1.导入头文件
2.创建类SliderContentViewController继承于UIViewController

//

#import "ViewController.h"
#import "YJSliderView.h"
#import "SliderContentViewController.h"
@interface ViewController ()<YJSliderViewDelegate>
@property (nonatomic, strong) YJSliderView *sliderView;
@property (nonatomic, strong) NSArray *contentArray;
@property (nonatomic, strong) NSArray *titleArray;


@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    //需要将UIView的自动调整ScrollViewInset关闭
    self.automaticallyAdjustsScrollViewInsets = NO;
    self.sliderView = [[YJSliderView alloc] initWithFrame:CGRectMake(0, 64, self.view.frame.size.width, self.view.frame.size.height)];
    self.sliderView.delegate = self;
    self.titleArray = @[@"灰色", @"黄色黄色", @"紫", @"橘色", @"蓝色"];
    [self.view addSubview:self.sliderView];
}
//这里是设置显示的title个数
- (NSInteger)numberOfItemsInYJSliderView:(YJSliderView *)sliderView {
    return _titleArray.count;
}

- (UIView *)yj_SliderView:(YJSliderView *)sliderView viewForItemAtIndex:(NSInteger)index {
    SliderContentViewController *vc = [[SliderContentViewController alloc] init];
    if (index == 0) {
        vc.view.backgroundColor = [UIColor lightGrayColor];
    } else if (index == 1) {
        vc.view.backgroundColor = [UIColor yellowColor];
    } else if (index == 2) {
        vc.view.backgroundColor = [UIColor purpleColor];
    } else {
        vc.view.backgroundColor = [UIColor orangeColor];
    }
    return vc.view;
}
//设置显示的title
- (NSString *)yj_SliderView:(YJSliderView *)sliderView titleForItemAtIndex:(NSInteger)index {
    return self.titleArray[index];
}
//设置默认选择的title
- (NSInteger)initialzeIndexFoYJSliderView:(YJSliderView *)sliderView {
    return 3;
}
