 NOTE:获取组按钮默认创建实现方式如下：
 +(WHC_ButtonGroupParam *)getDefaultParamWithTitleArr:(NSArray*)titleArr{
     WHC_ButtonGroupParam * groupParam = [WHC_ButtonGroupParam new];
     groupParam.normalBackColor      = [UIColor grayColor];
     groupParam.selectedBackColor    = [UIColor blackColor];
     groupParam.markColor            = [UIColor clearColor];
     groupParam.segmentLineY         = 0.0;
     groupParam.segmentLineColor     = [UIColor blackColor];
     groupParam.normalTextColor      = [UIColor whiteColor];
     groupParam.selectedTextColor    = [UIColor grayColor];
     groupParam.titles               = titleArr;
     groupParam.images               = nil;
     groupParam.scroll               = NO;
     groupParam.headLine             = YES;
     groupParam.footLine             = YES;
     groupParam.firstSegmentLine     = YES;
     groupParam.markViewDown         = NO;
     groupParam.fontSize             = 16.0;
     groupParam.markPading           = 5.0;
     return groupParam;
 }
