//①先导入头文件

#import "MBDICycleScrollView.h"

//②初始化滚动视图和图片数组

@interface LUNBOViewController (){

MBDICycleScrollView * ScrolView;

NSMutableArray * imgData;

NSMutableArray * imgViews;

}

@end

- (void)viewDidLoad {

[super viewDidLoad];

self.view.backgroundColor = [UIColor whiteColor];

self.navigationItem.title = @"无限滚动视图";

//初始化滚动视图 设置位置及大小 P1 frame P2跳转一次的时间

ScrolView = [[MBDICycleScrollView alloc]initWithFrame:CGRectMake(0, 200, self.view.frame.size.width, 300) animationDuration:2];

//初始化imgView 数组

imgViews = [[NSMutableArray alloc]init];

//将滚动视图添加到视图上

[self.view addSubview:ScrolView];

//将图片添加到可变数组里

imgData = [NSMutableArray array];

for (NSInteger i = 1; i<7; i++) {

[imgData addObject:[NSString stringWithFormat:@"%ld.jpg",(long)i]];

}

//调用updateScrolView 方法

[self updateScrolView];

}

-(void)updateScrolView{

//向图片数组里添加图片，并将图片添加到视图上

imgViews=[NSMutableArray array];

[imgViews removeAllObjects];

for (int i =0; i

UIView *photoV = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 300)];

//设置用户交互性（View 能被点击）

[photoV setUserInteractionEnabled:YES];

UIImageView *imgv = [[UIImageView alloc]initWithFrame:photoV.bounds];

[imgv setUserInteractionEnabled:YES];

[imgv setContentMode:UIViewContentModeScaleAspectFill];

//网络请求数组

//                [imgv sd_setImageWithURL:[NSURL URLWithString:_CycleDataList[i][@"img"]] placeholderImage:IMAGEDEFAULT completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) {

//                } ];

[imgv setImage:[UIImage imageNamed:imgData[i]]];

[photoV addSubview:imgv];

[imgViews addObject:photoV];

}

__block __weak LUNBOViewController *weakSelf = self;

//调用 setArrayView 方法

ScrolView.arrayView = imgViews;

//赋值 block 代码块

ScrolView.TapActionBlock = ^(NSInteger pageIndex){

NSLog(@"tap:%ld",(long)pageIndex);

//自身调用方法

[weakSelf tapClick:pageIndex];

};

}

-(void)tapClick:(NSInteger)index{
