如何访问字典或数组中的内容？
在我的应用程序中，我有一些我无法处理的特殊场景。 我从 Xml 获取数据，并将其放入两个数组 Label 和 numProjects 中。 Label 包含标签，numProjects 包含各个标签的值。
有了这些值，我需要为每个标签绘制一个具有不同颜色的饼图。 我绘制图表的方式是将填充图表所需的数据放入一个数组中，并在另一个数组中放入不同部分所需的颜色。
所以这是代码的问题：
labelArray = [Active, pipeline, closed];
numProjectArray = [248, 438,200];// respective values as per the labelArray
现在在绘图时我需要这个 numProjectArray 并且我还需要创建另一个数组，其中包含我想要为各个部分着色的所有颜色。每个标签值颜色也应该有一个特定的对。对于每个标签，应该有一个存储在 numProjectArray 中的唯一值，对于这个标签值对，我们需要特定的颜色来绘制该部分。并且还需要在图表一侧显示此信息，其中颜色表示哪个标签。
请帮忙！！！
In my app i have some special scenario which i am not able to handle.
I am getting data from Xml which i am putting in two Arrays Label and numProjects.
Label contains labels and numProjects contains values for respective labels.
With these values i need to draw a pie chart with different colors for each label.
The way i am drawing the chart is i put the data with which i need to populate the chart in one array and in other array i put colors which i need for different sections.
So here's the problem with code:
labelArray = [Active, pipeline, closed];
numProjectArray = [248, 438,200];// respective values as per the labelArray
Now while drawing i need this numProjectArray and also i need to create another array which has all the colors i want to color the separate sections. Also there should be a specific pair for each of label-value-color. For each label there should be a unique value which is stored in numProjectArray and for this label-value pair we need a specific color to draw the section. And also need to display this information on side of graph that which color denotes which label.
Please help!!!

如果您问如何做得更好，您可能应该考虑类似字典数组的东西，每个标签/值/颜色一个字典。每个字典都有@“label”、@“numProjects”和@“color”等键以及相应的值。
If you're asking how to do this better, you should probably be thinking about something like an array of dictionaries, with one dictionary per label/value/color. Each dictionary would have keys like @"label", @"numProjects", and @"color", and corresponding values.
