objectForKey:@"rows"];
[riKView addSubview:rkLine];
[rkLine start]; // 线图运行
其它3个对象部分代码如下
#import <UIKit/UIKit.h>
@interface lines : UIView
@property (nonatomic,assign) CGPoint startPoint; // 线条起点
@property (nonatomic,assign) CGPoint endPoint; // 线条终点
@property (nonatomic,retain) NSArray *points; // 多点连线数组
@property (nonatomic,retain) NSString *color; // 线条颜色
@property (nonatomic,assign) CGFloat lineWidth; // 线条宽度
@property (nonatomic,assign) BOOL isK;// 是否是实体K线 默认是连接线
@property (nonatomic,assign) BOOL isVol;// 是否是画成交量的实体
@end
