mTagView = [[ScrollTagView alloc]initWithFrame:CGRectMake(0, 64, SCREENWIDTH, SCREENHEIGHT)];
mTagView.showWidht = SCREENWIDTH;
mTagView.totalCols = 4;
mTagView.labTextFont = 12;
mTagView.spaceLeft = 10;
mTagView.spaceRight = 10;
mTagView.cornerValue = 5;
mTagView.labWidht = (SCREENWIDTH-50)/4;
mTagView.textColor = [UIColor grayColor];
mTagView.labHeight = 30;
mTagView.spaceTBMargin = 20;
mTagView.isShowSelectedBg = YES;
mTagView.scrollTagViewDelegate = self;
[mTagView setTagArray:mDataSource];
[self.view addSubview:mTagView];
//此代理可知选中后又取消的标签
- (void)scrollTagView:(ScrollTagView *)tagView didSelectTagAtIndex:(NSInteger)index
{
}
//选中的标签
- (void)scrollTagView:(ScrollTagView *)tagView cancelSelectTagAtIndex:(NSInteger)index
{
}
