Ios 如何显示JSON中图像的水平滚动视图

我的JSON响应

 {"result":0,"data":[{"bannerslider_id":"1","img":"http:\/\/whatsinthestreet.com\/media\/bannerslider\/images\/slider1.jpg"},{"bannerslider_id":"2","img":"http:\/\/whatsinthestreet.com\/media\/bannerslider\/images\/slider2.jpg"},{"bannerslider_id":"3","img":"http:\/\/whatsinthestreet.com\/media\/bannerslider\/images\/slider3.jpg"},{"bannerslider_id":"4","img":"http:\/\/whatsinthestreet.com\/media\/bannerslider\/images\/slider4.jpg"}]}

我写了这样的代码

（void）视图显示：（BOOL）动画{
[[[NSURLSession sharedSession]dataTaskWithURL:[NSURL URLWithString:@]http://whatsinthestreet.com/allbanners.php“]completionHandler:^（NSData*\u可为空的数据，NSURLResponse*\u可为空的响应，NSError*\u可为空的错误）{
NSLog（@“响应%@”，响应）；
NSLog（@“数据%@”，数据）；
NSDictionary*dict=[NSJSONSerialization JSONObjectWithData:数据选项：NSJSONReadingMutableLeaves错误：nil]；
NSLog（@“dict%”，dict）；
NSArray*阵列；
数组=[dict valueForKey:@“data”]；
NSLog（@“%@”，数组）；

我得到的答复是

 dict{
    data =     (
                {
            "bannerslider_id" = 1;
            img = "http://whatsinthestreet.com/media/bannerslider/images/slider1.jpg";
        },
                {
            "bannerslider_id" = 2;
            img = "http://whatsinthestreet.com/media/bannerslider/images/slider2.jpg";
        },
                {
            "bannerslider_id" = 3;
            img = "http://whatsinthestreet.com/media/bannerslider/images/slider3.jpg";
        },
                {
            "bannerslider_id" = 4;
            img = "http://whatsinthestreet.com/media/bannerslider/images/slider4.jpg";
        }
    );
    result = 0;
}

如何从这些值访问图像以获得图像的水平滚动视图？

这应该适合您

-(void)viewDidAppear:(BOOL)animated{
    [[[NSURLSession sharedSession] dataTaskWithURL:[NSURL URLWithString:@"http://whatsinthestreet.com/allbanners.php"] completionHandler:^(NSData * _Nullable data ,NSURLResponse * _Nullable response,NSError * _Nullable error){
        NSLog(@"response %@",response);
        NSLog(@"data %@",data);
        NSDictionary *dict=[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableLeaves error:nil];
        NSLog(@"dict%@",dict);
       NSArray *array;
        array=[dict objectForKey:@"data"];
       NSLog(@"%@",array);
       for(id obj in array)
       {
            NSString *urlStr=[obj objectForKey:@"img"];
        }
}

[array valueforkey:@“img”]objectAtIndex:0]您获得了第一幅横幅图像您的滚动视图代码在哪里？您在哪里创建图像？@Bhavani chada现在您必须将urlsrt转换为NSURL对象，然后您可以继续…干杯
