CYPieChart is a subclass of UIView that displays your data in a pie chart.
By default ,all the description labels are place within the pie chart.
By these labels can also be placed outside.
Simply add
use_frameworks!
and
pod 'CYPieChart'
to your Podfile ,and Cocoapods does the magic !
Clone or download the project , drag the entire CYPieChart Folder into your project , and then :
#import "CYPieChart.h"
,and you are ready to go.
To use CYPieChart ,your code would be something like this:
for (NSUInteger i = 0; i < count; ++i)
{
PieChartDataObject *obj = [[PieChartDataObject alloc] initWithTitle:@"String Representation Of Your Data" value: value of your data];
[objectArray addObject:obj];
}
for (NSUInteger i = 0; i < count; ++i) {
[colorArray addObject:UIColor Object];
}
self.pieChart.objects = objectArray;
self.pieChart.colors = colorArray;
[self.pieChart updateAppearance];
You specify what data the chart is going to present along with the colors that it uses presenting those data , you can also set other properties such as moveRadius , titlePosition to customize the appearance of the chart. At last , you MUST call [pieChart updateAppearance] to notify the pie chart to update its appearance.
Add new feature ,labels can no be placed outside , set pieChart.titleLayout = TitleLayout_Bottom or pieChart.titleLayout = TitleLayout_Right will do the trick.
Notice that if you place the labels outside the pie chart , the value of titlePosition will not be used.
For more detail ,plz clone or download the zip and view the sample project.
If there is any problems / suggestions ,I'll be very grateful to hear from you!
