DYSegmentView : 自定义滑动控件实现类
具体使用


-(DYSegmentView *)dySegment{
    if (!_dySegment) {
        _dySegment = [[DYSegmentView alloc]initWithFrame:CGRectMake(ScreenWidth/2-120, 25, 240, 44)];
        _dySegment.delegate         = self;
        _dySegment.backgroundColor  = [UIColor clearColor];
        _dySegment.titleNormalColor = UIColorFromRGB(0xffffff, 0.5);
        _dySegment.titleSelectColor = UIColorFromRGB(0xffffff, 0.9);
        _dySegment.titleFont        = [UIFont systemFontOfSize:15];
        _dySegment.titleArray       = @[@"在线",@"附近"];
    }
    return _dySegment;
}
    self.navigationItem.titleView = self.dySegment;

实现相对应的代理方法 <DYSegmentDelegate,UIScrollViewDelegate>


#pragma mark - UIScrollDelegate
-(void)scrollViewDidScroll:(UIScrollView *)scrollView{
    [_dySegment dyDidScrollChangeTheTitleColorWithContentOfSet:scrollView.contentOffset.x];
}
#pragma mark - DYSegmentDelegate
-(void)dySegment:(DYSegmentView *)segment didSelectIndex:(NSInteger)index{
    NSString *notiStr;
    if (index == 1) {
        notiStr = @"1";
    }else{
        notiStr = @"2";
    }
    self.scrollView.contentOffset = CGPointMake(ScreenWidth*(index-1), 0);
    [[NSNotificationCenter defaultCenter] postNotificationName:@"MainViewScrollDidScroll" object:notiStr];
}
