Can not be very easy to control whether to display the percent sign

[Asingers]

Can not be very easy to control whether to display the percent sign, your project is not through the control switch, you may be able to add a bool attributes to control, I tried, realize, and convenient.
You may see this:
Add:

MDRadialProgressView.h

// 控制是否显示显示百分号
// whether or not
@property(nonatomic,assign) BOOL isShowPercentMark;

"MDRadialProgressView.m"

 if (self.isShowPercentMark == YES) {
             text = [NSString stringWithFormat:@"%.0f%%", percentageCompleted];
        }else if (self.isShowPercentMark == NO){
        text = [NSString stringWithFormat:@"%.0f", percentageCompleted];
        }
