Answer 1

试试这个

NSDictionary *finalres = [result objectForKey:@"DATA"];

for (NSDictionary * finalres in results) {

    NSString *name = [finalres objectForKey:@"name"];

    NSString *images=[finalres objectForKey:@"img"];

    NSLog(@"%@", name);

    NSLog(@"%@",images);

    displayApiLabel.text=[NSString stringWithFormat:@"%@",name];
    NSData *convertData=[images dataUsingEncoding:NSUTF8StringEncoding];

    NSLog(@"%@",convertData);
    UIImage *img=[UIImage imageWithData:convertData];

    NSLog(@"sads%@",img);
}
