LLSegment--分段控制器及滚动

配置pod "LLSegmentBar"第三方
点进去了看文档
导入#import文件
#import “LLSegmentBarVC.h”
设置属性比如:
@property (nonatomic,weak) LLSegmentBarVC * segmentVC;

//懒加载:

• (LLSegmentBarVC *)segmentVC{
  if (!_segmentVC) {
  LLSegmentBarVC *vc = [[LLSegmentBarVC alloc]init];
  // 添加到到控制器
  [self addChildViewController:vc];
  _segmentVC = vc;
  }
  return _segmentVC;
  }

• (void)viewDidLoad {
  [super viewDidLoad];
  self.automaticallyAdjustsScrollViewInsets = NO;
  [self.navigationItem setHidesBackButton:YES];

  // 1 设置segmentBar的frame
  self.segmentVC.segmentBar.frame = CGRectMake(0, 0, self.view.frame.size.width, 42);
  self.navigationItem.titleView = self.segmentVC.segmentBar;
  // 2 添加控制器的View
  self.segmentVC.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
  [self.view addSubview:self.segmentVC.view];
  //例如想要什么名字自己声明
  NSArray *items = @[@“攻略”, @“训练营”, @“资讯”];

  //控制器的初始化****有几个写几个头文件一定要导入
  ONEViewController *strategy = [[ONEViewController alloc] init];
  TWOViewController *camp = [[TWOViewController alloc] init];
  THREEViewController *consult = [[THREEViewController alloc] init];
  // 3 添加标题数组和控住器数组
  [self.segmentVC setUpWithItems:items childVCs:@[strategy,camp,consult]];
  // 4 配置基本设置 可采用链式编程模式进行设置
  [self.segmentVC.segmentBar updateWithConfig:^(LLSegmentBarConfig *config) {
  // config.itemNormalColor([UIColor colorWithHexString:@"#666666"]).itemSelectColor([UIColor colorWithHexString:@"#188bf0"]).indicatorColor([UIColor colorWithHexString:@"#188bf0"]);
  // 设置字体大小
  // config.itemF = BQBOLDFONT(18);
  }];
