如果您使用 json 概念，请尝试此操作

NSString *urlString = [NSString stringWithFormat:"your url link"];     
NSURL *url = [NSURL URLWithString:urlString];
NSData *data = [NSData dataWithContentsOfURL:url];
NSError *error;
NSMutableArray *json = (NSMutableArray*)[NSJSONSerialization JSONObjectWithData:data options:kNilOptions error:&error];
NSMutableArray *piimage=[json valueForKey:@"pi_image"];
NSLog(@"%@",piimage);
