仿网易新闻侧滑视图

使用方法：

NSMutableArray *vcs = [NSMutableArray array];
for (int i = 0; i < 10; i++) {
    UIViewController *vc = [[UIViewController alloc] init];
    vc.title = [NSString stringWithFormat:@"%d", i];
    vc.view.backgroundColor = [UIColor colorWithRed:((255.0 * (i%2)) / 255) green:((255.0 * ((i+1)%2)) / 255) blue:((255.0 * ((i+2)%2)) / 255) alpha:1];

    UILabel *label = [[UILabel alloc] initWithFrame:vc.view.bounds];
    label.text = [NSString stringWithFormat:@"%d", i];
    label.textAlignment = NSTextAlignmentCenter;
    label.font = [UIFont fontWithName:@"MarkerFelt-Thin" size:100];
    label.textColor = [UIColor purpleColor];
    label.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;
    [vc.view addSubview:label];

    [vcs addObject:vc];
}

GXSlideSegmentController *slideSegmentController = [[GXSlideSegmentController alloc] initWithViewControllers:vcs];
slideSegmentController.title = @"GXSlideSegmentController";
slideSegmentController.indicatorInsets = UIEdgeInsetsMake(0, 8, 0, 8);
slideSegmentController.indicator.backgroundColor = [UIColor redColor];
slideSegmentController.indicator.layer.cornerRadius = slideSegmentController.indicator.frame.size.height/2;
[self.navigationController pushViewController:slideSegmentController animated:YES];
