iOS 数组~画饼图-添加数据优化

//联系人:石虎 QQ:1224614774 昵称:嗡嘛呢叭咪哄

一、概念

 - (void)viewDidLoad {

     [superviewDidLoad];

     //初始化

     SHPieChart *chart = [[SHPieChart alloc]initWithFrame:CGRectMake(0,40, SHSCREEN_WIDTH, SHSCREEN_HEIGHT /3.0f )];

     chart.backgroundColor = [UIColor orangeColor];

     [self.view addSubview:chart];

 

 }

二、最基本的写法-也是最笨的方法

  // 常见方法

  - (void)commonMethods{

  //创建数据模块

  SHChartPointItem *item1 = [SHChartPointItem chartPoinItemWithRawX:@"敲代码" andRowY:@"0.33"];

  SHChartPointItem *item2 = [SHChartPointItem chartPoinItemWithRawX:@"调程序" andRowY:@"0.34"];

  SHChartPointItem *item3 = [SHChartPointItem chartPoinItemWithRawX:@"吃饭费" andRowY:@"0.23"];

  SHChartPointItem *item4 = [SHChartPointItem chartPoinItemWithRawX:@"其他" andRowY:@"0.1"];

  pieChartData.items = @[item1,item2,item3,item4].mutableCopy;

  pieChartData.fillColors = @[[UIColor redColor],[UIColor blueColor],[UIColor cyanColor],[UIColor yellowColor]].mutableCopy;

  chart.pieChartData = pieChartData;

  [chart strokeChart];

  }

三、推荐方法

   

  //推荐方法

  - (void)recommendedApproach{

   NSArray *titleArray =@[@"0.33",@"0.34", @"0.23",@"0.1",@"0.33",@"0.34", @"0.23",@"0.1"];

   NSMutableArray *itemArrayM = [NSMutableArrayarray];

   SHPieChartData *pieChartData = [[SHPieChartData alloc]init];

   for (int i =0; i < titleArray.count; i++) {

    

       SHChartPointItem *item = [SHChartPointItem chartPoinItemWithRawX:@"" andRowY:titleArray[i]];

       [itemArrayM addObject:item];

  }

   pieChartData.items = itemArrayM.mutableCopy;

   chart.pieChartData = pieChartData;

   [chart strokeChart];

    

   }

谢谢!!!
