我需要使用 JSON 提取数据，然后将它们放入 UITableView，但是当我尝试提取它们时出现此错误。
-JSONValue failed. Error is: Illegal start of token [E]
网站里的数据很多，10万多条，也许太多了？我的代码：
#import <UIKit/UIKit.h>
#import "SBJson.h"
@interface ProductsViewController : UIViewController <UITableViewDataSource, UITableViewDelegate, NSURLConnectionDataDelegate> {
NSURLConnection *conn;
NSMutableData *webData;
}
在 ProductsViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
NSURL *url=[NSURL URLWithString:@"http://www.e-xxxxxxx.it/virtualShop/pageflow/address/xxxxxxxxxxxx.do?json=true&vsIdxxxxxxxxxxxxxxxxxxxxxxxxxx=Ext.data.JsonP.callback1"];
NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
conn =[[NSURLConnection alloc]initWithRequest:req delegate:self];
if(conn){
webData =[[NSMutableData alloc]init];
}
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{
[webData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
[webData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error{
NSLog(@"Connection failed: %@", [error description]);
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection{
NSLog(@" the number of data is %d", [webData length]);
//the number of data is 104557
NSString *strResult =[[NSString alloc]initWithData:webData encoding:NSUTF8StringEncoding];
NSDictionary *result =[strResult JSONValue];//the error is here
for (id obj in result){
NSLog(@"%@", result);
}
}
他的字符串strResult很长，这是一段
